Finally got to make a 70 mph test run in the summer heat with the new fan clutch. The fan clutch helped, but the engine is still running far hotter than it should. This test was made without the AC running because the compressor seized up. I’ll retest the radiator cap and cooling system with my Stant pressure tester. All that can be left is a mildly blown head gasket. I have the diesel head gasket test kit too. Got some homework to do.
