Is your truck starting to run a little too hot? Does it overheat easily? Then you need to have it seen by a professional right away. Here at J & M, we can handle any type of repair your truck may need. Overheating is caused by anything that impedes the cooling system’s ability to dissipate heat. This could be a number of things. Here is a list of possible reasons your truck is overheating.

Thermostat

A thermostat is a valve that opens and closes in response to heat from the engine. When it closes, it prevents the flow of coolant, which helps speed up the warming of a cold engine. However, if it is always closed, this hampers the ability to cool the engine after it has heated. This is one of the main causes of overheating.

Leak

A quick way to check your cooling system for a leak is to perform a pressure test. If the system cannot hold pressure for approximately a minute, then a leak is highly possible. Places to check for the leak include hoses, water pump, head gasket, and the radiator, among others.

Belts

A broken or loose belt could be the culprit if you truck is overheating. Belts help to drive the water pump to keep the correct speed for coolant flow through the system. If your truck has a broken or loose belt, this reduced coolant flow could be the cause of the engine overheating.

Hoses

Sometimes the cause of an engine overheating is simply a bad hose. If a hose is cracked or has burst, this can be why your engine is overheating and needs to be fixed right away.

If your truck is overheating or just not running like it used to, be sure to bring it to us here at J & M Trailer and Truck Repair. We can find the cause of the problem, fix it, and get you back on the road quickly and efficiently.
