overheating is back

[rsteinmetz70112]

Reading the last post something occurred to me. Have you checked to see if it actually running hot? Is it simply a gauge error?

Different situation but I once had an English car when for some unexplained reason once the car warmed up the temp gauge went to the peg, if the headlights were on. If you turned the dash lights down the gauge went down as well. The engine was not running hot.

Yah, I thought of that too. That's why I plan on replacing the sensors again eventually. Too many other pots on the fire to worry about it right now though.

Do you have a ScanGauge, or some other OBDII reader that you can hook up to the car (either of you)? That way you could get a temp reading off the ScanGauge and bypass the dash gauge to see if it is reading correctly or not.

I do have a scan guage ... but it's in the RV. Last time I hooked it up in the 'Clips, it turned off my speedo. Wierdest thing I ever saw. I'll give it a shot though, now that the hot weather is here, it may give some interesting results.

But, if the sensor is bad the scan gauge will still give a bad reading since the scan gauge will still be getting its signal from the bad temp sensor.

Very true Billy. Didn't pay attention (nothing new there) to the fact that we were talking about the sensor and not the gauge itself. If just the gauge is bad then the ScanGauge will read correctly if the sensor is bad then everything will be all cattywhumpus.

I'm thinking the sensor that turns the fan on/off (not the sensor for the guage). When the AC is on, the temp is rock solid where it's supposed to be. I got the sensor from the stealership but it looked different (not as long). There has to be a reason that a longer probe is better!!!

I could be wrong (it happened... once) but I don't think I've ever heard the electric fan come on without the A/C. I wonder if it would help if you wired in a manual switch for that fan to force it on.

Sorry,

This thread has gotten long & it was 2 pages ago, I'm talking about overheating issues on my Eclipse (which has 2 fans). Everyone else is talking VX. Just sharing lessons learned.

BTW, VX fan should be 'OR'. It should come on for engine temp OR with A/C.

I thought I was wrong once... But I was mistaken
