COMPRESSOR OIL DRAIN PROCEDURE - FIXED DISPLACEMENT
| CAUTION | Be certain to adjust the refrigerant system oil level when replacing an A/C compressor. Failure to properly drain and measure the refrigerant oil from the A/C compressor can prevent the A/C system from operating as designed and cause serious compressor damage. |
The Denso 10SRE18 A/C compressor is filled with refrigerant oil from the factory. Use the following procedure to drain and measure refrigerant oil from the 10SRE18 A/C compressor.
- Position the original A/C compressor so that the refrigerant oil can drain out of the suction and discharge ports into a suitable clean measured container. Hold the original A/C compressor in this position until all of the refrigerant oil is drained from the compressor.
- Drain all of the refrigerant oil from the replacement A/C compressor into a clean measured container.
- Refill the replacement A/C compressor with the same amount of refrigerant oil that was drained out of the original compressor. Use only clean refrigerant oil of the type recommended for the A/C compressor in the vehicle. CAUTION: Failure to properly adjust the refrigerant oil level prior to installation of a replacement compressor can prevent the A/C system from operating as designed and cause serious compressor damage.
- Install the replacement A/C compressor onto the engine. Refer to «COMPRESSOR, A/C, INSTALLATION»(ref-612707-S19078228292014043000000) .
COMPRESSOR OIL DRAIN PROCEDURE - VARIABLE DISPLACEMENT
| CAUTION | Be certain to adjust the refrigerant system oil level when replacing an A/C compressor. The refrigerant oil in the Denso 6SEU16 A/C compressor can only be drained using the procedure described below. Failure to properly drain the refrigerant oil from the A/C compressor can prevent the A/C system from operating as designed and cause serious compressor damage. |
If the Denso 6SEU16 A/C compressor is being replaced, some refrigerant oil must first be drained from the replacement A/C compressor. The 6SEU16 A/C compressor is filled with 100 milliliters (3.4 oz.) from the factory. Drain 50 milliliters (1.7 oz.) of refrigerant oil from the replacement 6SEU16 compressor. Use the following procedure to drain and measure refrigerant oil from the 6SEU16 A/C compressor.
Scheme 66
- Place the replacement A/C compressor (2) on a workbench and remove the drain plug (1). CAUTION: The 6SEU16 A/C compressor is filled with 100 milliliters (3.4 oz.) from the factory. Drain 50 milliliters (1.7 oz.) of refrigerant oil from the new 6SEU16 compressor when replacing only the compressor. NOTE: When replacing multiple A/C system components, see the «REFRIGERANT OIL CAPACITIES»(ref-612707-S23794342422014043000000) chart to determine how much oil should be removed from the replacement A/C compressor (example: new 6SEU16 compressor and receiver/drier requires 80 ml. (2.7 oz.) of oil to be added to the system. 100 ml. (3.4 oz.) of oil is in replacement compressor. 100 ml. (3.4 oz.) minus 80 ml. (2.7 oz.) equals 20 ml. (0.7 oz.) of oil to be drained from replacement compressor).
- Position the replacement A/C compressor so that the refrigerant oil can drain out of the drain port into a suitable clean measured container. Hold the replacement A/C compressor in this position until the required amount of refrigerant oil is drained from the compressor. CAUTION: Failure to properly adjust the refrigerant oil level prior to installation of a replacement compressor can prevent the A/C system from operating as designed and cause serious compressor damage.
- Reinstall the drain plug. Tighten the drain plug securely.
- Install the replacement A/C compressor onto the engine. Refer to «COMPRESSOR, A/C, INSTALLATION»(ref-612707-S19078228292014043000000) .
