water pump
Would need to know if car was overheating before waterpump and thermostat was replaced.
Water pump not pumping or a pluged radiater
The primary cause of a thermostat malfunction is corrosion. It prevents the thermostat from opening and closing as it normally would.
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?
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.
Yes a bad thermostat would cause overheating in any car. A thermostat regulates the temperature.
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 is doing what it should, or there is a problem with the thermostat-fan relay or switch. If you replaced the engine thermostat that controls the flow of coolent between the engine and the radiator, then that probably wasn't your problem and you should look elsewhere for an overheating cause. I would start by determining if the engine actually is overheating or not. If it is, I would look for coolent system problems like the engine thermostat (if you didn't replace it already), water pump, leaks, scale build up in the radiator, or blockages in the system. If the engine isn't overheating then I would consentrate on the fan, fan thermostat and relays.
Yes it can. A faulty thermostat can cause overheating which will cause coolant to be pushed out of the system.
Could be a head gasket or a warped or cracked Cylinder head.
Check all your grounds
Since you have replaced these two parts, have you checked the water pump ? With age, the impeller on the pump or bushings become used enough to reduce the flow of coolant quite a bit. This will cause over heating due to lack of circulation. Also did you flush the system to make sure that there are no blockages ? And, check the upper and lower hose to make sure they do not collapse.
no, the thermostat would have nothing to do with the car not starting.
