odd temp problem

[highlandgst]

So my temp gauge after my car warms up sitsi nthe middle ( normal) but mainly in low gears because of quicker spooling when my car started to boost the temp drops and I don't mean alittle I mean it goes way down but after i blow off and stop accelerating it goes back to normal .... so new thermo ? or other problem ?

The temp goes down because of the water pump spinning and pushing that much more water as the engine rpm goes up; but yes, sounds like a slow thermostat.

I have the opposite problem with my TSI. After the car warms and I slam the throttle she almost overheats, I checked the fans and only one is working. Any advice on what's causing it not to work?

I would start by checking the wiring. You can test the fan itself by using two jumper wires. I was having a problem on my 1g with the fan switch so I hardwired them in to the ac switch. I think if you have dsmlink you can enable the fans to run constantly. If one is working I couldn't see it overheating to bad.

Ok thanks for the advice, I just checked my belts as well, the alternator belt is worn badly, I will replace that as well. Is it possible that has something to do with it? Thanks for the help!
