When a diesel engine is pushed too hard, and if there is something wrong with the diesel engine, it might overheat. This can lead to damage to the bearings, a broken cylinder head, and pistons that scrape against the cylinder walls. Therefore, you will want your diesel truck repaired before your engine overheats and becomes damaged.

Coolant Problems

Most often,  a diesel engine will overheat because it has a problem with the coolant. Even if you have enough coolant, something can go wrong with another component of your diesel engine, and this can prevent the coolant from going where it needs to go. If this is the case, you'll need a diesel truck repair service.

The coolant needs to be checked regularly to make sure that there is no debris or dirt, and there should be no discoloration. New coolant should not be mixed with old coolant because this can lead to overheating. When adding new coolant, the old coolant must always be drained out and discarded.

A Worn Out Water Pump

A diesel engine circulates coolant with the use of a water pump. The water pump seals can sometimes wear out. A diesel repair technician will need to inspect the water pump and the water pump housing for signs that something is wrong.

A Broken or Clogged Radiator Hose

Even if the coolant is in good condition, it might not be making its way to the engine because the radiator hose is clogged or has become damaged. Your diesel repair technician can quickly see that the radiator hose is broken and will replace it.

A Broken Cooling Fan

A cooling fan is a very important part of your engine. If a cooling fan breaks, this can lead to the temperature of the engine escalating quickly. When the cooling fan is not functioning properly, this is most often the result of an electrical problem. 

A Malfunctioning Thermostat

The thermostat might not be functioning properly. This will prevent the engine from being able to regulate its temperature with the use of coolant and can cause overheating.

A diesel truck repair service will inspect your truck to find out what is wrong and will then perform the necessary repairs. In some cases, a diesel truck repair company will even visit your truck along the side of the road and perform repairs so that you can get your truck back on the road.
