Moses Ludel discusses the Jeep XJ Cherokee cooling demands.

     The XJ Cherokee came originally with a 2.8L V-6 (1984-86) or 2.5L four...In 1987, the XJ Cherokee gained the new AMC 4.0L inline six with EFI and 177 horsepower...The chassis and body remained virtually the same, however. The 4.0L engine relied upon a radiator that fit into the tight confines of the original XJ Cherokee body.

Griffin Radiator makes racing, high performance and OE replacement radiators.

     Radiator at left has been a proven Griffin high performance XJ Cherokee application with 2.5" thick core. The design requires some installation modifications. At right is the latest Griffin OEM replacement radiator with advanced technology—a high-output aluminum radiator with the option of two electric fans. Either version will readily handle the horsepower of a stroker inline six build-up! The new radiator at right is a direct fit.

     Since 1987, the XJ Cherokee's 4.0L six has gained more horsepower, struggled with air conditioning and power steering, battled off-pavement elements and taken on rock crawling challenges. All of this relies upon an engine cooling system with a low-profile radiator core!

Rebuilding a 4.0L often turns to building a 'stroker' six

     Today, owners take the 4.0L to a 4.5L, 4.6L or 4.7L displacement with the use of a stroker crankshaft. The increase in horsepower adds even more load to the cooling system...The solution is a radiator that flows more GPM or GPH (gallons-per-minute or gallons-per-hour), has more core surface area and offers more efficient materials. For a high output radiator, we turned to the latest XJ Cherokee radiator offering from Griffin Radiator.
