REPLACEMENT
Note. If a component is replaced, add an appropriate amount of compressor oil. When replacing the compressor, the new compressor will already have the specified amount of oil in it. Install the new compressor after removing the same amount of oil that is remaining in the compressor removed.
| Replacement parts | Amount of oil replenishment |
|---|---|
| Evaporator | 114 milliliters (3.9 US fl oz, 4.0 Imp fl oz) |
| Condenser | 7 milliliters (0.24 US fl oz, 0.25 Imp fl oz) |
| Hose | 1 milliliters (0.03 US fl oz, 0.04 Imp fl oz) |
