The Schrader valve is located under the A/C pressure sensor on the compressor discharge tube.

#### Tools Required

• | J 39500-B R-134a Refrigerant Recovery, Recycling and Recharging (ACR4) System

• | J 26549-E Orifice Tube Remover/Installer

1. Use J 39500-B in order to recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Remove the harness from the pressure sensor.
3. Remove the pressure sensor from the fitting.
4. Remove the Schrader valve from the fitting.

### Installation Procedure

1. Install a new valve to the fitting.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the pressure sensor to the fitting.

Tighten
Tighten the sensor to 5 N·m (44 lb in).
