Mazda 2: Refrigerant Pressure Switch
REFRIGERANT PRESSURE SWITCH REMOVAL/INSTALLATION
1. Disconnect the negative battery cable.
2. Collect the refrigerant. (See REFRIGERANT CHARGING).
3. Remove the ground from the engine mount No.3.
4. Remove the air cleaner installation bolt and slide the air cleaner component aside.
5. Disconnect the refrigerant pressure switch connector.
CAUTION:
- If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and abnormal noise will occur. Always immediately plug all open fittings after removing any refrigeration cycle parts to keep moisture or foreign material out of the cycle.
6. Remove the cooler pipe. Do not allow compressor oil to spill.
7. Loosen the refrigerant pressure switch using two spanners.
8. Remove the refrigerant pressure switch. (See Refrigerant Pressure Switch Installation Note).
Tightening torque
- 9-10 N*m {92-101 kgf*cm, 80-88 in*lbf}
9. Install in the reverse order of removal.
10. Perform the refrigerant system performance test. (See REFRIGERANT SYSTEM PERFORMANCE TEST).
Refrigerant Pressure Switch Installation Note
1. Apply compressor oil to the O-rings and connect the joints.
REFRIGERANT PRESSURE SWITCH INSPECTION
1. Install the manifold gauge.
2. Disconnect the refrigerant pressure switch connector.
3. Verify the high-pressure side reading of the manifold gauge and continuity between the terminals of the refrigerant pressure switch.
- If the continuity is not normal, replace the refrigerant pressure switch.
