What are common reasons that semi trucks overheat?

What are common reasons that semi trucks overheat?At the first indication of overheating, you'll want to pull your semi truck off the road as soon as you safely can. At this point, it'll be best to call up a reputable semi truck mechanic who can help you figure out if your rig can be driven any further. Here's a look at five reasons that semi trucks overheat.

Failing Thermostat

If your truck's thermostat doesn't correctly open and close, then overheating could ensue. In trucks that have never had their thermostat replaced, there's a good chance that this is the source of the overheating.

Blown Head Gasket

If white steam emerges from under your hood or your temp gauge suddenly skyrockets, then it'll be best to inspect your engine in an attempt to identify the source of the issue. You'll definitely want to check in the area of your head gasket and see if there is any bubbling coolant. If there is, then head gasket replacement could be necessary.

Faulty Radiator Cap

The radiator cap plays an important role in making sure that your truck's cooling system is able to effectively reach and release pressure. A radiator cap problem could lead to significant trouble, such a bursting hose or a radiator seam leak.

Bad Water Pump

Due to their location, water pumps often go overlooked as the cause of overheating. If the pump has a faulty impeller or has begun leaking, then there's a reasonable chance that overheating will result.

Coolant Leak

To prevent overheating, it's important to always drive with the right amount of clean coolant. There are multiple locations from which coolant might leak, and it'll be best to have a semi truck mechanic conduct an inspection to pinpoint the source of the problem.
