Coolant Systems

The first step in understanding how to recognize when your coolant system may need maintenance is to gain an understanding of what it is and how it works. A cooling 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). One of the primary functions of coolant is to regulate heat within the cylinder head and engine block. Coolant picks up heat and transfers it to the radiator. Coolant is also used to protect against freezing and boiling, corrosion and pitting of cylinder liners and the engine block. 

If a problem occurs in the process of dissipating the engine heat, then this is where you would begin to see equipment failure and engine issues, including engine failure. Some problems with the coolant system can include: 

  • Excessive corrosion 
  • Liner cavitation 
  • Complete engine failure 
  • Head gasket, water pump, or radiator component failure

What can you do to help maintain your coolant system?

At The Diesel Shop, we advise customers on industry best practices to maintain their coolant systems and prolong the life of their heavy-duty vehicles. Some of these practices can include: 

  • Ensuring the cooling system is filled with coolant and the freeze protection level is adequate
  • Using the same coolant already in the engine for top-ups
  • Checking radiator fluid levels and concentration
  • Properly cleaning and flush the system when coolant is changed
  • Checking the integrity of the radiator cap and looking for leaks
