The coolant light or radiator light is flashing on my jetta, the temp gage never goes higher than the middle reading, but the light comes on right after I start the car, even when it has been sitting all night and reading is 0. The little overflow tank seems to need water or coolant on a constant. Some small spots of leakage on garage floor. Any ideas?

I would check the coolant flange on the driver's side of the engine. It has a few hoses coming out of it and 2 sensors. This is a common problem on VW. If this seems OK, then have your VW cooling system pressure checked until the leak is located.

THIS JUST HAPPENED TO ME!!!! YOU NEED T O CHECK THE COOLANT FLANGE AND ALL PIPES LEADING FROM IT... JUST GOT IT FIXED NO PROBLEMS SINCE AND IT IS VERY IMPORTANT TO GET THE ACTUAL VW COOLANT BECAUSE WHEN YOU BUY THAT REGULAR STUFF THAT SAYS ALL MAKES AND MODEL IT ACTUALLY IS EATING AWAY AT THE TUBES AND IN THE LONG RUN YOU WILL HAVE TO REPLACE THEM ALLL... THE ACTUAL COOLANT IS PINK AND IT IS ABOUT 20-30 DOLLARS AT THE VW DEALER FOR COOLANT CONCENTRATE (NOT DILUTED YET) AND THE COOLANT FLANGE IS PRETTY EASY TO DO URSELF WITH A 10 MM. ITS 30DOLLARS AS WELL AND IT HAS 2 BOLT AND 2 SCREW CAN REMOVE YOURSELF. WILL TAKE 30MINUTES - 1HR AT THE MOST...GOOD LUCK
