Between Omaha and Des Moines, 7 miles South of I80 | denny-o - 10/28/2016 05:46 We had overheating with our 4640 until we sprang for a new radiator. Now the problem on a cold day when doing light work is getting it warm. If it is "over-cooling"; then you need new thermostats. Had to change our 4440 thermostats almost yearly, because of over-cooling.(always found one of 2, that I removed, to be stuck open) Edit: My thermostat problems, happen to go away, after I rebuilt water pump and happen to find a small piece of brass, restricting the coolant flow, going back thru the by-pass hose. (found a location of #15, on this picture)   |
