Replacing all the oil in a car’s heat pump compressor is critical for several technical and operational reasons. Let’s break it down carefully:
1. Lubrication of Moving Parts
- The compressor contains internal components such as pistons, bearings, and valves that require proper lubrication.
- Old oil may be contaminated with moisture, acids, or metal particles.
- Incomplete replacement can leave behind degraded oil, which fails to lubricate properly, increasing friction and wear.
