Offering an Affordable Way To Repair Your Head Gasket

At Thermalweld - We sell a repair solution online, to repair shops and provide local mobile repair services. Our formula has been repairing head gaskets for more than 27 years. Thermalweld was once rebranded as Thermagasket from 2004 to 2010 then rebranded as Steel Seal Elite from 2011 to 2018. Since 2020 an improved formula has been developed, it is now a one part formula. With the one part formula, a head gasket can be repaired in under 10 minutes.

Why Chemical Repair Has Earned a Bad Reputation

Promises of a 99% success rate, money-back guarantees, experienced technical support, proprietary formulas, nanotechnology, pour and go, etc. these claims have proven to be substantially bogus.

A prominent brand claims it mixes a custom formula for each specific vehicle due to the different operating temperatures. This is hype, as over 95% of all gas car & truck operating temperatures are between 190f to 210f. Also their formula uses “polymers” a term that sounds very scientific but is only a catchy marketing phrase.

Some mechanics will say, it's just temporary - a Band-Aid - it won’t last - it will clog up the cooling system and mess up the whole engine. This is NOT TRUE, and definitely not true if done properly.

We supply hundreds of repair shops all over the United States who believe this the BEST product on the market. Call or e-mail for referrals in your area.

THIN LAYER DEPOSITION

Our repair process is much different and faster than any other manufacturer. The steps are simple. (No need to remove the thermostat)

Prepare the coolant system by flushing it out with plain water.
Pour in the Thermalweld.
Run the engine at 3,000 RPM’s for approximately 10 minutes. Usually, it takes less than 10 minutes to repair the head gasket.
After the repair, the head gasket will be sealed but not fully cured. To fully cure the seal, drive normally at least 4 times in the 1st 3 days. The more the better.

By running the engine at high RPM’s, thin layers of the solution are passed through the hole in the head gasket. The thin layers eventually build up until the breach is completely sealed.

Custom Formulas That Address Specific Issues

Along with the flushing appliances referred to earlier, Dave and Robert developed custom formulas specific to two particular vehicles.

One has a thinner viscosity for hybrids, particularly the Prius, which use a delicate electric water pump, and the other is for diesel engines that address the high compression issue inherent in diesels.

All of these tools speak to the system approach. It is not just chemicals.
