Message Well it doesn't "over pressurize while driving", the driving temps/operation seem fine...

I pretty sure now the problem is its going under vacuum when cooling down.
The rad cap is just a year old oem nissan .9 bar.
I'm going to replace that again anyway.

The car does run fine, it only overheats at idle in high outdoor
air temps, 85F or hotter. Once on the road it cools right down.

No oil in the coolant, no coolant in the oil, the car does blow
some white/blue smoke at startup/warmup, but after that it
goes away. I've tested the coolant for CO , that was negative. Compression test showed nothing.
