Just something I have noticed over the years, people seem to pin point all the problems of higher temperature to either the water pump or thermostat..... While people always over look the simpler things....the radiator cap and fan clutch.....the springs on radiator caps wear out and the seal cracks.....the fan clutch throws its oil and doesn't lock up at the right temperature.....


Can't let this one go. The radiator cap has nothing to do with coolant temp. it only increases the boiling point of the coolant.
