Ok gents I am scratching my head a little with this one. My coolant temps have been all over the place. I noticed it last spring but have been out of town so many times for work I haven't had the time to address it. It lasted through the winter doing the same thing. I used the dummy gauge on the dash for a while before I plugged into the obdII.
If the ambient temps stayed below 40 F outside I wouldn't go above half. Which was normal for me. Actual scans correlate that to 175-185F. I really noticed it would climb when I would get off the freeway and there was a strong headwind. The coolant temp would start to climb rapidly. Well above half. 190-210 F. Not worrisome to me.
Then after winter temps sarted to go up so did the coolant. Today it really started to worry me. Temps were in the 40s but the temp would still go up to 3/4. Scan says that was 220-235F. 40 degree ambient temp combine with zero long hills and not towing seems pretty hot to me.
I immediately think a sticking thermostat. The radiator is new and burped but that is relative I guess.
I am worried the header may be pumping out a lot of heat into the bay that the coolant system may not be able to handle. The reason I think that is the intake temp is around 110-120 F at idle, which leans me to overall bay temp being high.
I have yet to add an external trans cooler and I'm sure that is contributing to the overal problem to a degree.
I haven't been able to get a reading on the transmission temp but would like to know if anyone knows what system will do that. I have an obdII scanner with the app. I also have HP tuners but the last I remember hp tuners doesn't read the trans temp on these. Which may have changed I haven't used it for a couple years now after I tuned it.
Is there another option for getting a real tranny temp? Also could the transmission heating up really heat the coolant that much and that wildly?
Fluctuating 50 degrees in 5 minutes seems crazy to me and is indicative something or collective things may be happening. Or am I wrong all together and this is normal?
