Dura-Seal® Head Gasket Repair Sealer is specially formulated for
your individual engine! We don't use water-glass in our sealer, so we can
customize our sealer to your specific engine's temperature at the cylinder head!
This means our sealer only cures in your engine's head gasket area not the radiator 
or heatercore. With Dura-Seal® there's no chance of clogging or curing in other areas. 
Our Dura-Seal® works with aluminum & steel and stays flexible! So if you have
a Cadillac, Subaru, Volvo, BMW, or any other engine with aluminum components
Dura-Seal® is your best choice. << Simply pick your vehicle from our list!
Dura-Seal® is the only non-silicate sealer available and doesn't turn to glass when cured! It stays flexible to expand and contract with your engine. Advanced chemistry & inherent flexibility offers our customers success rates over 98% on the first application, and average repair-life of up to 5 years...
If you don't get a "full-seal" on your first application, call us and we'll send you another free bottle to get you to the finish line,
(shipping, handling, other may apply, see terms for more).
Idle engine for 20 minutes then turn off and let cool for 20 minutes, repeat this run-cycle three times. Next, drive vehicle for 20 minutes with sealer in system. Then, drain Dura-Seal® out, (it's not required to flush Dura-Seal out, just drain), later refill with coolant and Dura-Seal® Liquid-Ice. First-time applications have a 98% success rate. Only 2% require a second *free application, (*which is covered under warranty). Typical repair-life is 5 years.
Only Dura-Seal® does not use water-glass and silicates as a base ingredient. So, you never have to worry about clogging or harming your engine when using our sealers. All other sealers on the market like; Barz, Blue Deviil, Steal Seal, Thermogazket, NanoTechnology, CRC and more use water-glass & silicates which can harm your engine...

Dura-Seal
® is simply more advanced than other brands. We custom formulate your kit to cure at your engine's temperature at the cylinder head. This prevents our sealer from curing in other areas, It can only cure in the cylinder area based on temperature. No other brand can offer you that! We have a *Money Back Guarantee and provide you with a Free Replacement Warranty if you need more sealer to then typical to achieve a full-seal, (*certain conditions like S/H may apply, see Terms). So if you don't get a full seal, call us and we'll send you another free application to get you to the finish line...
Drain coolant system and run clean water through entire system. This will remove most contaminates. If you've used a water glass/silicate based sealer prior to using Dura-Seal®, you will need to purchase our "Water-glass Flush Agent" before using our sealer.

It's not required to remove the thermostat as our sealer cannot cure or clog that area, but, if left-in, it will slow the process by restricting flow. Next, pour the Dura-Seal, and Extreme Powder Pack into the radiator, (no radiator cap?) disconnect upper radiator hose from engine and pour sealers into hose (they will flow to radiator). Fill system with water.
