Close to disasterous problem: thoughts? - 5/13/2008 4:20:13 PM    RamblingMan   Posts: 53 Joined: 9/5/2007 Status: offline I've been having trouble with the temp gauge reading too cold so I was checking out the 3 sensors (coolant temp, temp guage, Condenser fans). I decided to test the coolant temp at my usual running temp and realized that my normal running temp is 180deg F but if pushed beyond idle will rise to 210deg F. At anything about 180 or with A/C on fully, the condenser fans never turn on. So apparently I'm overheating but get enough compensation from my viscous fan that I haven't blown the engine. Any thoughts? Am I not understanding something properly? RM Post #: 1

Have you repalced your thermostat? The proper t-stat is a 195F, so your trk running around 210 is normal. 230 is overheating, 250 is death. Start with the coolant level, if it is low you will not get a accurate reading on the dash. If your trk is running to cold with the proper coolant level your t-stat is bad. If your sensor were bad 90% of the time your gauge just wont work. _____________________________ If it ain''''''''''''''''''''''''''''''''t leakin'''''''''''''''''''''''''''''''' it must be empty!

RE: Close to disasterous problem: thoughts? - 5/15/2008 6:24:42 PM    RamblingMan   Posts: 53 Joined: 9/5/2007 Status: offline Sorry, its a 94 D1, 93K miles. I'm not sure if the engine is running hot or cold. The guage reads cold with coolant temp of 180. If I idle at 1500rpm with A/C on high for five minutes it climbs out of cold into the "normal range" with coolant temp of 210. The T-stat is new. So I guess I run cold too often right? What could cause this? (in reply to Disco Mike) Post #: 4

Is the viscous fan clutch locked up? Did you get the right t-stat? They sell low, medium and high temp t-stats. You want the medium one, 195F. Running to cold will kill your MPG as well as carbon up the engine really fast and bad. Are you using premium gas? _____________________________ If it ain''''''''''''''''''''''''''''''''t leakin'''''''''''''''''''''''''''''''' it must be empty! Yes, one man can change the world.

I get horrible milage, usually single digits, but 11 or 12 hwy. I replaced the t-stat with the 88deg Cel (approx 190F), its the standard one from DAP. Where have you seen the three different ones?

I just looked at AB and they too only list one T-stat and it is a 190F, maybe you got a bad one and it is stuck open? _____________________________ If it ain''''''''''''''''''''''''''''''''t leakin'''''''''''''''''''''''''''''''' it must be empty!
