#12738 of 12742 2004 Jetta overheating but not when idling by meef Sep 18, 2009 (7:57 am)
Can anyone tell me the next step I should take to troubleshoot my jetta with an overheating problem? It runs at proper temp when in idle but heats up when I drive it a block or two. I have replaced the thermostat, the two fans by the radiator run when its hot, i checked the small top hose going to the ball-shaped resevoir but no antifreeze comes out when idling and its cool. Now what? thanks in advance! Replies to this message: bpeebles (Oct 05, 2009 3:03 pm)

Hi all: Does anyone know how to determine whether a 2.0 engine is an "ABA" vs. an "AEG"? Can you get that from the VIN...or what? Thanks, vwdawg Replies to this message: bpeebles (Oct 05, 2009 3:05 pm) vwdawg (Oct 06, 2009 1:33 pm)

Replying to: meef (Sep 18, 2009 7:57 am) The factory waterpump with plastic impeller is known to "come apart". Once the impeller is not connected to the shaft.... it does not pump coolant like it should.   The waterpump is SUPPOSED to be replaced when timing-belt is replaced... I would expect your 2004 is close to needing this procedure anyway. The cost is the labor to get in there so you should replace EVERY MOVING PART that the timing-belt touches.   oh.... many folks have a BRASS IMPELLER waterpump installed when the TB is replaced... that is what I did.
