ON SALE NOW: $109.99 +S/H
Leaking coolant from your radiator, heater-core or engine block?
This is a non-clogging, leave-in sealer that works fast, lasts up to 4 years (32oz.).
Just pour-n-go, leave-in formula!
Not for head gasket leaks due to
curing temperature difference...
ON SALE NOW: $59.99 +S/H
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.
Over the past 18 years, Dura-Seal® has helped over half a million customers world-wide and has become the leader in automotive head gasket sealer manufacturering by offering the most advanced sealer products you can buy...

Dura-Seal
® is more advanced than other head gasket repair sealers. Our Head Gasket Repair Sealer stays flexible when cured so it expands and contracts with today's aluminum engines and lasts up to 5 years. We have a *Money Back Guarantee and provide you with a Free Replacement Warranty on all Head Gasket Repair Sealers and Oil Stop Leaks 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.
