Overheating of a diesel engine can be caused by anything that decreases the efficiency of the cooling system. Low levels or loss of coolant, poor air flow through the radiator and a defective thermostat are just a few of the problems that could cause a diesel engine to overheat. Continue Reading.
On the highway, the car may reach temperature, opening the thermostat. Now the water is also going through the upper and lower radiator hoses and radiator. If there is a small leak in the hoses or radiator, that would cause overheating, now that the water is leaving the engine, (and is under pressure). A pressure test of the cooling system usually will show a leak. Especially if you notice fluid under the car after driving. A weak lower radiator hose could collapse at highway speeds but not lesser speeds around town. The most likely cause is a plugged radiator.
