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

    1. 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!
