How do I make a claim? Email Thermagasket@gmail.com with: your order number, your email, vehicle year/make/engine, the symptom you had, the date you installed it, confirmation that you followed the instructions, and a photo or short description of the result.
Will it work for my engine? A sealant can't fix every engine failure. If your engine has major mechanical damage, such as a seized engine, a sealant is not the right fix. Not sure? Email us your vehicle and symptoms before you order.
What is a blown head gasket?
It is a breach in the seal between the cylinder head and the engine block. This often happens during severe overheating when parts warp.
The gasket fails under high pressure. Exhaust gases then escape into cooling or oil ports, causing the engine to overheat further.
What are the symptoms?
Visible steam from the tailpipe is a common sign. Some minor leaks show no visual indicators and require a gas check in the cooling system.
You may also see a milky white emulsion under the oil cap. This indicates water in the oil, which increases head gasket leak repair cost.
How does Thermagasket work?
Breaches create "hot spots" reaching temperatures 3 to 4 times normal levels. Thermagasket reacts to this heat instantly.
The metallic alloys form a high-temperature seal. This deflects heat away from the patch and preserves the long-term integrity of the repair.
