Truck Coolant System Repair Services in Myerstown, PA

Coolant Systems Explained

As a fleet manager, it's essential to know how your light-, medium-, or heavy-duty diesel trucks' coolant system works.

The coolant system's primary function is to regulate the engine's temperature and prevent overheating, which can cause severe damage to your engine. Coolant systems work by circulating a mixture of water and coolant fluid through your engine block, radiator, and water pump, absorbing the heat generated by the engine. The heated coolant then moves to the radiator, where it's cooled by air passing through the fins, aided by the radiator fan—a component that is activated at slower speeds or at a higher workload to compensate for the lack of air intake. Once the coolant is cooled down, it circulates back through the engine to start the process all over again.

A well-maintained coolant system can increase the lifespan of your engine, improve fuel efficiency, and reduce costly downtime. At Diamond Fleet Service, we offer comprehensive coolant system repair services to ensure your fleet is running better than ever before.

Coolant Systems: Common Problems, Symptoms, and Repairs

Is your engine overheating? This is a telltale sign that there’s something wrong with your coolant system. Issues range from a malfunctioning fan clutch, a clogged radiator, or a failing water pump, to a more common problem like contaminated coolant. 

Regular coolant flushes are by far the most effective way to prevent complete coolant system failure. We recommend you follow your trucks owner's manual for your coolant flush service interval. If you don’t have it handy, we suggest you get your coolant flushed once every 30,000 to 60,000 miles and your coolant system inspected for leaks.
