Your cooling system is what keeps your truck from overheating. It works by circulating a mixture of water and coolant through the engine. Over time the coolant mixture becomes contaminated with scale and rust, which can clog and damage the cooling system components. A cooling system flush essentially flushes out the entire system of contaminants and replaces the coolant mixture with fresh coolant and water.

To determine when your truck’s cooling system should be flushed, check the owner’s manual for the manufacturer’s recommendations. The frequency will depend on a number of factors:
- Engine size;
- Vehicle’s mileage;
- Age of the coolant;
- Climate you drive in;
- Type of coolant your vehicle requires.


During a coolant flush, all fluid in the cooling system is removed. A hose is attached to both ends of the cooling system and the entire system is power flushed and cleaned. Then, a new coolant mixture is pushed through the system. A flush is different from a simple drain and refill because it replaces all of the old coolant, and flushes out sludge, rust, and dirt buildup. A drain and refill entails only draining and refilling the coolant in the radiator. Flushing the coolant in your vehicle's cooling system is a great way to help maintain a healthy engine.

What are the common signs indicating you need to flush the ?

- Engine is overheating.
- Low coolant warning light is on.
- Low coolant levels.
- Coolant leaks.
- Check engine warning light is on.

The cooling system flushes will extend your engine’s life and keep you safe on the road.
