Why is my thermostat not cooling my house?
Another possible cause is a poorly calibrated anticipator. You can try to lengthen the cooling cycle by moving the anticipator arm in single-notch increments toward the marking for “longer” on the round dial.
What happens when coolant is never in the radiator?
This will only add insult to injury! When coolant never has a chance to give up heat via the radiator, it gets hotter and hotter, especially if you’re stuck in traffic. And even on the open road, coolant never has a chance to park in the radiator long enough to give up heat energy to the atmosphere. Never operate your engine without a thermostat!
Why does my car coolant fan keep coming on?
As you may know the coolant fan switch helps to maintain the proper coolant temperature by turning on and off at specific temperature thresholds. When this switch is not working properly, this can cause the fans to come on intermittently, all the time or sometimes not at all.
Do you need a fan behind or in front of the radiator?
Some folks believe more fans are better. But that isn’t completely true, either. You don’t really need a fan both behind and in front of the radiator. Ideally, you will have a fan behind the radiator that provides cooling capacity based on coolant temperature.
What happens if your engine thermostat is too hot?
Thermostat, that fits in Toyota A, E, S and C engines. What Does the Engine Thermostat Do? If a car’s engine is too hot, it can actually warp and become damaged. But, when it’s cold, it doesn’t run efficiently. So, it is important to keep the engine at the right temperature, which is where the thermostat comes in.

What happens when the thermostat does not open?
When the temperature rises to the number you recorded in step #6, the thermostat will start to open. If it does not, or if it doesn’t open until reaching a different temperature (hotter usually), then the thermostat is bad and should be replaced. If it opens at the designated temperature, then the thermostat is just fine.
Where does the thermostat housing meet the radiator?
The thermostat housing is right where the radiator hose meets the engine housing. It looks like half of a metal baseball. When the thermostat becomes stuck, it is reasonable to simply replace it. Also, when the thermostat housing is removed, the housing gasket should be replaced even if you’re just checking it.
