Re: Water Pump Cooling Fan Removal: 05 4.7L...
what special tool are you talking about. that could possibly help jacob.
But before we get into that, according to my 07 manual there isnt any special tools needed.
A centrifugal water pump circulates coolant through the water jackets, passages, intake manifold, radiator core, cooling system hoses and heater core. The pump is driven from the engine crankshaft by a single serpentine drive belt.
The water pump impeller is pressed onto the rear of a shaft that rotates in bearings pressed into the housing. The housing has two small holes to allow seepage to escape. The water pump seals are lubricated by the antifreeze in the coolant mixture. No additional lubrication is necessary.
Both heater hoses are connected to fittings on the timing chain front cover. The water pump is also mounted directly to the timing chain cover and is equipped with a non serviceable integral pulley
The water pump on 4.7L engines is bolted directly to the engine timing chain case/cover.
A gasket is used as a seal between the water pump and timing chain case/cover.
The water pump can be removed without discharging the air conditioning system (if equipped).
1. Disconnect negative battery cable from battery.
2. Drain cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE). Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse.
WARNING: Constant tension hose clamps are used on most cooling system hoses. When removing or installing, use only tools designed for servicing this type of clamp, such as tool 6094. Always wear safety glasses when servicing constant tension clamps.
CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If replacement is necessary, use only an original equipment clamp with matching number or letter.
3. Remove accessory drive belt (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELTS - REMOVAL).
4. Remove lower radiator hose clamp and remove lower hose at water pump.
5. Remove seven water pump mounting bolts and one stud bolt.
CAUTION: Do not pry water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.
6. Remove water pump and gasket. Discard gasket.
1. Clean gasket mating surfaces.
2. Using a new gasket, position water pump and install mounting bolts as shown. . Tighten water pump mounting bolts to 58 N•m (43 ft. lbs.) torque.
3. Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.
4. Connect radiator lower hose to water pump.
5. Install accessory drive belt (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELTS - INSTALLATION).
CAUTION: When installing the serpentine accessory drive belt, belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction.
6. Refill cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).
7. Connect negative battery cable.
8. Start and warm the engine. Check for leaks.
