I've done a compression test and it's good.
New thermostats installed.
New waterpump installed.
New radiator installed. (Previous owner used stop leak)
Bypassed heater core to see if it was a clog issue didn't change anything
Put in a dual fan setup from a parts car cause mine only had one fan. Flushed the engine with a garden hose got gunck out then ran clear water for like 5 min.
I noticed fans don't stay on long.
It over heats when driving not at idle.
Any idea what it could be. I hooked everything buck up right and their still no hot air out the vents internally. Oil looks fine. No bubbles in radiator.

Could be more stop leak clogging up some of the water passages

What's the coolant level in the reservoir doing? Bad headgasket? The last 7th gen I had could idle for hours without any problems but if I drove it 2 miles down the road the reservoir was almost overflowing. It was a bad headgasket.
