Repair of Heavy-Duty Truck Coolant Systems
Understanding the coolant system and how it works is the first step in being able to identify when it may need maintenance or repair. One of the primary functions of coolant is to regulate heat within the cylinder head and engine block. The coolant system is designed to circulate a cooling medium which absorbs heat from the engine and dissipates it through a heat exchanger (i.e., a radiator or cooler). Coolant picks up heat and disseminates it to the radiator. Coolant is also used to shield against freezing and boiling, corrosion and pitting of cylinder liners and the engine block.
What you can do to help maintain your coolant system:
- Ensure the cooling system is filled with coolant and the freeze protection level is adequate
- Use the same coolant already in the engine for top-ups
- Check radiator fluid levels and concentration
- Properly clean and flush the system when coolant is changed
- Pressure test cooling systems for internal or external leaks
- Verify correct factory fill coolant spec and filter requirements are being maintained
