- Getting old. Sold the ranch. Sold the tractors. Moved back to the city.
Engine is overheating after about 10 minutes of operation. Coolant coming out of the radiator overflow. Temp gauge in the red.
I thought the crud on the radiator that was severely restricting the airflow was the cause. Cleaned the radiator thoroughly. Checked airflow with a piece of paper. It was sucked firmly to the fins across the entire radiator so I don't see any airflow restriction.
Replaced the thermostat and the temp gauge. Can see the thermostat open by watching the gauge. So that seems OK.
Can't see any water flow with the radiator cap off and the thermostat open.
With the engine off, tugged on the fan belt to see if the water pump bearing is bad. Couldn't get the belt to move, so it looks like the bearing is OK. No leakage visible around the water pump shaft or engine seal.
Anyone out there know a good way to backflush a Perkins diesel? The backflush kits at the auto parts stores are set up to splice into one of the heater hoses. No heater hoses on the MF-135.
Could be a bad head gasket. Anyone out there used one of those $25 combustion gas leak testers (the ones with the liquid that changes color in the presence of carbon monoxide, etc. exhaust gases in the coolant system)? Are they any good?
