Here at BlueDevil, we are starting a new segment of our blog devoted to answering your questions about your vehicle. Many makes and model cars today use very similar equipment, but in some cases there are subtle, or not so subtle, differences and if you’re working on an older or late model car you may need even more direction. Whether you have a question specific to one of our products and how it is used to fix your particular problem, or any other maintenance question we would love to help you find the answer and get your vehicle back on the road quickly and painlessly.
Whether one of our guaranteed products can solve your problem or not, we are here to help. All we need from you is a little information about your vehicle, and the problem you are having with it. For the information about your vehicle you can check in a few places. There should be a white sticker somewhere on the driver side door jamb with the make, model and date your vehicle was manufactured. You can also check on your vehicle registration or insurance card. As far the problem you are having, the more information you can give us, the more accurate our diagnosis and solution can be. Try to remember the first time you identified the problem, the most specific location you can describe the noise, leak or other problem coming from, and any other symptoms that may have occurred in conjunction with it like rattles, clunks, squeaks or other malfunctioning equipment.

Hi my name is Jamal I have a 03 ford explorer Eddie bauer edition with a v8 .I’m getting the chocolate milk look in my oil cap I believe I am getting coolant in my oil.how much blue devil should I use?and do I have to change the thermostat?
Jamal-
You would need 32 oz. of the BlueDevil Head Gasket Sealer to treat your Ford Explorer. You may use either of the Head Gasket Sealers that we manufacture. The “Pour N Go” (16 oz./white label) is an easy to use, less concentrated formula that does not require the removal of the thermostat or a flush of the cooling system prior to use. Whereas the “Mechanic Approved” (32 oz./yellow label) requires both the removal of the thermostat and a flush before applying the product; the 32 ounce (yellow label) is the more concentrated formula. The product with the yellow label will give you best overall results as long as you are willing to remove the thermostat and flush the system prior to use.
Thank you!

I have a 1993 mazda b2200 2.2 4 cylinder. I’m getting too much pressure in my cooling system. the coolant is being pushed out into the overflow. water pump, thermostat and radiator cap or new. I think I have a head gasket problem. Can your product fix this problem.
Larry-
As you mentioned, it sounds like the vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure. We would recommend using the BlueDevil Head Gasket Sealer.
To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak. If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull. Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly.
Feel free to contact us with any questions (888.863.0426).

My partner and just replaced the radtior and hoses and thermostate last week
and we are still leaking antifreeze? Also it stays around 210 on the temp gage but never any higher and the car has be hotter then what the temp says why could be wrong
Heather-
We recommend using BlueDevil Head Gasket Sealer for your vehicle.
It sounds like the vehicle may be getting combustion/exhaust gases blowing into the cooling system and creating pressure. To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading. If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull. Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly. Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

Hi.. The little metal 10mm power steering return line that runs along just underneath my radiator has a small kink in it from when I ran up on a curb recently. Every since, I’ve notices that on a cold start only, I get the nosey whining noise for about 5mins then goes away! My guess is that air is seeping into the line thru the small kink thats in it now. (it may be only a 10mm hose, but the small kink is substantial enough to maybe of punctured a tiny hole near the kink as well…) Haven’t noticed any increased trouble with turning the wheel either.. Just the brief noise when starting my cold engine.
Will your Blue Devil Power Steering Leak Stop be a good remedy for this problem or is it only made for repairing leaking seals, etc.?!? Thank you!
Brandon-
Unfortunately, we do not manufacture any products that are intended to fix the type of leak you are experiencing. The BlueDevil Power Steering Stop Leak is specifically designed to stop fluid loss from any rubber seal or gasket.
The only solution may be to have the hose replaced.
Thank you!
-BDP
Thank you do much for your timely response. I will do a hose replacement..

HI, I have a altima 05,there is no withe smoke, no oil mix with anrifreeze but sometimes when I start the car the engine start shaking hard an the antifreeze are low when I completed the radiator the car running fine. Could be head gasket problem? Can I use por and go he’d gasket sealer bd with hot antifreeze?
Dennys-
Thank you for asking about your Nissan Altima. Based on your description, we would recommend using the BlueDevil Pour-N-Go Head Gasket Sealer, found here: http://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/ . As the directions state, you will be starting the process with the vehicle off and the engine cold. Feel free to contact our technical support line at 888-863-0426 with any other questions.

I have a 2007 Ford Focus, my power steering started to get that bad whine at about 120,000 miles so I replaced it. It worked great the first day and then the next day it didn’t make any noise at all and just stopped working, there’s no sound or anything it just takes all my strength to turn. I put it on jack stands and it turns easy enough but the fluid doesn’t rise or fall, what can I do next?
James,
Thanks for your question about your 2007 Ford Focus. For you system to suddenly fail like that without any other sound or warning you may have a broken belt or a pump with a broken pulley. Try checking under your hood and seeing there is anything obviously out of place. If the new power steering pump looks fine, then the problem must be internal to your power steering rack. It is possible that when your old power steering pump was going bad it allowed particles or debris into your system that caused an internal failure in your power steering rack. That would explain the difficulty in turning and the lack of fluid flow in the reservoir when turning your steering wheel.
Thanks again for your question!

I have a 2006 Toyota Camry, I recently noticed that when I start my car after it sits for a while or over night, white smoke comes from the tail pipe. Car runs fine, not over heating. I have noticed that it trembles when I turn on the a/c. Had it checked out, does not seem to be losing oil or coolant, but a dye test was done on it. I was told that the oil and coolant was mixing. No milky oil. Can your product fix this problem?
Shae-
Thank you for asking about your Toyota Camry. If the vehicle was diagnosed as the oil and coolant mixing, and there is no water/coolant in the oil, the oil may be getting into the radiator or other part of the cooling system. The BlueDevil Head Gasket Sealer is only intended for water/coolant leaks. Unfortunately, we do not manufacture a product for this type of a leak. A hard part repair may be your best option.
Hope this helps!

Hi I have a 2006 Ford F450 with a 6.0 turbo diesel. Currently there is a leak in the head gasket at some point along the cooling channel of the fuel injectors and the fuel diesel is leaking into the cooling system.
According to the directions on the bottle it seems though as if you need to have the cooling system completely free of contaminants i.e. Coolant, for the blue devil head gasket product to work? I can flush out my cooling system however within a certain timeframe unknown time at this point but the coolant will get contaminated or the flushed system will be contaminated with diesel fuel, and I’m wondering if the product will still work under the conditions that the cooling system will get contaminated with diesel fuel. Or do you think it’s possible that the blue devil product will seal the leak for the diesel fuel leaking into the cooling system before it gets over contaminated with diesel fuel?
Joey-
Thank you for asking about your Ford F450. Have you confirmed this as a head gasket leak? Based on your description, it sounds like you may have cracked injector cups. Unfortunately, we do not recommend using the BlueDevil Head Gasket Sealer for this type of leak. We recommend bringing the vehicle to a certified ASE mechanic for a proper diagnosis. Some shops actually have a special tool to pull the injector cups to replace them without having to remove the heads. Feel free to contact us at 888-863-0426 with any other questions.

Are used the radiator flush from blue devil and it worked I had pressure in my top hoseand in my reservoir. Now it’s not working again I have no pressure in my top hose or in the reservoir. I flushed two weeks ago should I flush again ?
Gentry-
Are you noticing any other symptoms, like a loss of water/coolant or anything of that nature? Is the vehicle overheating at all?

My 2004 Pontiac Grand Am keeps overheating. I changed the thermostat. I don’t see any leaks. It runs fine but won’t start back right away i have to wait until it cools down. Im not sure if its a temp sensor or a gasket blown.
Isha-
Thank you for asking about your Pontiac Grand Am. Unfortunately, there are a number of a different reasons for why a vehicle might overheat, even without losing coolant. Are you noticing good circulation in the cooling system? Has the water pump been replaced recently? Based on your description, we recommend taking the vehicle to a certified ASE mechanic for a proper diagnosis.
Thank you!

So I own a 2013 Dodge Avenger SE with the 3.6l V6 VVT engine. When I accelerate it sometimes produces a whining noise( best way to describe it is the sound of a supercharger… but Unless my mechanic and the dealership (used car) missed an aftermarket one…. it doesnt have a supercharger)
What could be causing this?
Hunter-
Thank you for asking about your Dodge Avenger. Based on your description, it is possible that you are in need of a wheel bearing replacement. Do you notice the sound when you are turning the steering wheel? Please contact our technical support line at 888-863-0426 so that we can get a better idea of the vehicle’s condition and be able to make any appropriate recommendations.

I have a UTV that just developed a leak in the front differential. Can I use this product to stop the leak? If so how much should I use? My differential takes 180ml of gear oil. My quick math says I should add 0.4 oz of Oil Stop Leak. Is that about right?
Mike-
Thank you for asking about your UTV. Yes, the BlueDevil Oil Stop Leak would treat a leaking differential. Based on your description, we recommend using about 0.05 oz. of the product.

Hello, I have a 2004 Mercedes benz s55 AMG. I need help with my a/c. A/c is not blowing air in the front vents. I already done checked the blower motor and the resistor both are good and also checked my fuses which are good as well. My back vents blow air bcuz it has a different blower motor. Need help thanks
Victor-
Thank you for asking about your Mercedes Benz S55 AMG. Are you saying that you are not getting any air out what so ever or the air is not as cold as it should be? Does the refrigerant appear low? Please contact our technical support line at 888-863-0426 so that we can get a better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

i have a juke 2011 sv and the other day my air quit like it was set on 60 and nothing i was like no and i did everything like killed the car restarted it and nothing then all of of a sudden it started we t4ested it to see if it had a leak with that glowing neon green stuff and nothing but pressure was relieved when we moved the black cap to put the suff in and no leaks and then it quit the other day like it doesnt do anything no fan no cool no hot like i turned the car off what do you think could be wrong
Carol,
Thanks for your question about your 2011 Juke. Since your air is working and stopping suddenly our guess would be that the problem isn’t with a loss of refrigerant, but an electrical problem either with your air conditioning system or with your ventilation fan. If the fan isn’t blowing any air from the vents the that is your first problem to get fixed. If that fan isn’t blowing then it isn’t getting power either from the fan switch through a resistor if you have manual fan control, or through the ventilation module if you have automatic climate control in your car. If the fan is blowing, but the air coming out is warm, then the problem is with your air conditioning system. It could be a bad sensor, a bad compressor clutch or a short or break in one of the wires controlling those components.
Thanks again for your question!

I have a 2006 chevy equinox. I have no blown fuses and power to all my components but my car won’t start but tries and my windshield wipers and windows won’t work what could be the issue no blown fuses found and radio works and dash lights up
Lutisa-
Thank you for asking about your Chevy Equinox. Based on your description, you can try charging/replacing the battery to see if that’s the culprit. If the battery is low, it may try to turn on, but not have enough power to do so.
Hope this helps!

Hi, this is Don. I used the 16oz pour and go in my 2001 buick about 2 yrs ago and it did the job….recently my coolant is not staying put in my radiator and there’s no leaking on the ground…can i use the pour and go again?

Thank you for asking about your Buick. Are you having any other symptoms, other than the noticeable loss of coolant?

I have a 1996 Mercury Sable and when i turn or go over bumps on the front right side it makes like a popping sound?
Sara-
Thank you for asking about your Mercury Sable. The noise you are hearing could be due to something being loose in the suspension. A popping or clicking noise when turning is a symptom of a bad outer CV joint. If the CV joint is noisy, it needs to be replaced. Also, some worn wheel bearings can often be detected by rocking the vehicle from side to side at low speeds with the steering wheel.
Hope this helps!

I have a 2012 chevy cruze with bubbles blowing back into the coolant reservoir. Car over heated briefly due lost coolant from a broken hose. It this type of blown gasket too big or severe for liquid gasket repair or do I need to remove the bad plug and fuel injector before giving this a try?
Ken-
Thank you for asking about your Chevy Cruze. Based on your description, it sounds possible that you are getting combustion/exhaust gases pumping back into the cooling system. You can use a “Block Dye Tester” to confirm whether or not that is the case.
BlueDevil Head Gasket Sealer will still work if your vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure. To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading. If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull.

I have taken my 2005 Jaguar s-type 4.2 w/82,300 miles to three mechanics. The first one said this car has some serious oil leaking and advised that I take it to a Jaguar mechanic. I then took it to a foreign car mechanic who diagnosed the problem as a timing chain cover leak but was not in a position to do the repairs. The third foreign car repair mechanic specializes in European cars, including Jaguar. They poured a dye into the oil and used a UV light to see where the oil was coming from and they, too, confirmed it was a timing chain cover leak. The labor alone is stated at $1,700 and parts and fees = $550.00. Parts replaced: crankshaft seal; two timing cover gaskets; two valve cover gaskets; an ACC tensioner; spark plug seal; 8 spark plugs; and one drive belt.
You can guarantee that by using your Blue Devil Oil Stop Leak, I can eliminate my oil leak and not have any further problems??? How is this possible? Please make me confident in this approach.
Thanks,
Steve Hara
Steve-
Thank you for asking about your Jaguar S-type. As the long as the leak you are experiencing isn’t more than seeping or lightly dripping, you would be a good candidate for the BlueDevil Oil Stop Leak. The product does not harden or thicken in anyway, so it would not cause any harm to the engine. The product also carries a money-back guarantee. If it is unable to seal for whatever reason, you are able to contact us and be refunded for your purchase. Absolutely worth it to give the product a try.
Thank you!

I have a 2006 Pontiac Grand Prix when I started it drives smoothly shift gears smoothly when I cut it off and restart it it doesn’t shift at all do you know what the problem could possibly be
Gwappo-
Thank you for asking about your Pontiac Grand Prix. In a situation like this, The best place to start would be to flush your transmission, change the fluid along with the filter and then double check to make sure the fluid level is correct. Having dirty/old transmission fluid or the fluid level too high or too low can cause the transmission to act up and not function properly. If you are still experiencing the same shifting issues after changing the fluid and filter and topping it off to the proper level then you may want to have your vehicle looked at by a transmission specialist.
Thank you!

Can the blue devil sealant be used on a 1987 Ford F-350 with the 6.9 idi Diesel engine? Every 21 gallons a f fuel used I leak a quart of oil.

Is there a blue devil product that will repair my head gasket leak. It’s leaking oil externally and dripping onto my driveway.

Unfortunately, we do not manufacture any products that will work to stop oil from leaking from the head gasket. Replacing the head gasket may be the best option in this case.

i just used your rear main sealer as it was leaving and orange size pool of oil after every drive. after 100km of driving and 1 hour idle, the leak has completely stopped. excellent product!!!!! and i’ve never left a review of anything before.
Ben-
Thank you for sharing! We appreciate you taking the time to leave us your feedback and glad to hear that the BlueDevil Rear Main Sealer was able to seal your leak. Once the product seals, it would be a permanent seal, so you should be good to go at this point.

I have a 2010 chevy cruze and there is no radiator cap. Only a reservoir cap. Should I pour this into the coolant reservoir?
Garry-
Thank you for asking about your Chevy Cruze. If your vehicle only has a reservoir/overflow rather than a radiator cap, instead of pouring BlueDevil through the reservoir/overflow, with the car off and engine cold you should disconnect the top radiator hose and add the product there; do not pour it into the reservoir. It may be added into the hose or the opening on the radiator. Once BlueDevil has been added, reconnect the hose and start the idle from that point.
Thank you!

I have a 2007 mustang v6 4.0 sohc. The engine jumped time and bent the valve in the head. So i lapped and replaced all the valves, replaced the entire timing chain system, and of course replaced the headgaskets and head bolts. Well when i start the car it it pours smoke out the exhaust. I assume its oil thats being burned because the oil level drops almost to empty after about 5 to 10 miles of driving. Will your blue devil headgasket sealer work to repair this problem?
Jodie-
Thank you for asking about your Ford Mustang. BlueDevil Head Gasket Sealer is only intended to treat water/coolant leaks. Unfortunately, we do not manufacture a product intended to stop oil leaks from the head gasket. What color is the smoke that is coming out of the exhaust? Keep in mind, a blue smoke would indicate oil burning where as a white smoke/steam would indicate water/coolant burning
Thank you!

Can Blue Devil Pro, which I bought to eliminate a meal in my power steering fluid, also be used to tackle problems with leaking engine oil? Or di I need another Blue Devil product?
Nick-
Yes, the BlueDevil PRO Universal Leak Repair would be able to treat an engine oil leak. You would use one oz. of the product per quart of oil in the system. Expect to see results after 200 miles of driving. If the leak persists, a second application may be added.
Thank you!
