How to Replace the Coolant Filter

How to Replace the Coolant Filter - Ops

2014 model year engines and earlier are equipped with a coolant filter.

  • Current engine designs no longer use coolant filters. If you have a coolant filter, you may choose to remove the filter at your next maintenance interval. For more details reference bulletin 15TS-10Rev.

Note: In addition to the cleaning procedure, other components of the cooling system should be checked periodically to keep the engine operating at peak efficiency.

Service the cooling system as follows:

Warning: HOT COOLANT

To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure.

Note: Change the coolant filter only after the vehicle has cooled and no residual pressure is present.
Note: Use care to prevent foreign objects from entering the filter housing.
  1. Place the transmission in neutral, and set the parking brake.
  2. Clean outside of the coolant filter housing.
  3. Using a 36-mm socket, unscrew cap and filter and allow the coolant to drain into the housing. After draining, remove the assembly from the housing.
  4. Remove the filter from the plastic cap by placing the filter on a solid surface and apply pressure on the plastic cap at an angle.
  5. Remove coolant filter O-ring and discard it. Lightly lubricate a new O-ring with clean engine oil and install it on the filter cap.
  6. Check filter housing for any debris and remove if necessary.
  7. Insert a new filter element into the cap.
  8. Insert element and cap assembly into the housing. Torque the cap to 55-60 N·m (41-44 lb·ft).
  9. Check coolant level and adjust if necessary.
  10. Warning: ENGINE EXHAUST

    To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic.

    Warning: PERSONAL INJURY

    To avoid injury before starting and running the engine, ensure the vehicle is parked on a level surface, parking brake is set, and the wheels are blocked.

  11. Start engine with the accelerator pedal in the idle position. Monitor all gauges or indicator lamps.
  12. Check the filter housings for signs of leakage.
