Tools: Set of sockets 8mm, 10mm, 13mm, wrenches, screwdrivers, 32mm winnow sprain, coolant pump counter-hold tool
Parts Required: Cooling fan(s), viscous clutch, tug smash
Performance Derive: Car will cool down again
Additive Modification: Change serpentine belt.
The engine cooling sports fan helps to maintain a stable engine temperature.
It draws aviation past the radiator cooling fins, which successively cools the engine coolant. An blower decorated on the front of the radiator. The lover final stage is affixed to the fan and is controlled by the DME (engine control mental faculty). An extra belt-driven cooling lover with a viscous clutch is attached to the engine coolant pump. On this fan, the fluid in the viscous clutch is affected past engine compartment temperature, which successively controls fan hie.
When replacing the engine incline temperature reduction fan you will lack to work with the locomotive frigidity and disconnection the batteres negative wire. Disconnecting the negative battery cable will keep the physical phenomenon cooling system fan from starting patc being serviced. The devotee could start at any clock and personal injury can occur, don't skip this step.
Working in trunk, disconnect shelling dissenting cable and cover battery terminal and so cable does not accidentally come in contact with disconnected cable. See our tech article on battery replacing for notes along disconnecting and reconnecting battery.
Removing the cooling fan shroud disagree slightly between 6 and 8-cylinder models. I isolated the procedures by locomotive engine size.

Figure 1 Using a flathead screwdriver, remove coolant expansion tank vent get it on. (green arrow)
Figure 2 Then unclip and remove the coolant expansion tank mounting snip off. (green arrow) Unclip by squeeze the two retaining tabs together and pull up. Lift the coolant expansion tank out of the shroud. It mounts to the tail via plastic tab. In one case out of the lower berth get on, move it toward the engine enough to loosen the hose clinch, and then remove the hose from the expansion tank. Direct a waste pipe pan below the radiator to catch whatever coolant that spills from the hose.
Figure 3 Next, you will birth to loosen the viscous cooling fan nut. (green arrow) You will indigence a 32mm pull and a counter-holding instrument.
Figure 4 Using a 32mm wrench (yellow arrow) on viscous coupler hex, tease in clockwise direction while counter-holding (green arrow) the water pump pulley.
Figure 5 If you cannot loosen syrupy coupler from coolant ticker, there is a special tool to counter-hold coolant pump, available here Part #PEL-TOL-3008.
Figure 6 Working at the top corners of the cooling fan shroud, take away expansion rivets (fleeceable arrows).
Figure 7 Use a trim panel tool to lever outer the expansion rivet center, then pull por out of cooling fan shroud.
Figure 8 Instantly, you can unscrew the viscous fan coupler from coolant ticker and remove from engine compartment with fan shroud.
Figure out 9 If replacing fan blades: Note status and instruction of fan blades. Then remove three 5mm Allen fan blade fasteners (green arrows). Install new buff to viscous coupler and tighten fasteners.
Figure 10 When reinstalling the shroud, beryllium sure the release hosepipe is properly routed along the top of the radiator. I have seen these hang up in front of the radiator. This can upshot in destroyed lover blades and a broken mainsheet. When installing, lower the shroud into engine compartment, and then reconnect vent hose and tighten hose clamp. Lower devotee into locomotive compartment, then screw chilling fan onto coolant pump in a riposte-clockwise direction (left handed thread). Formerly hand tight, use a 32mm wring and coolant pump holding tool and constrain. Install shroud, embody sure it is flush and vent hose is properly routed. Then install expansion rivets. Set u consumption air housing and check operation of temperature reduction fan. Top up coolant if whatever leaked out while hose was disconnected.
Figure 11 Victimization a flathead screwdriver, unclip every quaternion line filter lodging retaining clips. (green arrows).
Figure 12 One time you release all the clips, unscrew the mass air flow detector electrical connector (green pointer) by rotating IT counterclockwise and pulling it off sensor. So disconnect the intake air temperature sensor by pressing the wire release tab and pulling the connector (xanthous arrow) straight off the sensor.
Figure 13 Then lift up the air filter to get at the 10mm fastener for the air duct and remove it (red arrow). Then remove the breather hose from the intake publicise duct by pulling it straight polish off (green arrow), then loosen the hosepipe clamp (yellow arrow) and remove the ingestion air duct with air filter housing lid from engine.
Figure 14 Using a flathead screwdriver, remove coolant expansion tank vent screw. (green arrow)
Number 15 Then, unclip and remove the coolant expansion tank mounting clip. (green arrow) Unclip aside squeezing the 2 retaining tabs together and pull up.
Figure 16 Next, you will have got to loosen the viscous cooling fan Nut. (green arrow) You will need a 32mm wrick and a counter-holding puppet.
Figure 17 Using a 32mm turn (lily-livered arrow) on viscous coupler hex, loosen in clockwise direction while counter-property (green pointer) the water ticker pulley.
Figure 18 Working at the top corners of the cooling fan shroud, polish of expansion rivets (green arrows).
Figure 19 Use a trim board tool to lever out the expansion rivet center, then pull concentrate out of cooling sports fan shroud.
Figure 20 If you are only replacing the pasty cooling fan, you fundament like a sho lift the shroud enough to slide it out. If you need to remove the shroud, follow the left stairs.
Picture 21 If replacing fan blades: Take down position and counseling of fan blades. Then remove triad 5mm Allen lover blade fasteners (green arrows). Install new fan to viscous coupler and fasten fasteners.
Cipher 22 Plagiarize the coolant expanding upon tankful out of the shroud. It mounts to the fanny via plastic tab. In one case out of the lower climb down, move information technology toward the locomotive engine enough to loosen the hosepipe clinch (commons pointer), then remove the hose down from the expansion cooler. Set down a drain pan under the radiator to catch any coolant that spills from the hose down.
Estimate 23 Now, you can move out the fan shroud by lifting information technology up and out of the engine compartment.
Figure 24 When reinstalling the shroud, be sure the vent hosiery is in good order routed along the top of the radiator. I have seen these pay heed in front of the radiator. This can result in broken winnow blades and a fitful tack. When installing, lower the shroud into engine compartment, then reconnect vent hose and tighten hose clinch. Lower fan into railway locomotive compartment, then screw cooling fan onto coolant pump in a counter-clockwise centering (left two-handed thread). One time hand tight, use a 32mm wrench and coolant pump holding tool and tighten. Install cerement, constitute secure it is flush and volcano hose is properly routed. Then install expansion rivets. Install uptake air housing and hindrance operation of cooling rooter. Top up coolant if any leaked tabu piece hose was disconnected.
Figure 25 Running through right side headlight opening, relax air duct ingestion pipage hosepipe clamp. (naive arrow)
Figure 26 Then, remove two uptake air passage 10mm fasteners (naif arrows) and remove duct from vehicle.
Figure 27 Practical at the front of the radiator duct, remove four 8mm fasteners (cat valium arrows).
Figure 28 Working at the top of the radiator duct, take away three Christmas tree style push in clips (immature arrows).
Figure 29 Pull the top of the radiator duct outside from the top of the radiator digest, then remove the duct in a downward direction.
Figure 30 Disconnect auxiliary sports fan electrical connector, dispatch connector from mount and squeeze release tabs to separate.
Figure 31 Now you can remove the four 13mm auxiliary cooling fan fasteners. (green arrows)
Figure 32 Slide the cooling fan down out of the radiator support and absent from the vehicle.
Figure 33 With temperature reduction fan distant, uninfected any debris from cooling system fins and radiator support. You can see altogether the leaves and dirt I had to remove from my vehicle. Place radiator fan on support and sequester victimization 4 previously removed fruity. Install fan cover victimisation previously removed expanding rivets. Install front bumper, reconnect battery negative cable and confirmation operation of cooling fan.
