5 Common Reasons that Semi Trucks Overheat
When you first notice signs that your semi truck is overheating, it's best to get off the road when it's safe and lawful to do so. At that point, you can call up a mobile semi truck mechanic who can help you determine if your rig is safely operable. If it isn't, then the mechanic can come to you and do what is necessary to get your truck back on the road. Here's a look at five common causes of semi truck overheating.
Blown Head Gasket
If your truck's temperature gauge suddenly shoots upward or if you see white steam rising out from under your hood, then you'll want to check your engine for signs of a problem. In particular, you'll want to check around the head gasket for any bubbling coolant, which is an indication that you'll need head gasket replacement.
Overheating can result if the thermostat does not open and close properly. This is a common problem and if your truck has never before had its thermostat replaced, then this could very well be what is causing the overheating. When this is the issue, a mobile semi truck mechanic can promptly deliver and install a new thermostat.
Failing Water Pump
Because water pumps are internal mechanisms, they are sometimes overlooked as a source of trouble. However, overheating will likely occur if the pump has a worn-out impeller or has started to leak.
Bad Radiator Cap
A bad radiator cap may prevent your truck's cooling system from properly reaching and releasing pressure. A defective cap could lead to serious problems, like a radiator seam leak or a bursting hose.
If you're not driving with the proper quantity of clean coolant, then cooling system trouble could result. Coolant can leak from multiple areas and a mobile semi truck mechanic can come to you to identify and address the leak.
