An overheating diesel engine is more than just a nuisance; it is a warning sign of trouble to come. Below, we examine the most common causes of diesel engine overheating, as well as how to prevent them. When you need diesel engine repair, contact Integrity Fleet Service in Gilbert, AZ for the job.
In the radiator, debris, dirt, and other pollutants can accumulate over time, restricting coolant flow. When the radiator becomes clogged, heat exchange efficiency declines, resulting in higher engine temperatures. Regular maintenance, such as draining the radiator and checking for obstructions, can help prevent this issue. The radiator can also be kept clean by maintaining enough coolant levels and using high-quality coolant.
To keep the engine working at the right temperature, the thermostat regulates the flow of coolant through it, opening and closing as necessary. When the thermostat malfunctions, it may become stuck closed, preventing coolant from properly circulating and causing overheating. It may also become jammed open, causing the engine to run hotter than necessary, resulting in decreased fuel efficiency. Regular inspection and replacement of the thermostat can help prevent this.
The engine coolant maintains the engine's temperature and avoids overheating. However, leaks can occur because of malfunctioning hoses, gaskets, or radiator components, allowing coolant to escape and lowering system performance. When coolant levels drop, the engine no longer receives adequate cooling, resulting in higher temperatures and potentially overheating. Engine damage can be avoided by regularly inspecting for coolant leaks, such as puddles under the car or low coolant levels in the reservoir.
Engine coolant is transferred by radiator hoses. Radiator hoses can degrade, split, or leak after prolonged exposure to heat, pressure, and contaminants. When a radiator hose is damaged, coolant can leak out, causing low coolant levels and poor cooling system performance. Because of this, the engine could overheat and damage critical components. Examine the radiator hoses for evidence of wear, such as cracks, bulges, or soft spots.
