I have a 1998 Deville, what is the usual engine temp? And what is a safe heat range for the engine? thanks TexasCadillac
This varies widely but 195-215ish.
My 99 Deville almost always runs between 199 and 205 degrees. The hottest I've ever seen it was 209 while sitting,idling, in a Houston traffic jam for over an hour in August.
My 99 DeVille is about the same as SteveHo. Rarely needs to kick in the fan.
My '97 ran a consistent 206 (summer) and 213 (winter). Cooling fans don't even come on till 224 or 225.
