Engine Cooling problem
2000 Ford F250 V8 Two Wheel Drive Automatic 142000 miles
'I have a 2000 F250 Crewcab P/U. We have an issue where the truck spikes to overheating, we stop, turn the truck off and restart. Then it doesn`t overheat again. The problem is very random and seems like something is blocking the waterflow. We have replaced the water pump, thermostat, lower hoses, flushed the radiator 3 times and the problem still exists. 1 more fact, twice I have just let off the gas or put the truck in nuetral and I watch the temp automatically drop back to normal. We are at a loss as to what to try next.'.
