"I have just changed the thermostats in both my 4236's because they were running cold. It has fixed one, but the other still does not go much above 130. The gauge is accurate As I have checked with a laser gun. So given the new thermostat, what else can make her run cold??? Pump not set right? Injector pump timing? (How do you set it) Injectors?
High idle is 2750 approx, she seems to pull almost as well as the port does (similar RPM loaded flat out).
I note the oil runs through the heat exchanger, could there be too much flow there? (Oil pressures are fine and both similar). The head and block are pretty cool. There is no way the water can bypass the thermostat that I can see, so she must be generating less heat then the port baby. She has a water heater loop, but I have that shut off for testing
Any suggestions?"
