Thermagasket Defender is designed for preventive maintenance in high-mileage vehicles. It is estimated that most cars with over 50,000 miles have some degree of a blown head gasket. Most slight head gasket leaks go undetected for many years, but they cause a reduction in gas mileage and performance. 

Thermagasket Defender should be run through the cooling system every 30,000 miles.

 Signs of a minor blown head gasket:

  • Steam from the exhaust once the engine is warm 

  • Coolant loss

  • Lukewarm heat or no heat from the heater 

  • Decrease in Gas Mileage

  • Sweet smell from the exhaust 

Fluctuations in engine temperature while driving. Thermagasket Defender can also be used as an extra layer of protection against Head Gasket failure on engine break-in after head gasket replacement. Head Gasket failure within the first 1000 miles after a Head Gasket replacement is a common problem that can be prevented.

Reasons for failure:

    • Faulty Head Gasket

    • Heads were not surfaced correctly

    • The gasket pinched during installation

    • Wrong torque specs or sequence

    • Reuse of head bolts

    • The cooling system was not bled correctly  

The Thermagasket Defender will seal any imperfections in the seal between the head and the block.
