Application? Radiator cooling? Slow overheat, not rapid ? Fan belt tight? Good air flow through radiator from fan? Is there an oil cooler in radiator or in line with radiator?

Customer reply replied 10 months ago
Fan belt is tight and air flow is good. This is a 1104D-44T. Can you find out if there is an oil cooler in radiator? Or in line with radiator?
Technician: Curtis B., Technician replied 10 months ago

Engine application dictates that, not the engine. What is application? Are hydraulics heating up? Do you see lines going into the bottom of the radiator ?

Engine application is a generator
Technician: Curtis B., Technician replied 10 months ago

So there is no oil cooler. Do you have a temperature gun, to test the hot points of engine/ Harbor Freight has one for Bout $25. Point at a hose and it gives direct reading. Very accurate. Then you can test drop across radiator, top and bpttom hoses and water pump.

I am in Hurricane ravaged St Thomas, and I am not a mechanic. I own the generator with the Perkins engine. It would probably take two weeks to get anything here from Hsrbor Freight. I am dealing with the gentleman from whom I purchased the generator with the Perkins engine, who is not an expert generator mechanic. I am attempting to get answers from you for him. Can you please give us a check list of items to do in hope of finding out why the engine shuts down from overheating?
Technician: Curtis B., Technician replied 10 months ago

I will assume it is full of coolant. You have no coolant loss? Try removing the thermostat, located where the top radiator hose connects to the engine . That will give better flow of coolant through the radiator. That will also let you see the water circulation in the top of the radiator. If not flow of coolant in the top of radiator , then the water pump may have bad impeller. If all checks good, do you have a manual thermometer to double check the temperature gage and sender that is shutting off engine?

OK I will pass this along to the "mechanic". I don't know if he has a thermometer. I will not see him until tomorrow, so this will have to be continued. Thanks for your help.

I saw your response but have been unable to get the generator guy over here. This is like a war zone. Nothing is normal.
