Aluminum Coolant Radiator For 2001-2004 Jeep Grand Cherokee 4.7L V8, OE CU2336

A Coolant Radiator for the Grand Cherokee

This is an aluminum coolant radiator built for the 2001-2004 Jeep Grand Cherokee with the 4.7L V8 and automatic transmission, cross-referenced to part numbers CU2336 and 52079883. If your Grand Cherokee's temperature gauge is running hotter than normal or you're topping off coolant more often than you should, this radiator replaces the complete unit as a direct fit.

Why This Generation of Grand Cherokee Is Prone to Radiator Issues

The WJ-generation Grand Cherokee's 4.7L V8 pairs with a radiator that also handles cooling duty for the automatic transmission fluid, since this radiator includes a built-in transmission oil cooler rather than a separate unit. That dual role means the radiator's internal passages see more total heat load than a radiator handling engine coolant alone, which is part of why these radiators tend to develop internal corrosion or seam leaks as they age past the 100,000-mile mark. Combined with the plastic end tanks aging and becoming more brittle over time, it's common for a Grand Cherokee this age to need a radiator replacement even if the rest of the cooling system is in otherwise good shape.

Compatibility

Fits the 2001-2004 Jeep Grand Cherokee Laredo, Limited, Overland, Special Edition, and Sport trims with the 4.7L V8 engine and automatic transmission. Because this generation of Grand Cherokee was also offered with a 4.0L inline-six and a 3.7L V6 in later years, it's worth confirming your specific Grand Cherokee has the 4.7L V8 before ordering, since the other engines use differently sized radiators.

Signs Your Radiator Needs Replacing

A failing radiator on this generation of Grand Cherokee typically shows up as a temperature gauge that climbs higher than normal, coolant that needs topping off without an obvious puddle underneath, or in more advanced cases, a milky discoloration in the transmission fluid, which can point to a failed internal cooler letting coolant and transmission fluid mix. Because that kind of cross-contamination can damage the transmission if it goes unnoticed, checking both fluids periodically on a Grand Cherokee this age is worth the few minutes it takes.

Why Replace the Complete Radiator

Once the aluminum core has developed internal corrosion or the built-in transmission cooler has started to fail, there's no dependable way to repair either issue without replacing the radiator as a whole, since both the coolant and transmission fluid passages run through the same core assembly. Installing a new radiator means both cooling functions start fresh, which matters given how much a failed internal transmission cooler can end up costing if it's allowed to contaminate the transmission. Replacing the complete unit up front is generally far less expensive than the transmission repair that can follow if a failing internal cooler goes unnoticed for too long.

Installation Notes

Replacing this radiator means draining the cooling system, disconnecting the upper and lower radiator hoses along with both transmission cooler lines, removing the radiator's mounting brackets and fan shroud as needed, and lifting the old unit free before installing the new one in reverse order. Because this radiator includes a transmission cooler, flushing the transmission cooler lines before connecting the new radiator helps prevent old debris from contaminating the fresh unit.
