i just bought an 2002 passat! i have no owners manual and i have no idea whats going on, i use my a/c and everytime i do the check engin light comes on and i leak a whole bunch?? is there any idea what is going on?? also is there some special coolant i need to use??

coolant for what and what if anything are you leaking?

electric fan might not be coming on
or you could have a bad water pump

Is that what they are talking about?? I thought they were talking about the freon, or refridgerent was leaking...not too much deatil was put into that post.

yeah im leaking water! so how do i check to see if the water pump is bad of the fan?

Hi

to check if your water pump is broke - drive the car, when warmed up put your heater on, does it blow warm air? Does it blow warm air consistantly? Does it go cold, then warm etc. If it is the last one, then your water pump has sheared its impellor blades off the shaft and is literally 'dead in the water'. They are only plastic impellor blades and are prone to break, mine did, the wife's did - I changed mine/wife's when I did the cam belts. You can also check the heater matrix hoses for heat, if the pump is ok/not ok when the car warms up.

This may answer one of your problems, if the pump is determined fine, then maybe the fan could be at fault.

There you go...
