Inspection Speedometer 1. Adjust the pressure of the tires to the specified level. 2. Drive the vehicle onto a speedometer tester. Use wheel chocks (A) as appropriate.
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.
Description A/C pressure transducer convert the pressure value of high pressure line into voltage value after measure it. By converted voltage value, engine ECU controls cooling fan by operating it high speed or low speed. Engine ECU stop the operation of compressor when the temperature of refrigerant line is so high or so low irregularl
