What happens if the thermostat on my car is not working?
The circulation of the coolant is blocked. So, the coolant cannot get to the radiator to be cooled. As a result, causing the engine to overheat. The consequences of an “open failure”; may be less catastrophic than those of a “closed failure”. So, if your engine has overheated for any reason, replace your thermostat.
Can a thermostat cause an engine to overheat?
A thermostat can cause engine overheating in many ways. It can be stuck shut, it can be stuck open, it can be partially open, it could be opening at the wrong temperature and it could just come apart and be broken. If you are overheating always check your thermostat, as it is one of the top causes of overheating.
Why does the thermostat rise when the engine is running?
While the engine is running the coolant temperature slowly rises. As a result, making the thermostat begin to open. The opening allows warmer coolant in the engine to flow into the radiator.
Why is my water pump and thermostat not working?
The radiator, water pump, and thermostat are definite possibilities, but there are a few others that are possible also. A faulty cooling fan is the first thing that comes to mind, but it could also be a head gasket issue, clogged coolant passages inside the engine, or faulty radiator hoses.

What happens to the thermostat when the engine is cold?
The flow of coolant does not cycle through the radiator unless it is hot and needs to be cooled. When an engine is cold, the radiator fluid is cold, so the thermostat is in the closed position. In this position, coolant will only flow in the engine.
