Technical details
Renew these while the system’s open
Any time you replace a compressor, renew the wear parts and set the oil — it protects your new compressor and your warranty:
Accumulator / drier
Always replace the drier with the compressor so moisture and debris don’t reach the new unit.
Shop driers →Expansion valve / orifice
Replace the metering device so refrigerant flows correctly and debris is caught.
Shop metering devices →PAG oil & UV dye
Set the correct PAG charge for your system and add UV dye to catch future leaks fast.
Shop oil →Fit it right
A new compressor fails fast if the system isn’t flushed and the oil isn’t set. Do it in order:
Recover & flush
Recover the charge, then flush the system to clear debris from any prior compressor failure.
Replace wear parts
Fit a new drier and metering device, and new O-rings at every connection you open.
Set the oil
Measure and set the correct PAG oil charge for the system before install.
Evacuate & recharge
Pull a deep vacuum, then charge to the vehicle’s R-134a specification.
