Problem with temperature? - 7/4/2008 6:25:48 PM

My 2001 Passat is doing something weird. WHen driving around at speeds of 80 km per hour or less, the temperature stays at 90 degrees Celcius, which is right in the middle of the guage. Anything 90 km per hour or over, the guage jumps to 130 degrees (redlie). Then I get the stop alarm with the temperature signal flashing.. When I slow down to 80 or less, the guage immediately drops back down to 90. I''m thinking this is a sensor or something. Any help would be great. Thanks!

So your suggesting my pump isn''t pushing the coolant through the engine anymore? If that''s the case, would my temperature still jump back down to 90 instantly when I slow down? I only ask because that is what it''s doing.

no it will turn at lower rpm
but at higher speeds it stops
take the small line off the resivor and watch it flow then have someone rev the car up to 3000 rpms and see if the flow stops or slows down
