check the water pump
2000 Pontiac grand am se keeps over heating I changed the water pump, the thermostat, radiator cap, head, and it is still over heating. make sure thermostat is going the right way , spring gose to the motor
You could have a bad water pump causing no coolant flow, inoperable radiator fans, a coolant leak,............
Head gaskets need to be done.
Cooling fan could be faulty or radiator could be clogged or have slight leaks in it .
I am not familiar with the Audi, but on most cars, the thermostat is at the point where the top hose leaves the engine to go to the radiator. A bad thermostat can make your car overheat. If it has not been changed since 1992 it should have been changed long ago.
does the fan even turn on? my bike was over heating because i broke the fan switch on the bottom of the radiator. i ground the wire too the frame and the fan turned on and cooled the radiator down. note the fan will still run if u turn your bike off . so what i did was loosen the switch which also drains the radiator. and soldered a wire on the center pin and reinstalled it . replaced the antifreeze and now the bike runs great.
check the radiator cap, needs to be 13psi at least, i believe. that was my issue with my old ford, the cap was shot
If your radiator isnt leaking and car is having a over heating problem and coolant spewing out. Chances are your thermostat needs replaced. possible the radiator needs to be flushed. But more likley its thermostat
im having the same problem with my 1994 I've replaced the heater core,thermostat,radiator,i checked the coolant, and it's not over heating or nothing and still no heat lol
could b thermostat going, radiator cap bad or it may just be dirty/broken down coolant that needs to be changed.
The radiator may be plugged up. There are products available to help clean the cooling system, and the cooling system should be backflushed after using them.
It could be a Head Gasket, Thermostat, water pump, bad radiator or just needs coolant. start with the cheapest which is a thermostat.
