Common Causes of an Overheating Engine

Worn Fan Clutch

Is one of your fleet trucks overheating? If so, you may have a worn fan clutch. Your fan clutch is a critical part of your cooling system as its purpose-built to engage and disengage your cooling fan. The mechanism operates based on the temperature of your engine, meaning it doesn’t engage right away, but rather, at a predetermined temperature. If your fan clutch malfunctions, your cooling fan will fail to engage, and your radiator will be unable to dissipate heat effectively. This is one of the leading causes of an overheating engine, but it’s not the only cause. 

Damaged Cooling Fan

On the one hand, being unable to engage your cooling fan as a result of a malfunctioning fan clutch is problematic, but it’s not the only way a cooling fan can cause your engine to overheat. If the fan itself is damaged after coming into contact with road debris, it won’t be able to funnel enough air through your radiator regardless of how well it’s spinning. Not to mention parts of your cooling fan that broke off could come in contact with important coolant lines and cause further damage. At Fleet Services Group, we offer roadside assistance for issues of this variety. 

Plugged Radiators

Another common cause of an overheating engine is a plugged radiator. Over time, coolant can break down and leave sludge and debris behind, which often results in the plugging of crucial radiator lines. If this happens, your radiator won’t disperse enough heat, and excess strain will be placed on your water pump and coolant lines.
