Failed Radiator Cap

A broken radiator cap will likely prevent your truck's cooling system from properly working, which can result in increased or decreased pressure in the system. This can lead to even bigger issues, such as a bursting hose or radiator seam leak.

Faulty Thermostat

One of the most common causes of semi truck overheating is a malfunctioning thermostat. if your semi has not had its thermostat replaced, then this could be what is causing the overheating. Fortunately this is often a quick fix for a mobile truck mechanic.

Blown Head Gasket

If white steam starts rising out from under your hood, there’s a chance of a blown head gasket. If you spot bubbling coolant around the head, this is almost certainly the issue at hand.
