If you haven't been paying attention (ie-reading my other threads) my '86 900S is running hotter than usual, with the temperature guage getting to about 3/4 or so in stop-and-go traffic, while running at the usual 1/2 mark on the highway.... usually the car always ran at 1/3 to 1/2, with me virually never remember seeing the guage over 1/2.
To test I just started the car and let it idle, the fans (both) finally kicked in with the guage between 5/8-3/4, once the fans started, the guage immediately dropped to just over 1/2, where it stayed. Before the fans started, with the guage at 1/2, i felt the upper radiator hose and it was warm to the touch (not HOT, just slightly more than warm), so i assume i'm getting coolant to the radiator (how much is unknown, but at least some).
So, it seems to me that i need the fans to start spinning at a lower temperature. Where is the sensor that reads the temperature, is it in the switch itself, and therefore buying a new 82 degree switch SHOULD fix my problem? Is there still potential that the thermostat is bad?
Lastly, when i put on the A/C button both fans kick in, but i hear a "ZZZZZPPFFFTTTT" when i push in the button, sort of sounds electrical in nature. I couldn't tell for sure because i wasn't able to have somebody else push the button while i listened in the engine compartment, but it sounded as if it was coming from the A/C compressor. Is this normal, and if not, can anybody diagnose what could be going on?
Thanks for the tremendous help from everyone, i've been posting more b/c i'm starting to "tinker" more (not sure if that's such a good thing or not!)
