Overheating all the time can be a sign that your heavy-duty truck is overdue for maintenance. The oil could be dirty and increase the engine’s heat, and the coolant could be too low. Midlane Truck & Trailer Repair would be happy to inspect the engine of your truck to find out why the temperature is on the continual rise. We are going to list below common problems that will make the engine overheat.
Faulty Thermostat
The coolant is released into the engine by the thermostat. The average lifespan of a thermostat is 10 years. If the thermostat malfunctions and does not open the coolant valve, your engine will overheat because it will not have coolant circulating through it. Replacing the faulty thermostat with a new one will solve the problem and reduce your engine’s temperature.
Faulty Water Pump
The water pump accepts the coolant from the thermostat and pushes it through the engine, hence the “pump” in its name. The water pump tends to go bad after you have put 100,000 miles on your heavy-duty truck. The same is true with the pump as with the thermostat. If it’s faulty, you won’t have coolant in the engine. Consequently, we will need to replace the water pump.
Clogged Cooling System
Mineral deposits, dirt, and sludge can also clog the cooling system over time. This is why a cooling system flush and refill is recommended every 30,000 miles. This allows us to remove the deposits so the cooling system hoses do not get clogged. If the hoses are clogged, or if the radiator is clogged, the engine will overheat when you drive your heavy-duty truck.
Leaking Cooling System
The same is true with a leak in the cooling system. Whether the coolant is leaking from the hoses, seals, gaskets, or the radiator itself, when the coolant leaks out of the system the level of coolant is reduced. Consequently, the engine will run hotter because it doesn’t have as much coolant circulating through the engine. We can find the leak and repair the problem.
Radiator Problems
Finally, the coolant circulates through the truck’s engine and then returns to the radiator where it is cooled down by air inlets and a fan. If the air inlets get clogged with dirt, the coolant will remain hot. If the fan breaks down, the coolant will remain hot.
