1. Clean the area around the breathers. Remove the breather from the front axle.

2. Wash the breather in clean nonflammable solvent. Wipe the breather dry and check the breather for damage.

3. Install the clean breather back into the axle. Replace the breather if the breather is damaged.

Note: Make sure that the slot in the breather is parallel to the axle housing.

If new belts are installed, check belt adjustment after 30 minutes of operation. For multiple belt drive applications, always replace the belts in matched sets. Replacing only one belt of a matched set will cause the new belt to carry more load because the older belts are stretched. The additional load on the new belt could cause the new belt to break.

2. Inspect the condition of the serpentine belt. If the belt is worn or frayed, replace the belt.
