Thread: incredibly hot engine bay temps, need advice or suggestions 41 Willys 350, pics insid

Well my coolant temps have remained reasonable so far, but it is currently pretty cool out so its going to be hard to say what its going to do in the summer. My biggest thing is the underhood engine temps, the thing really hasnt overheated on me except for when the relay went out for the rear fans.

I had it out in some 100 degree temps with the ac on over the summer and it stayed around 200 (that was with a large carb and a rich mixture), the stat is a 160. My concern is driven by the hot underhood temps and the leaner burn im getting from a more efficient carb. I just really want to get that underhood temp down, im going to have to take some before hand temp readings.

I found some nice little fenderwell vents that im going to cut in around where the headers are, they look as if they will blend well too. Secondly ive come up with a design to promote some air flow from under the truck into the engine bay. Thirdly im going to space the hood near the windshield an inch to help vent the heat out there. Fourth im going to build a shroud make a better shroud for around the fan that is in the engine bay. Then we shall see what happens from there.

I could run hoodless too that would take care of it all.
