Standard Coolant System - Filter - Maintenance

The filter for the standard coolant system has a container. Chips and debris collect at the bottom of the container. This procedure tells you how to do these tasks:
  1. Clean the container.
  2. Clean the filter.
  3. Lubricate the container.
  4. Lubricate the o-ring.

Step 1

Use the supplied wrench [2] to remove the filter container [1].

Remove all of the chips and coolant from the container.

Fully clean the container [3].

Step 2

Use compressed air [3] to blow chips and debris from the filter element [2].

Blow debris out of the inner surface of the filter head [1].

Find the surface [4] where the o-ring on the installed container will touch the filter head.

Fully clean this area.

Use a towel that is soft and clean.

caution: Make sure to clean all debris from this surface. Debris causes leaks.

Apply a thin layer of silicone grease [5] to the clean surface.

Step 3

Fully clean the o-ring [1].

Fully clean the o-ring groove [2].

Examine the o-ring.

If the o-ring is cracked or broken [3], replace it.

Apply a thin layer of silicone grease to these areas:

  • the o-ring [4]
  • the o-ring groove [5]
  • the threads [6] on the filter container

Put the o-ring into the o-ring groove.

Make sure the o-ring is installed tightly in position.

Step 4

Align the filter container with the filter head [1].

Carefully turn the filter container with your hand into the head.

caution: Do not use the wrench [2].

Turn the container until it is tight.

Loosen the container 1/4 of a turn.

Press COOLNT to start the coolant system.

Monitor the filter head for leaks.

If the filter has leaks, do steps 1-4 again.
