Hello Gents,
I have very confusing heat issue in my car! I have noticed a month ago my cabin is kind of hot, but I was thinking maybe because of summer season. Any way, 2 weeks ago, I was in my car idling for about 20 min when my AC compressor shut off and hot air started to come out from cabin vents.
So I checked that AC, all ok. Freon is within range, compressor sound is normal, condenser ok, and fans ok too.
Coolant level is full too.
So just today I plugged in the obd2 and checked all temps!
Outside temp is 104F, and kept my car idling for 20 min, AC on. Here is what shocked me!
Coolant temp was stable all the time at 194F
Intake manifold temp kept rising so fast within 20 min reached 194F !!!!!
That's crazy hot, I have never seen this much anytime before!!!
My car have UEL exhaust with full heat wrap, OFT stage 2, Misimoto dual fan and shroud, and have oil cooler..... its been this way for 5 years did not change anything!
what could be the issue ? all temps are normal range, except for really crazy intake air temp
