116* yesterday :eyebulge: on my drive home from work. Azusa & Duarte mountain side was on fire close to the 210 fwy. News reported a fatal crash up in Azusa Canyon which started the fire.
My air/fuel mixture, cylinder head temps and inlet air temps were all about the same as yours on Saturday and Sunday. I actually had air inlet temps as low as 79 degrees on the Coast on Saturday, but once inland, they rose as high as 150. I had a high cylinder head temp of 230, but it only was up that high for a minute or two.
Only up to 95 F for me so far...but I am in Michigan!
As an aside, Ford validates their cars to survive at over 120 F...climbing a 9% grade...at GVW+10%. GM and Ford also drive through downtown Vegas during rush hour trying to overheat the car at 120 F with full sunload. You should expect good cooling performance in rush and stop traffic well above that temp...especially with just 1 or 2 people on board.
