Garage Cabinets, Garage Storage, and Garage Organization

Hi!

I have a SL500 and I noticed that when my heat is off my car runs at normal temperature, but once I turn my heat on it slowly decreased the guage down to cold. I shut off the heat and it will go back up to around the middle of the guage (normal setting).

I do get heat when the guage is at its normal place. I changed the thermostat and the gasket and refreshed the antifreeze. My car has over 72,000 miles (mostly highway traveling for work).

What else can I do? Any suggestions would be greatly appreciated.

Thanks!

i doubt its still your thermostat causing it maybe got stucked open. have you looked under and check for leaks?

sad to say this but all i could suggest is to bring your car to a qualified air-conditioning service shop and diagnose your problem.

please update us here if you have found the culprit. thanks in advance. good luck lukasito and welcome here in the forum.

Well, indeed a strange phenomena. Are you sure, that a correct thermostat is installed ?? who installed it, and what kind of thermostat is it ??
