So finally got it out on a real hill.. Still overheats. I was climbing sisikyou pass today and I had to pull over 4-5 times to let it cool down. 15-30 mph in 1st or 2nd and the ect was still cresting 240 and the tranny was hitting 235.
Had to pull off let it run for 30-45 minutes with the hood up. Rinse repeat.
The thermostats both got replaced last year. The ****ty kn filter box gives no isolation so when the engine heats up the filter sucks in hot air. I verified by watching on the edge insight. When I pop the hood the intake trmp drops by 20degrees instantly.
I'm in San Fran tomorrow.
Can anyone recommend a good diesel tech nearby.
That airbox has to go and I need someone to check the cooling system and possibly make some tweaks.
