A/c Service Tips for 2002-2005
Mercury Mountaineer 4.6 V8 Gas Engine
2002-2005 Mercury Mountaineer A/C systems feature a scroll style compressor. As described in gpd Tech Tip #36, “Piston Replacement Compressors”, the scroll design is known to underperform at low RPMs and does not tolerate excess debris well on select applications.
It is best practice to properly flush the system and replace the condenser and hoses when replacing the compressor, especially after a catastrophic failure. Any contaminants/debris left in the system from the failed compressor can create a restriction in the condenser, causing high head pressure and premature failure of the new compressor.
For a hassle-free A/C service, gpd highly recommends the following when replacing gpd compressor 6511472 on a 2002-2005 Mercury Mountaineer 4.6 V8 Gas Engine:
