Okay heres my dilema... I run a full race manifold, which means a full size rad will no longer fit. Im now running a fluidyne half rad.
Where do i begin. I constantly have to fill up the rad, and my overflow bottle is full to the brim constantly pissing out into the street. After filling up the rad, and doing street tuning for an hour, the water temp was consistant at 180deg and the car was not over heating at all. Then on the way home much later cruising at 60 on the highway, water temp and stock temp gauge skyrockets. This happens on a daily basis.
Pulled the car over near a walgreens, let the car cool down... Get some water at walgreens, pop the cap off on the rad itself. Bone dry? My water pump is fine, the stat is brand new nor is it upside down, and my headgasket is mint, nor are there any leaks in any off the coolant lines.
The system has two coolant caps, one on the stat.housing, and one on the rad itself. The rad cap is 16psi, and the cap on the stat housing i am unsure of, it could be higher. Do you think two different pressured caps could be causing this issue? Higher pressure on the stat housing causing all the coolant to escape to the overflow and not reach the rad?
Should I just have the cap on the rad welded shut or wut? Or just make sure i have two caps matching in pressure. I mean little shit like this is driving me crazy. I know the half rad will never cool as well as a full but, when shes not overheating due to what ever the problem is, she runs consistantly cool no problem
