It sounds to me like the water isn't circulating, due to either a defective circulating pump or a slack belt failing to drive it. You should be able to check for circulation by removing the coolant / expansion tank filler cap when the engine is cold and looking inside, where there should be a little stream of water coming through that thin pipe near the top and going down into the tank.

Hope this helps you a bit. If it does, a "Fixya" rating would be much appreciated. If it doesn't
help you, I'd be grateful if you didn't bother with a rating at present - they can't be increased later if I do manage to solve your problem! Just come back and tell me what you found. Cheers, D

One thing that affects both the cooling system and the a/c is the cooling fan.
Could be a bad fan motor or relay. Or a connector.

2000 jetta 2.0 gas - 15-20 sec after starting car the water temp alarm goes off; 60 sec later turns off. car runs fine and temp gage reads normal. Any ideas?


Have you checked the coolant level in the overflow tank? Make sure it's to the proper level. The coolant warning system can lose its little brain on the VW's. Sorry I can't be more helpful.

2000 jetta doesn't blow cool or cold air out,of the a/c.


yes, after 9 years it needs to be recharged. Have a shop with a good reputation do it. Dont go cheap. It should hooked up to a machine so you can see how much leaked out,and test for leaks. shouldnt be more than $100

sounds like your cooling system isn't full.  with the heater on Hi refill the cooling system and bleed it until all the air comes out.  Sometimes you need to raise the front of the car.  And there may be a bleed screw on the thermostat housing.

After I drive around 30 KM, my 2000 Jetta VR6 's temperature goes up from 90 deg to alarm.


First when it has cooled down, check the water level in the radiator. Then determine it overheats while idling, does the fan turn on?
