Quick update on the overheating issue...first thanks to all the input and suggestions. I installed my homemade bypass restrictor and the Hayden # 2840 fan clutch. I have since towed my 32 ft. camper a couple of times and the issue appears to be fixed. Both times I was towing in some pretty hilly country. One hill was about a 7% grade for almost 4 miles and others pretty close to that. The weather both times was pushing 90 degrees and she tickled 215 degrees a couple times but never really went much above that. Before it would push close to 225 ! Now I need to figure out how to get a little more power out of her without braking the bank or major reconstructive surgery. Ideas,,,?
