We knew keeping the 2.5L four-banger cool behind the CJ vintage grille and still being able to run a rear driveshaft would not be easy. Luckily we know the right place to look for a narrow and reliable aftermarket cooling fan. Flex-a-lite! After talking with the folks at Flex-a-lite they convinced us that its TJ electric fan (PN 160) would flow enough air while being narrow enough to fit. A quick tip that we had to use is to remove the bulb seal from the front of the shroud to gain more space. There is about 1⁄2- to 3⁄8-inch between the water pump pulley and the fan.
