Warning: Wear eye protection, gloves, and protective clothing when working on the air conditioning system. Leaking refrigerant from a damaged hose or line could cause blindness or serious skin burns.
- Park the vehicle on a level surface, shut down the engine, and apply the parking brakes. Chock the tires.
- Check the appearance of the air conditioner compressor pulley assembly. If the friction surface of the pulley shows signs of excessive grooving due to belt slippage, replace both the pulley and the drive plate. Inspect the refrigerant compressor drive belt for damage and check that the belt is set at the proper tension. Also check the tightness of the compressor mounting fasteners. For instructions and torque values, see of the Cascadia™ Workshop Manual.
- Inspect the drive plate. If the drive plate shows visible signs of damage due to excessive heat, replace the drive plate and pulley assembly. For removal and installation procedures, see of the Cascadia™ Workshop Manual.
- Using a feeler gauge, check that the drive plate clutch
clearance is within limits. See Table. for clearance
specifications. See Fig. for the checking method. If the drive plate clutch requires
adjustment, see of the Cascadia™ Workshop
Manual.
Note: Check clearance in three equally spaced places.

- Inspect the compressor clutch coil wire. Check that the connector is not damaged or loose. Replace the wire if it is damaged.
- Check the overall condition of the air conditioning hoses. Look for cracks, cuts, and abrasions on the hoses. Replace damaged hoses. For replacement instructions, see of the Cascadia™ Workshop Manual. Also check for loose fittings on all of the air conditioning components.
- Check for a buildup of road debris on the condenser fins. For cleaning instructions, see of the Cascadia™ Workshop Manual.
