The Air Conditioning system requires 236 ml (8 fl. oz.) of 525 viscosity refrigerant oil.
New 525 viscosity refrigerant oil must be added to the system when components are replaced, as follows:
a. All Compressors (drain and measure the oil)
^ If less than 30 ml (1 fl. oz.) is drained add 60 ml (2 fl. oz.) to the new compressor.
^ If more than 30 ml (1 fl. oz.) is drained add same amount that was drained to the new compressor.
b. Accumulator-Add 105 ml (3.5 fl. oz.) of new oil to the replacement accumulator to compensate for oil retained by original accumulator desiccant and bag assemblies. The accumulator should only be replaced if leaking due to a perforation, damaged O-ring seat, or damaged threads.
c. Evaporator-Add 90 ml (3 fl. oz.) of new refrigerant oil.
d. Condenser-Add 30 ml (1 fl. oz.) of new refrigerant oil.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
