What are common issues that cause semi trucks to overheat?

Kaos Truck & Trailer Repair • 7 March 2023

When you first notice that your semi truck is overheating, you’ll want to safely pull off the road and call up an experienced mobile mechanic who can help you assess the situation and then conduct any repairs that are needed. At Kaos Truck & Trailer Repair, we provide expert roadside semi truck repair in the greater Las Vegas, NV area. Here are five common causes of semi truck overheating.


Bad Radiator Cap

With a faulty radiator cap, your truck’s cooling system may not properly reach and release pressure. A failing radiator cap can lead to problems such as a radiator seam leak or a bursting hose.


Faulty Thermostat

When a thermostat doesn’t open and close like it’s supposed to, there becomes a greater risk of overheating. A mobile semi truck mechanic will be able to conduct thermostat replacement in a timely fashion so you can get back on the road ASAP.


Failing Water Pump

When there are problems with a water pump, such as leaks or a failing impeller, overheating can occur. Water pump issues sometimes get overlooked as the cause of overheating, but they are a common source of cooling system problems.


Coolant Leak

The proper level of unpolluted coolant plays a vital role in keeping your truck running at a safe temperature. If you think your truck is leaking coolant, then you should have a mechanic conduct an inspection as soon as possible.


Blown Head Gasket

There’s definitely cause for concern if your temp gauge suddenly shoots upward and/or steam starts rising up from under your hood. In such a scenario, you’ll want to pay close attention to the area around your head gasket to see if there’s any bubbling coolant. If there is any, then you may need to replace your head gasket.
