Assuming your car is an OBD-II M44, the stock thermostat spec. is 95*C. There are, however, any number of things that could cause it to run hotter, including: air in the system, deteriorated water pump impeller, clogged radiator, clogged water jackets in the head/block, etc. If the temp. is noticeably fluxuating when the A/C kicks on and off, something isn't quite right. Does the temp needle noticeably move as well, or is it just on your OBD monitor? |
