just below the 90*C mark, slightly above the line if i let it sit in traffic or something.

Mine runs at 90C.. a little under halfway on the gauge, but I will be replacing it with a 180 thermostat tonight / tomorrow.. see what the gauges will read and let you all know.

P.*.
I notice you can't just go to Crappy Tire ( Canadian Tire ) to get the thermostat housing gasket.. it seems to be a dealer part only. Will post the price too when I pick it up.

The 180 thermostat part number at Crappy Tire is 14-4071-4. $5.79 CDN. That will fit on my series 2 SC engine.

Mine very rarely goes over 200. She runs 185-210 in normal conditions, the low side of that being open-air-highway and the higher end being a hot day in the states and street/city driving. Stop-and-Go traffic, she'll hit 220 but then the fans kick in. I have never seen her go over 220.

My old Bonnie never went above about 210, but my new car spends most of its time just shy of the red mark. However, I doubt the gauge'* accuracy due to the temperature jumping to an indicated 120 immediately after I start the car.

Yeah the guage is probably bad. On my bonne (RIP) The temp and batter guage would go haywire once in a while. My ran just below the redmark and but it was really running at around 200, had my mechanic check it multiple times.

canadian tire does have a part number for this. so does napa.

My Both our Bonevilles run at 200 degrees exactly almost. although, the gauge on the 95 often goes above 250.. but the car doesn't get that hot actually, had a mechanic check it. My brother'* car has a messed up oil gauge. The gauge always reads above 120 PSI whenever you put your foot on the throttle.

Really ?? Can you post it here so everyone would know what part number the next time they go to Crappy tire or NAPA... thanx

Hi I'm new here. I can see this site could be very helpful. I have a 2002 SE and I was also concerned about the temp too. It goes right up to 200F and stays there. It seemed a little high to me, I've never had a car that ran that high. Dealer says its ok. Would it be safe to put a lower temp thermostate in it our will that cause problems with the computer and all of the pollution control stuff?

I would recommend 180 thermostat.. I"ve been hearing that if you went with the 160 thermostat.. the computer will throw a SES error. 200F is fine since the stock thermostat for the car is 195F. With the stock or the 180, you shouldn't have problems with emission test.
