NLXTACY
Wits' End
I have been plagued with overheating issues for half a dozen years now. The truck has always been on the higher side of comfortable. I have now done everything under the sun to try and mitigate the issue to no avail!!!!!
Today was the straw. Its currently 110º outside my house here in West Hills, CA. As you can see from the image, the truck is now at 234º. Its typical temp, when its over 100º out, is 213-217º. I really don't know where else to go with bringing the temps even into the warm range that most SC owners deal with. My truck is just too damn hot. I'm all ears guys. Here is the long and short of what I've done so far (all under 30k miles):
• Truck as327k 334k miles on it. Engine was completely and expensively rebuilt at 298k:
