Default temp

Could anyone tell me what the temp is suposed to run at on my car (95 SSEi) i thought that it was idleing really hot and am wondering if a thermostat change is in order.. its hard to tell what teh gauge actually read with the tic marks going from 210 to 280, but if i had to guess i'd say it was about 225... thanks

225 does seem excessive. what conditions are you running <flat land/ hilly, temp, elevation, etc>.

The stock thermostat in your car is a 195 degree. You should run at approximately 200 degrees.

Low speed fans come on at 216 and high speed come on at 225.

If you are seeing 225, I would be checking fan operation and looking into changing the thermostat.

well i drove it about 5 min and then it was at idle in my driveway for about another 10... pretty much all flatland here in my part of michigan. about 40 Deg F outside... (not sure of elevation, maybe +600 ft...) one thing i did notice is that when i moved it to its parking spot in the driveway, all of 30 feet, the temp seemed to drop.

Sitting still you have no cooling air flowing through the radiator. Being a front wheel drive you have no belt driven fans to cool the motor, only electric at 216 and 225.

I wouldn't say that it was abnormal, however the low speed fans should come on at 216.

One other possibility is that our gauges have a slight amount of inaccuracy built in. Scanning the car for an exact temp would be good to know if there is any error in your gauge as well.

Very true. i've never owned a front wheel drive car before and it never dawned on me that there isn't a mechinacal fan on it. Good, i don't feel so worried about it any more. I'll probibly still look into putting a 180 degree thermostat into it though. Thanks for all your help!

Check that fan operation as well. I have a 95 SSEi and when I got it..temps would hit like yours. Low speed fan relay contacts were corroded and not working.

A tube of dielectric grease and removing and reconnecting 5 times on electrical components seems to be magical on the car.

I forget who said 5..but it gets the corrosion off.

Sounds normal for extended idling. I own a supercharged '92 and '93, and they both idle warm like that. Don't get your hopes up with a 180 degree thermostat, though. I installed one in each of my bonnies, and it made a little difference to the temp while the car is moving 65 MPH on the highway, but the extended idle temp remains unchanged. My gages typically read 220 to 225 before the fan(*) turn, but as someone else noted, the gage temps are a little higher than the actual temp reported by my scan tool.

These supercharged engines run hot, and a GM master mechanic told me that they're designed to run hot. This isn't comforting to know, though, when you're trying to take the family to the mountains on a summer day and you have to pull over because the temp gage is dangerously close to the red zone. That'* happened to me on both of my bonnies, and yes, both fans are fully functional and there'* nothing wrong with the cooling systems. They both have clean coolant, working water pumps (one is almost new), and one has a new radiator (replaced because the driver'* side end tank began leaking). Replacing the water pump on one car and the radiator on the other made no difference in the temp.

Billha.. with you being in *. CA I'd suggest drilling small holes in the t stat like Willwren suggests for hot climate cars.

Lash is in MI and currently has cold temps like I do. 44 degrees is about average lately.

Having a 180 this time of year puts my temps at any speed over 15-20 at 180 consistently. Same should apply with a 195, 195 should be roughly viewed until you are sitting still.

At this point with the cool temps if I mash the pedal on the highway and it downshifts I see a slight decrease in temperature before the tstat closes enough to get temps back to 180.

Yes it depends where you live. In northern states 180 deg. is a toss up in the winter.
The car stuggles to get up to temp on short trips in winter.
some change to 195 winter and 180 summer.
This is what I used to do.
