How do I test my car thermostat?
Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows.

If you find the coolant is flowing, it means the thermostat valve is open.

How many nuts are in the thermostat housing?
Answer: There are only two 10 mm nuts that hold the thermostat housing (which contains the thermostat). Those nuts are easy to remove if you remove the oil filter first.
