Circuit Diagram
Description Heated Oxygen Sensor (HO2S) consists of the zirconium and the alumina and is installed on upstream and downstream of the Warm-up Catalytic Converter (WCC).
Oil Specification 1. The HFC-134a system requires synthetic (PAG) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed. 2. Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the model of compressor.
Replacement 1. Disconnect the negative (-) battery terminal. 2. Recover the refrigerant with a recovery/ recycling/ charging station. 3. When the engine is cool, drain the engine coolant from the radiator. 4. Remove the expansion valve cover (A).
