Can a head gasket sealer ruin a thermostat?
1.0 out of 5 starsWill ruin your cooling system and maybe engine! Do not, I repeat, do NOT use this product to seal your head gasket leak. Read the reviews, look at pictures. This will clog your radiator, thermostat, heater core, and maybe even your block!
What causes a thermostat to stick closed?
The most obvious cause is a blocked radiator, low water level, or a failed cooling fan. There are more involved reasons that include failed/ failing water pump, internal obstruction in the radiator, or the engine itself.
What does it mean when your thermostat is sticking?
Thermostats fail because they become weak, stuck open or stuck closed. When a thermostat is stuck open, coolant constantly circulates and the engine takes longer to reach operating temperature. This affects everything from performance to mileage to emissions and will ultimately take years off the engine’s life.
Should I use sealant on a thermostat gasket?
Since the thermostat in your car has a regular gasket, you can use RTV or not, at your pleasure. If you’ve had seepage issues in the past, it’s almost a given you’d use it. Even if you haven’t, it’s not going to hurt anything to use it now. If you do use it, only put a thin coat on it, covering both sides evenly.
How long does it take for head gasket sealer to work?
about 15 to 30 minutes
A head gasket sealer works when you pour it into the radiator. You run the car for about 15 to 30 minutes, with the heater and fan on high. Then the special chemicals in the sealant work via heat. They will seek out and fit in cracks and gaps in the head gasket.

How long does engine block seal last?
It depends. If the leak is mild to moderate, we’ve had customers run 10,000-50,000 miles with no further issues. If the leak is more severe, or on the edge of becoming severe, the repair might last a shorter duration. The advice we always give is to act at the first sign/symptom of a cooling system problem.
What is the best sealant for thermostat housing gasket?
Gasgacinch is my favorite. IMHO it is the best sealant to use when there is no need for super goops. It is a mild contact adhesive. In the case of your thermostat housing gasket, if your surfaces are good and clean, apply GasGaCinch to the housing and the gasket, let it tack, insert the thermostat and apply the gasket.
How do you seal a thermostat gasket?
If you’ve determined that your gasket is old and devoid of any additional adhesive backing, sealant can be useful and help you secure the thermostat. In this case, you might want to apply a very thin layer onto the gasket. Take care not to apply the sealant to the thermostat itself, but apply it to the gasket.
What should I do if my block sealer does not work?
In more severe cases, the block sealer may not work, and further evaluation, or work may need to be done. Our best recommendation would be to have your vehicle inspected for a blown head gasket and coolant leaks to determine if engine block sealer will work well for your car or if another repair is more suitable.
What happens if you put too much sealant on a thermostat?
Too much sealant can actually spill out of the thermostat groove, causing other parts that surround the thermostat to come in contact with the sealant. Unwanted dried-up sealant on parts (particularly made of aluminum) is difficult to remove and clean, and can also create other problems.
