How Often Should Coolant Be Changed on a Semi Truck?

Coolant is an essential part of keeping a semi truck running efficiently and safely. The coolant helps to keep the engine from overheating and can prevent costly repairs. It’s important to know how often to change the coolant in your semi truck, as this will ensure that your engine runs optimally for years to come.

Why Change Coolant?

Coolant helps to lubricate the engine components and allows heat to dissipate away from the engine. Over time, the coolant will become contaminated with dirt and debris, reducing its ability to properly lubricate and transfer heat away from the engine. When this happens, it can cause the engine to overheat and damage internal components.

How Often Should You Change Coolant?

Most experts recommend changing your semi truck’s coolant every two years, or every 24,000 miles (38,000 km). This should be done even if you don’t notice any issues with your truck’s performance. If you are unsure when you last changed your coolant, it’s best to get it checked by a professional.

Tips for Changing Coolant

  • Make sure you use only approved fluids for your specific type of semi truck.
  • Always use protective gear such as gloves and safety glasses when working on a vehicle.
  • Check all lines and hoses for any signs of wear or damage before replacing them.
  • If possible, have a professional mechanic inspect your vehicle before changing the coolant.
