i've read alot of these old threads...here's my dilema,at idle the car never goes above the R,but once driving it goes wayyyy past that,from what i understand its normal for it to be on around the M before the fans kick on. in my case someone wired directly to the cabin fuse box a small aftermarket fan,single speed. if i come to a stop with the car on it will eventually cool down to about the M. i also noticed that the air the fan is pulling from the radiator is cool,shouldnt it be hot if the temp gauge is so high? normally i'd say the engine has bad headgaskets,only it doesnt show any of the normal signs, oil isnt chocolate milk colored,coolant appears to be of normal color,no gunk build up in the overflow tank or rad cap. one more thing,shouldnt the coolant in the overflow be hot if the cars running that hot? because its not even warm. could it be that the fan is too small? i'd say its got a 12" diameter,and doesnt spin all that fast. i know i need to get a real guage w/numbers to know for sure just how hot the car is actually getting. so my next question,what sensor can i remove to install the gauge? and were is it? thanks in advance.
