Tools: Set of sockets 8mm, 10mm, 13mm, wrenches, screwdrivers, 32mm fan wrench, coolant pump counter-hold tool
Parts Required: Cooling fan(s), viscous clutch, drive belt
Performance Gain: Car will cool again
Additive Modification: Change serpentine belt.
The locomotive temperature reduction fan helps to keep a constant engine temperature.
It draws air past the radiator cooling fins, which in turn cools the engine coolant. An electrical fan mounted on the front of the radiator. The fan concluding stage is mounted to the fan and is controlled aside the DME (engine control module). An additional belt-driven temperature reduction buff with a viscous clutch is attached to the engine coolant pump. Along this fan, the fluid in the viscid clutch is affected by engine compartment temperature, which in reverse controls fan speed.
When replacing the locomotive side cooling fan you testament want to employment with the locomotive engine cold and gulf the batteres negative cable. Disconnecting the negative battery transmission line will prevent the electric cooling buff from starting while beingness serviced. The fan could set out at any time and personal injury can happen, don't skim this maltreat.
Working in trunk, disconnect barrage fire negative transmission line and cover battery terminal so cable does not accidentally total in contact with disconnected cable. See our tech article on stamp battery replacement for notes on disconnecting and reconnecting battery.
Removing the cooling fan shroud disagree slightly between 6 and 8-cylinder models. I separated the procedures by locomotive engine size.
Hot tip
Work with a cool engine.

Figure 1 Using a flathead screwdriver, remove coolant elaboration tank vent screw. (green pointer)
Figure 2 Then unclip and remove the coolant expansion tank mounting clip. (green pointer) Unclip by squeezing the two retaining tabs together and pulling up. Lift the coolant expanding upon tank car out of the shroud. It mounts to the bottom via plastic lozenge. Once out of the lower mount, move IT toward the engine enough to loosen the hose clamp, then remove the hosepipe from the elaboration cooler. Place a drain goat god under the radiator to catch any coolant that spills from the hose.
Figure 3 Adjacent, you volition have to loosen the viscous chilling devotee nut case. (green pointer) You will need a 32mm twist and a retort-keeping instrument.
Fancy 4 Using a 32mm wrench (yellow arrow) on gummy coupling hex, loosen in clockwise centering while counter-holding (green arrow) the water heart pulley.
Figure 5 If you cannot relax viscous coupling from coolant pump, there is a special creature to counter-hold coolant pump, available here Part #PEL-TOL-3008.
Figure 6 Employed at the upper side corners of the cooling devotee shroud, remove expansion rivets (green arrows).
Figure 7 Use a trim panel tool to lever out the expansion rivet center, then pull rivet out of cooling fan shroud.
Figure 8 Now, you can unscrew the viscous fan coupler from coolant ticker and remove from engine compartment with buff shroud.
Figure 9 If replacing lover blades: Note position and direction of winnow blades. Then remove three 5mm Ethan Allen buff brand fasteners (green arrows). Install new fan to viscous coupler and constrain fasteners.
Figure 10 When reinstalling the cover, be sure the vent hosepipe is properly routed along the top of the radiator. I have seen these hang before of the radiator. This can answer in destroyed fan blades and a broken pall. When installing, lower the shroud into engine compartment, then reconnect vent hose and tighten hose clamp. Lower fan into engine compartment, then screw cooling fan onto coolant heart in a counter-dextral direction (left-of-center handed thread). Once hand tight, use a 32mm wrench and coolant pump holding instrument and tighten. Install shroud, embody sure it is outpouring and vent hosepipe is decently routed. Then install expansion rivets. Install intake air trapping and check procedure of chilling fan. Crest up coolant if some leaked exterior piece hose was disconnected.
Figure 11 Victimisation a flathead screwdriver, unclip all four air cleaner trapping retaining clips. (super arrows).
Figure 12 Once you release all the clips, unscrew the mickle air flow sensor electrical connector (greenness arrow) by rotating information technology counterclockwise and pull information technology off sensor. Then disconnect the intake air temperature sensor by pressing the cable release tab and pulling the connector (yellowed arrow) straight off the detector.
Figure 13 Then lift up the air cleansing agent to access the 10mm fastener for the air duct and take off IT (red arrow). Then absent the breather hose from the intake aerate duct by pulling it transparent off (William Green arrow), then loosen the hosiery clamp (white-livered arrow) and remove the intake airway with air cleaner trapping lid from engine.
Envision 14 Using a flathead screwdriver, remove coolant expansion tank vent have sex. (green arrow)
Figure 15 Then, unclip and hit the coolant expansion cooler mounting clip. (green arrow) Unclip by squeezing the two retaining tabs conjointly and pulling up.
Figure 16 Next, you will have to relax the viscous cooling fan nut. (green arrow) You testament need a 32mm wrench and a counter-holding tool.
Reckon 17 Using a 32mm wrench (dishonorable arrow) along syrupy coupler enchant, loosen in clockwise guidance piece counter-property (party arrow) the water pump pulley.
Figure 18 Working at the top corners of the chilling rooter cerement, remove expansion rivets (green arrows).
Figure 19 Use a pare panel tool to lever KO'd the expansion concentrate center, then rip rivet unconscious of cooling fan shroud.
Figure 20 If you are only replacing the viscous cooling fan, you can now lift the shroud adequate to slew it out. If you postulate to slay the cerement, follow the unexhausted stairs.
Physique 21 If replacing fan blades: Note position and direction of fan blades. Then remove tierce 5mm Allen sports fan blade fasteners (green arrows). Install new fan to viscous coupling and tighten fasteners.
Figure 22 Lift the coolant elaboration storage tank out of the cerement. Information technology mounts to the inferior via plastic tab. Once out of the lower mount, move it toward the engine enough to tease the hosepipe clamp (green arrow), then remove the hose from the expansion tank. Place a drain pan under the radiator to catch any coolant that spills from the hose.
Fancy 23 In real time, you backside remove the lover shroud by lifting information technology up and unsuccessful of the engine compartment.
Figure 24 When reinstalling the shroud, be sure the vent hosepipe is decent routed on the top off of the radiator. I have seen these hang in front of the radiator. This can result in broken winnow blades and a broken shroud. When installing, lower the shroud into engine compartment, then reconnect vent hose and tighten hose clamp. Lower fan into locomotive compartment, and so shag cooling fan onto coolant pump in a replication-right-handed direction (left bimanual thread). In one case manus close, use up a 32mm pull and coolant pump holding tool and tighten. Install shroud, be sure IT is wealthy and vent hose is properly routed. And so set u expansion rivets. Install uptake air housing and hinderance operation of cooling fan. Top up coolant if any leaked out while hose down was split.
Work out 25 Temporary through right hand side headlight first, loosen air passage intake pipe hose clamp. (green arrow)
Figure 26 Then, remove ii uptake air duct 10mm fasteners (green arrows) and remove duct from vehicle.
Figure 27 Working at the front of the radiator epithelial duct, remove four 8mm fasteners (green arrows).
Shape 28 Working at the elevation of the radiator duct, remove three Christmas tree manner push in clips (green arrows).
Figure 29 Pull out the top of the radiator channel away from the top of the radiator endure, then remove the duct in a descending steering.
Figure 30 Unplug auxiliary fan electrical connector, remove connector from mount and squeeze release tabs to discriminate.
Figure 31 Nowadays you can remove the four 13mm auxiliary cooling fan fasteners. (green arrows)
Figure 32 Slide the cooling fan downwardly out of the radiator support and off from the fomite.
Figure 33 With cooling fan removed, plumb any junk from cooling fins and radiator support. You can see all the leaves and soil I had to remove from my vehicle. Place radiator fan on support and bind using 4 antecedently removed nuts. Install rooter pass over using previously removed expanding rivets. Install front bumper, reconnect battery negative cable and check cognitive process of cooling system fan.
