I can be ok for a week , and then needle starts to go to the red and sometimes comes back down again very quickly , but sometimes goes into the red and stays there. Any ideas ?

Try putting a new battery in it and see if that helps

SOURCE: Thermostat on 2002 Chevy Impala

the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00

Hi lfortunato,

Try the radiator cap, if that doesn't work check your interior heater controls.... as you've already pressure tested, it sounds unlikely to be the pump..... If it was defective it would have leaked with that pressure. The thermostat may also cause the problem, if it's stuck open....

2006 Equinox. Losing water. Over heats. Is this a thermostat or water pump problem??


Depends on where the coolant is going.
If it is an external leak it could be a leaking water pump. If there are no external leaks and you are loosing coolant, it could be a blown head gasket. Especially if the engine has already overheated once.
A sticking thermostat would cause the engine to overheat and then loose coolant from the overflow tank. But not until it overheats.

I have a 2001 525i bmw and have replaced thermostat and hoses but car still overheats when driving and coolant doesn't seem to pass through to engine. Could it be water pump? SUGGESTIONS PLEASE?


possibly water pump, air block. maybe the radiator is blocked. maybe it is time for a cooling system service. If problems persist

Does the fan cut in when it should?

Common sources are: hose fittings are loose-look for leakage signs, radiator cap not tightened, water pump shaft seal leaking, gaskets around water pump, thermostat, radiator cooling tube(s) leaking from damage (stones, debris).

Overheating concours deville 1999, changed thermostat, new coolant, no leaks, water pump seems fine


Change thermostat new coolant , no leaks you have a head gasket, Your car is a reverse flow cooling system. This is one of GM biggest blunder they put out. You can try a radiator at least and make sure the cooling fan comes on when its suppose to.But there is no way around this the vehicle is sensitive to overheating and once that happens it over you will need a head gasket

Ok on my 95 bmw 525i I had a hole in radiator hose and repaired it but my bmw still overheated. Replaced thermostat and it still overheats. Fan comes on but top of hose is hot. After a few mins. of driving...


You should make sure there is no air in the cooling system. With the engine COLD open the bleeder screw, take the cooling cap off, make sure it is full, put your mouth on the neck and blow until a clear stream of antifreeze comes out the bleeder. Then close the bleeder, top up the coolant, and you should be good to go, unless there is another problem.

1995 BMW 525I over heating issue. I repaired head


Hi, Sounds like you have tried about everything. Ok the aux. coolant switch is for the electric pump for the heater core will not cause an over heating condition just a longer warm up of the heater core. Has the cooling system been bleed properly if there is a trapped air pocket it will not let coolant circulate. Was the new thermostat installed correctly? They have a vent that needs to be towards the top or they trap air on the back side and cant take an accurate reading to open and close. Other areas to look at would be proper operation of the fan clutch, if they fail they can cause the fan to not lock up properly and supply enough air movement through the radiator. The aux. electric fans and their temp switches do you hear them coming on are they coming on at the right temp.

Hi i have BMW 525i 2004 from time to time when


It is very important that the engine not overheat! The head can crack and this would be very bad.
I think your car is too new to need a new radiator.
Make sure the coolant level is correct.
Check the thermostat housing for leaks.
When the engine is hot, check if the fan clutch is locked up and actually driving the fan. Turn the engine off and grab the fan and try to turn it. It should turn stiffly. If it spins freely the fan clutch is dead.
It is possible that the water pump impeller has failed, especially if it is a plastic one.

What would cause my 2002 zx2 to overheat ?


Faulty thermostat, failed water pump, inoperable radiator fan, low coolant due to leak, faulty radiator cap, leaking head gasket, low oil, major exhaust leak near front, exhaust blockage, or incorrect ignition timing. If there is crust around radiator cap, cap is leaking. How long does it take to overheat? If it runs smoothly when cool, and all fluids are at correct levels, you can rule our head gasket, radiator cap, and ignition timing. If it overheats very quickly and fluids are correct, it is probably thermostat or water pump. If it seems to do better at higher speeds, it is probably radiator fan. You can check this by allowing vehicle to run in Park with hood open. Monitor engine temp on dash. When it is at or slightly above normal running temp, radiator fan should come on. Also note exhaust sound. If it seems loud and overheats gradually, you may have a leak before the converter. If the exhaust sounds quiet, but exhaust manifold is getting extremely hot (may glow red), there is probably a blockage. There will also be OK starting and idle but poor acceleration if exhaust is partly blocked.
