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.

  4. 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.

    1. 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).

  5. I have a 2000 Mazda 626. The car recently over heated and we have a blown head gasket so we used the blue devil head gasket sealer Hester day and let it set all day today. Would the car be safe to drive across town by tomorrow?

  6. 78 Ford Bronco. 400 V8, 80,000 miles. Rear main seal leak only when running, using 1qt. in 400 miles. Spark plugs clean, engine runs fine. If trying Blue Devil Rear Main Seal Stop should I stay away from synthetic oil? David

      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.

      Thank you!

    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!

    1. 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!

  9. 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?

  10. 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?

    1. 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!

  12. 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?

    1. 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!

  13. 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?

    1. 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.

      Thank you!
