Are Mishimoto thermostats any good?

5.0 out of 5 starsPerfect operating temperature! These thermostats are awesome. Great quality built in comparison to motor craft stats. I am seeing coolant temps of: 188 at idle 190-192 on the highway and about 194-196 during a hard throttle burst – all in 105 degree ambient air temperature.

Why does my thermostat keep failing?

Sometimes the thermostat fails and must be replaced; there are four main reasons for failure: overheating, sludge, defect and age.

What happens if your thermostat stops working?

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.

Can you put a thermostat in wrong?

If your thermostat is in the wrong place it can raise your utility costs. Proper thermostat placement can make your heating and cooling more energy efficient while still keeping you comfortable.

Do I need a gasket for thermostat housing?

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.
