Yes it is necessary to remove the alternator. Remove the hose from the black thermostat hosing. The remove the two 10mm bolts and pull off the housing.

Follow the bottom hose from your radiator to the engine block. There should be a removable flange where the hose connects, with only a couple of screws to remove. I have an earlier model year, and I think the 2004 is the same.

The best thing to do is check your library for a copy of Chilton's Jetta 2004, and you can find the how to. Changing Disk brakes is a fairly simple job for an experienced mechanic, but if you have never done it, it can be dauting. Also you can buy a copy of Chilton at many parts stores such as Advance or you can order on line.

Need to fing location of ECT sensor on a 1.8L turbo 2004 jetta

Take off the two covers on top of your engine. The ECT sensor should be on your right side of the engine. It may be either black or green and has a 4 blade connector. There is a plastic clip you slide out to replace the sensor. Hope this helps. Only takes a few minutes to replace

Volkswagen jetta over heating

hi tammy
it could be an air lock stopping the water from circulating properly i seem to recall this problem on the older VW Derby and audi 50 (same engine) there is a small bleed screw at the highest point on the cooling system that allows you to bleed this air out youll find its location in the manual

another thing to try is put a flushing agent through the system incase there are any blockages in the radiator itself

hope this helps
