Part# 475 JEEP WRANGLER FAN II (Nylon Shroud)

INSTALLATION INSTRUCTIONS

1987-2003 4 & 6 cylinder Wranglers

REMOVE OLD FAN & SHROUD

1. Remove rubber splash guard (if so equipped) at

bottom of fan shroud.

2. Remove 4 screws holding shroud to radiator, and

remaining screw holding power steering

reservoir. Tuck reservoir out of way temporarily.

Save all bolts. (Note: Shroud will not come out until

fan and fan clutch are unbolted.)

3. Remove four nuts holding fan and fan clutch

assembly to water pump hub. Remove fan clutch

assembly in one piece, along with old shroud. Do

NOT remove water pump pulley. Replace nuts

onto water pump hub and tighten.

Assemble new fan unit

1. Press plastic control knob onto the thermostat

shaft on Flex-a-lite fan shroud.

2. Screw left and right end brackets to fan as shown

with 3/8" bolts and flat washers supplied. Do not

tighten yet. See FIG. 1.

INSTALL NEW FAN UNIT

1. Lower Flex-a-lite electric fan unit into place. Fan will squeeze between radiator hose and power steering

reservoir. Be careful not to damage radiator core with mounting brackets during install.

2. Hold fan in place and, using original shroud bolts, fasten through new brackets and into original mounting

points on radiator flange. The power steering reservoir locates in its original

position.

3. Making sure that rubber seal contacts radiator all around, tighten 3/8" bolts holding

fan to brackets.

.

NOTE: 1997 AND UP Wranglers were produced with one or more fluid tanks mounted directly to the original

fan shroud. The shroud will be discarded in this installation. 4-cylinder models will require a Reservoir Bracket

Kit, Part# 30927, 6-cylinder models will require a Tank Bracket Kit, Part# 30928, to complete your installation.
