I'll take a Snap-on mtg2500 scan tool with 06 updated cartridges for trans, abs and troubleshooter insight, . Thanks for the appreciation, it's nice to hear.

Maybe someone else will agree or disagree with me, and if so, please chime in, as I don't want to mislead you.

As long as it doesn't go too far above that I agree he should be OK. Personally, I'd be uncomfortable with anything over 200 at this time of year but I'm in the desert Southwest and we've gotten well over 90 degrees already but thats my circumstances. I'd keep an eye on it and see what happens when the really hot weather kicks in.

Rich is correct when the ECT (CTS) is changed the internal resistance values will never be the same as the original one so there may be some deviation on the temperature gauge. The problem is the gauge cannot be calibrated by a layman.

Speaking of a Snappy MT2500 scanner and other good ones they have the capability of reading out the ECT temperature right off of the PCM module which is more accurate than the gauge.
