Truck Coolant Systems Repair Services in Watertown, SD

Schedule Repair

At Pete's Fleet Service, we understand the importance of proper coolant maintenance and offer a range of services to keep your truck running smoothly. The coolant system in a diesel truck is a crucial component that helps regulate the temperature of the engine and prevent overheating. This system works by circulating a coolant mixture through the engine, where it absorbs heat and then transfers it to the radiator to be cooled down. 

Fan Clutch Maintenance

A fan clutch is a key component that works by regulating the operation of the cooling fan, turning it on or off depending on the temperature of the engine. When the engine temperature is high, the fan clutch engages the cooling fan to help dissipate heat and prevent the engine from overheating.

The failure of a fan clutch can have serious consequences for the vehicle's performance and the engine. Some common symptoms of a failing fan clutch include reduced engine power, increased fuel consumption, difficulty starting and worse case, overheating. In some cases, a loud noise or vibration can emanate from the engine when the fan clutch is damaged.  

It is important to have your vehicle inspected regularly by a mechanic to identify any issues with the fan clutch or other components of the cooling system. If you suspect that your fan clutch is failing, it is important to have it repaired promptly to prevent further damage to the engine and other vehicle components.

The Importance of Coolant Changes

Coolant helps maintain the optimal temperature of your diesel engine. Over time, the coolant can become contaminated or exhausted, leading to overheating and other problems. That's why it is essential to change the coolant regularly, to ensure that the engine is operating efficiently and to extend the lifespan of the vehicle.

The recommended interval for changing the coolant varies based on the class of diesel trucks. For heavy-duty trucks, it’s typically every 30,000 miles or 2 years.  Our team will determine your service interval based on your truck class, model, usage and manufacturer’s recommendations. This simple maintenance task can help prevent serious damage to the engine and other components, and keep your vehicle running smoothly.
