My car read at about 102 to 107 degree, i dont know is it in a normal range or high.
Thank You,

Mine runs a consistent 213F. From what I have read I am on the low side.

Yes, that is normal range. 102 degrees celcius is 215 degrees fahrenheit.

Cooling fans kick on @ 225 F degree's
not sure when the thermostat opens up

Oem on the stats is 180 degrees, start to open.

I have a 95 Deville Concours and I do not have the engine temperature on the cluster.. I only have the outside temp and the desired temp ofr the AC control... Anyone know whats up with that? I would really like to know what temp my car is running, especially on hot days..

95 Concours- you would have to use the obd 1 to find out your temp.

I thought that all thermostats except maybe diesels were 192/195 degrees ?

Nope - I just replaced mine (93 ETC). OEM called for 180 deg.
The normal temperature is still about 196-226 deg in my car.
It begins to open at 180 - it needs to be hotter to fully open.

Hi. This is my first post I,m a newbie. I bought a 94 eldo about two weeks ago and thought I had temp problems when I had readings from 207 on the freeway to 223 after a long idle on the digital readout. I took it to a mechanic friend and the temp in the reservoir was 170 with a thermometer and 190 in the top hose and pump with an infrared thermom when the dash said 212 to 215. I think the readouts are from the hottest spot in the system and not indicative of overall temp. I want to thank everybody in the forums especially bbobynski I have learned a ton about my car in just a short time.

My 94 SLS was sold to me by a young mother...two kids, husband gone etc., I paid the full asking price even though the temp was showing 220 ish. No fool like an old fool. When i got it home I found that both fans turned on with the ignition...and had been hot wired to do so, always. Changing the wiring back, the fans come on with the A/C but never seem to come on with the rise in temp alone. The reading is normally 201, and 203 with A/C on, with a slight increase pulling up hills. Sounds like that might be a little cold.

I noticed 'fans on' at 225 mentioned earlier, is that good for the SLS? cos i don't think i have ever let it get that high. Do i dare put it to the test? cos i don't want to pop any difficult hoses etc.

Going off the thread i know, but when i let the tires down from 76 psi the car pulled hard right. This kid was probably one of the best car sales people around.

Sounds like your fans are fine. They come on with the a/c and come on at 225. Their turn on temp is 225. The low temps are ok also. Mine will range anywhere from 199-221, depending on the outside air temp. I have seen coolant temp get up to 225-226 while sitting it traffic on a hot day.

Tires with 76 psi? The max rating I have seen on a passenger tire is 45 psi, most of the time 35 psi.

Gotta 96 deville n* what temp is too hot ie. shut the engine down inevitable gasket failure. anyone????

07-28-05, 09:12 PM
The car will tell you when it is getting hot and when to shut it down. I think that is above 240, maybe even 250.

Mine did it at 255 the last few days of its life. Happened twice before I took it in for a rebuild. It is so expensive to do just a few things, fix oil leaks, repair a head gasket and a cracked head - it was actually cheaper to have it rebuilt.

Why do I get the feeling I'll be using my 7 year/100,000 mile warranty on the engine? :P
