Why would your vehicle be getting hot after you replaced the thermostat?

first of all, do you have the right thermostat? ie: winter, summer. if so i would get the radiator checked, it may be getting pluged.

about 30$ to do it yourself, maybe less.

Was the gasket replaced? Have you checked the hose and the heater core. Is everything tightened down?

The thermostat is stuck open and needs to be replaced.

Would need to know if car was overheating before waterpump and thermostat was replaced.

not really. the only thing i would change though is the thermostat. Try to get a lower opening temperature thermostat.

Usually this is not the case. It looks like a bad thermostat, because no way the coolant is not getting hot, but a rusted up thermostat would not open for the coolant to circulate. If I were you I will change the thermostat first than check the water pump.

because the water pump is not working properly....

I would have to assume that you need to replace your thermostat. If the temp. gauge isn't getting very hot (around 190 degrees) after the vehicle has been runing for an extended period of time the thermostat is probably stuck open.

Year, make and model would help us help you.

Assuming it did not overheat before you replaced thermostat and water pump you may have installed the thermostat backwards. It is also possible the cooling system wasn't refilled properly and was air bound.

Yes it can cause it to overheat but first check your thermostat. That would be the 1st cheapist thing to do before you did anything else. I got an 85 regal(overheating) and the thermostat or the heater core is the problem im getting them both replaced tomorrow and will let know of how it runs.

This question is not complete. . Need to know if you've replaced radiator, thermostat, hoses etc. Are you asking this question *after* yo checked the thermostat, changed, added or drained the system?

thermostat first, then gasket then thermostat housing cover. I'm having trouble getting mine to seal properly. any help would be wonderful

Ingeneral, the fan will run only if the temperature of the radiator is above the normal range. If the fan is running, then the radiator must be over temp unless the radiator fan thermostat or it's relay is defective. If the radiator truly is over temp then you have a larger over-heating problem You state the thermostat was replaced. if you replaced the fan thermostat then either the radiator really is over temp and it…

Either the thermostat is set too high on the hot water heater or the thermostat is becoming faulty and boiling the water too high which would mean you need to get it replaced.

It would depend on what vehicle you have but generally it is located very close to the thermostat housing in most vehicles.

Could use more info about the vehicle but a good place to start would be to replace the thermostat.

The thermostat control engine temperature. If it fails the engine can run hot or cold - that would happen long before over-heating caused the engine to stall.

It is not as simple as just taking the miles off. If you would like an older vehicle to have 0 miles on it you would have to have many parts on the vehicle resurfaced and replaced.

If the thermostat is broken in the closed position the engine would overheat rapidly. If it was broken in the open position the engine cooling system would not reach normal operating temperature and the heater would produce only warm air. Take the thermostat out and put it in a pan of water on the stove. When the water gets to around 200 deg F, the thermostat should open. If it doesn't it needs replaced. Observe…

Did you put the thermostat in backwards? I would check to see where the steam is coming from. I had to change out small hoses for the same problem with mine.

Maybe you need a freon boost.

Water pump not pumping or a pluged radiater

It's probably not getting heated coolant to the radiator. Check the heater control valve and the control on the dasboard.
