AC Compressor with Clutch - Mitsubishi Eclipse, Galant, Endeavor (OE MR513474)

AC Compressor with Clutch for the Eclipse, Galant, and Endeavor

This is a complete AC compressor with clutch, OE number MR513474, built for the Mitsubishi Eclipse, Galant, and Endeavor with the 3.8L V6. It's a full unit, not a rebuild kit or a clutch-only part, so if your air conditioning has stopped blowing cold, or the compressor is making a grinding or squealing noise when the AC clicks on, this is the whole component you'd be swapping in.

A dead AC compressor is one of those repairs that doesn't get put off very long, mainly because there's no comfortable way to ignore it once summer hits. It's also, unfortunately, one of the more expensive parts on the AC system, so it's worth getting the right one the first time rather than guessing.

What This Compressor Actually Does

The compressor is the heart of the AC system — it takes low-pressure refrigerant gas from the evaporator and compresses it into a hot, high-pressure gas that then moves through the condenser to release heat and turn back into liquid. The whole refrigeration cycle depends on the compressor doing this reliably, and the electromagnetic clutch on the front is what lets it engage and disengage from the engine's belt as needed, rather than running constantly. When the clutch bearing wears out or the internal compressor components fail, you either lose cooling entirely or start hearing it complain every time the AC kicks on.

OE and Cross-Reference Numbers

This compressor is built to OE number MR513474, and also cross-references to 2021599AM, 6511500, 7511500, 77493, 78493, CO 10773T, and 6512196. If any of those numbers match what's stamped on your old compressor, you're looking at the right part.

Vehicle Coverage

This is confirmed for the Mitsubishi Eclipse (2006-2010 with the V6 3.8L, and 2012 across all engine options), the Mitsubishi Galant (2004-2009 with the V6 3.8L), and the Mitsubishi Endeavor (2004-2008 and 2010-2011, all engine options) — all with the 6-groove pulley configuration. If your Eclipse or Galant has a four-cylinder rather than the 3.8L V6, this isn't your compressor, so it's worth confirming your engine and pulley groove count before ordering.

What's in the Box

One complete AC compressor with the clutch assembly already attached. You won't need to source a separate clutch or transfer one over from your old unit.

A Word on Installation

AC compressor jobs aren't just a bolt swap — the system has to be properly evacuated and recharged with refrigerant afterward, and in most places that means either having the right recovery equipment yourself or having a shop handle that part even if you do the physical swap. It's also smart to check the condenser and receiver-drier (or accumulator) for contamination if the old compressor failed internally, since metal debris from a dying compressor can circulate through the rest of the system and cause a repeat failure if it's not flushed out. Wikipedia's air conditioning article covers the refrigeration cycle this compressor is part of, if you want the broader mechanical picture beyond just this one component.

Why This Is Worth Doing Right

A compressor that's undersized, mismatched, or missing the correct pulley groove count for your accessory belt setup either won't engage properly or will put uneven load on your serpentine belt. Matching the OE and cross-reference numbers above against your existing compressor is really the only reliable way to be sure you're getting a part that bolts up and runs the way the original did.
