the ECT values seemed consistent with the expected results when i tested them.
the cap is brand new FWIW, and i replaced all the hoses a year or so ago when one was cracking.
yeah, I understand that honestly but the main thing for me is that my car *doesn't* run at 208 or 200 or even 190. if I run the AC at all, it stays at 175 or lower (typically 155-160) even after long drives.
if I don't run the AC, it gets really hot (on the gauge) before it even attempts to cool itself lol.
I wish I had some way to see inside and confirm the sensor has coolant flowing on it and not an air bubble or something.
I tested my dad's car (admittedly it is newer), an 03 grand marquis with a 4.6L. watching the ECT reading on that, it went from ambient to right around 195-200 within 5 minutes very smoothly and stayed there, even with the AC running the entire time. its just weird behavior seeing mine be so slow to warm up allegedly and never hitting those sweet spots
I do appreciate everyone's assistance though, even though I'm feeling frustrated cause it feels like a "non-problem" problem
When you turn on the A/C your turning on the high speed fan. With the A/C off the low speed fan won't engage until about 208 210.
