Repairing a Blown Head Gasket

cylinder head, blown head gasket, repairing a blown head gasketRepairing a blown head gasket may be easier than you think!  When faced with either paying a huge repair bill or the ridiculous task of tearing down your motor and replacing the actual head gaskets it can seem like a much better idea to just scrap the car rather than deal with the headache of the repair.

The good news is, there is now a better option to repair your blown head gasket!  If a hard part repair doesn’t make sense on your vehicle either due to its age, the cost or other factors, you can try repairing the head gasket yourself very quickly with simple hand tools!

Repairing a Blown Head Gasket

  1. Remove thermostat and flush the cooling system
  2. Fill the system with water
  3. Add BlueDevil Head Gasket Sealer slowly to the radiator as the vehicle idles
  4. Install the radiator cap and allow the engine to idle for at least 50 minutes
  5. Completely drain the cooling system, install a new thermostat and fill the system with the correct amount of coolant

The trickiest part of this procedure is removing and reinstalling your thermostat.  The first step is to find where the thermostat is located in your vehicle. The thermostat is almost always at the end of your upper or lower radiator hose inside a housing.  To remove the thermostat simply unbolt the housing, removing the thermostat then reattach the housing.

Removing the thermostat will increase the flow of coolant through your system allowing BlueDevil Head Gasket Sealer to travel through your engine block seeking out the leak in your head gasket and sealing the leak and keeping your vehicle on the road!

  1. Did the BlueDevil head gasket sealer process after the BlueDevil system flush. During the 50 minute plus idle runtime my engine temp never got above 112 degrees and no pressure buildup in the system. The out side air temp was about 40 degrees. Will this have any effect on the success. At more than $100 in chemical I hate to loose what is in the system before it can do its job. Engine is a Chev 454, 5.5 gal sys, used 1.5 qt of head gasket sealer.

    Thanks Ken

      Thank you for asking about your Chevy. The BlueDevil Head Gasket Sealer will start to react at a temperature around 150 degrees. If the vehicle never got up to that temperature, it would not have started reacting or started sealing. Please contact our technical support line at 888-863-0426 so that we can better assist you.

      Thank you!

  2. hi BDP, I have a 2010 RAM 1500 SLT with the 5.7 hemi V8 MDS. The head gasket is blown and the Freeze plugs leak too. Im not sure about any block damage. Im looking for a quick fix and from the testimonials, it seems like I can use the BD head gasket repair kit. However, my concern is how it will do with the V8 since it is recommended only for the 4 cyls and V-6s. In addition, my current situation is that the engine turns over but does not run; In addition, when I pour coolant, it leaks through the plugs. Please could you advice what would be the best way to go about this and which BD products I need to use?

      Based on your description, we would recommend the BlueDevil Head Gasket Sealer (https://gobdp.com/product/head-gasket-sealer-38386/). The BlueDevil Pour-N-Go Head Gasket Sealer you had referenced is only intended for use in 4 or 6 cylinder engines. In order to get the benefit of using the product, the vehicle would need to be able to idle for a full 50 minutes. If the vehicle is unable to do so, unfortunately, it would not be a good candidate for the product.

      Thank you!

  4. Hi guys I was reading your articles about the product to seal the block and the gasket. But my question is, does it works in a Heavy Rigid Truck? And if yes, how many bottles I could need?.

    Any help will be highly appreciated.

    Cheers

      Yes, the BlueDevil Head Gasket Sealer is able to work on larger trucks with larger cooling systems. The amount of product you would use would be indicated based on the cooling system capacity table on the back of the bottle, below the directions. If you are unsure of the cooling system capacity, you may check your owner’s manual or contact the dealer for this information.

      Thank you!

  5. My 2000 BMW has exhaust and high pressure in the coolant . So I bought the product Car was idleing fine. Then I removed the spark plug that had low pressure and with that spark plug removed the car will not idle for 50 minutes straight it’s dying every 10 minutes or so should I leave the spark plug in place and re try the product.

      Yes, the BlueDevil Head Gasket Sealer would treat cracked heads on your Dodge Ram. Be sure to follow the cooling system capacity table on the back of the bottle to ensure the proper amount of product is used.

  7. on a 2005 Subaru forrester 2.5 sohc with front external headgasket leak , no smoke , no cross contamination, runs smooth which product to seal it up ? the pour and go or the 32 oz of the regular sealer?

      Thank you for asking about your Subaru Forrester. You may use either of the Head Gasket Sealers that we manufacture. The “Pour N Go” (16 oz./white label) is a 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 thermostat and a flush before applying the product; the 32 ounce is the more concentrated formula.
      The product with the yellow label will give you best overall results as long as you can remove the thermostat and flush the system prior to use. With the use of either product, be sure to follow the guidelines for the proper amount to use. Be sure to use the correct amount based on the cooling capacity of the vehicle.

      Thank you!
