Question about 2003 Volkswagen Golf

3 Answers

VW Golf 2.0 is overheating after replacing thermostat.

Yesterday, my 2.0 overheated. I got it home, replaced the thermostat today, refilled the coolant, and it is STILL overheating. I have noticed that the two front fans aren't coming on like normal. Are there fuses that work these fans? Are the fans even the problem?

There is a strong possibility that the impellers on the waterpump are broken!!!!. they are made out of plastic and are notorious for breaking. ck this first have seen it countless times. make sure new waterpump has metal impellers.

    the waterpump must be removed for inspection. it is timing belt driven, so def. replace the belt while in there too. and ck tensioners and wheels. with the addition of those parts, the bill at a shop could be in the $4-500 range all said and done. this is routine maintanance at 105k.

If engine is overheating, first check and see if you have coolant, add only when engine is cool. If this does'nt work get engine up to temp. then turn on the inside heater if cool air comes out then you most likley will need to replace the water pump.

Your radiator's core may be constricted with rust particles/debris. Clean and flush the radiator with a heavy duty cooling system cleaner. You'll need to remove the thermostat temporarily and follow the directions on the label.

Hold the dealer accountable, for starters! It could be the thermostat, a coolant leak, a severe engine problem, who knows? You shouldn't have to concern yourself with diagnosing and fixing a car you bought yesterday, unless you bought it as-is.

I am having the same problem. I have read that only a GM thermostat may work aftermarket thermostats dont work in some cases. If the top radiator hose is hot and the bottom is is dramatically cooler, then more than likely, the thermostate is not opening. The other part I dont know yet is how to purge the system of air. Trying to find that out now. Good luck.

Sounds like you have coolant leak if you are loosing coolant or a bad thermostat. I would replace the thermostat, they run about $10. The other fan is an aux fan and will only run when the a/c unit is on.

this sounds like a thermostat fault, but also could be the sensor switch to the radiator but is more likely the thermostat, it should be located at the front top of engine, follow the top water hose to the engine and you will find the thermostat housing, also just a heads up, these had a problem when first made, according to the known fixes and problems with VW's the hoses corroded inside and started loosing water, this could be wise to get the system presure checked to...hope this helps

Sounds like you may need a new Thermostat.

Get a Haynes or Chilterns manual and a new Thermostat for the carfrom a car parts place like Autozone. Its normally a simple opperation to change it.
