congrats Guy!!! Being cautious is a good thing. I like the toolbox test idea. Perhaps go climb that mountain to the south of you, down by Green Valley as a test. Climbing mountains will make it generate heat. I solved most of my high temp issues simply by sealing off the input air to output air flow around the radiator. the cooling air flow was stalling at about 65-70 mph. it runs 200-210 on the freeway (8 east up the mountain goinfg to AZ) 185-195 around town. The next AX will be a good test. my engine still gets filthy really quick. under teh car is higher pressure than behind teh rear window
