I know this has been asked before, but I have searched and not found anything I haven’t tried. First the details, 88 XJ, 4.0l, auto, 231/300 doubler, 30/44 w/ 4.10 gears and lockers, 33” Truxus. I swapped to a 2-core GDI open rad. about 3 years ago. 195* T-stat works. Hoses are good, no spring in the lower hose. New water pump. I have hood vents and the back of the hood propped up ¾”. I have the tranny going through the rad. and a cooler. The clutch fan is bad and will be replaced this weekend. Now the problem, when I drive on the highway the temp climbs to 220 plus. I have to turn on the heater to bring the temp down. Driving around town w/ the temp at 90* plus. I have to have the A/C or elec. fan on to stay at 210*. I have not actually over heated where water spits out or gone to the red on temp gauges. (I’m running two temp. gauges. The stock one at the back of the block and an after market one at the t-stat housing.) Is there any thing else I could try? The next thing I might try is a single core alum. rad. And maybe remove the two lights in front of the grill.
