Replace water pump


Well the bad news is if you have the 3.5 liter engine, the entire engine assembly needs to be removed in order to change the water pump. If you happen to have the 3.3 liter engine you will need to remove the timing belt in order to get at it. Need to know what your engine size is before I can help any further

  • Tools Required
  • J 43651 Water Pump Holding Tool
  • Remove the thermostat housing.
  • Remove the water pump access plate from the front cover.
  • Remove the right hand fender liner.
    1. Important: A drain plug has been provided at the bottom of the water pump assembly for additional coolant drainage from the engine block and water pump.
    Drain the coolant from the water pump using the plug at the bottom of the pump.
    1. mportant: The water pump holding tool supports the sprocket and chain during water pump service. The tool must be used or the balance shaft must be re-timed.
    Install the J 43651 into position.
    1. Tighten the bolts on the water pump holding tool into the threads on the water pump sprocket.
    2. Install the access cover bolts that were removed earlier to secure the water pump holding tool to the front cover assembly.
    3. Remove the 3 inner water pump sprocket to water pump blots.

I suspect the water pump needs replacement, since there is liquid like fluid below engine. what are the steps one must take, to replace the water pump. Why is it not simple to do? Looks like alot of...


1.3L & 1.6L Engines
  1. Remove the timing belt cover, timing belt, tensioner, plate and spring.
  2. Remove the water pump mounting bolts.
  3. Remove the one (1.6L MFI engines) or two (1.3L and 1.6L TFI engines) small rubber seals from between the water pump and the oil pump, and the water pump and the cylinder head.
  4. If necessary for clearance, remove the oil level dipstick tube retaining bolt from the engine block and the alternator adjusting brace.

WARNING

Do NOT use a prybar between the water pump housing and the engine block to separate the two components; this can cause scratches and/or gouges, which can prevent proper sealing.


  1. Pull the water pump off of the engine block. If the water pump is difficult to remove from the engine block, use a soft-faced mallet to tap the water pump housing until it loosens.

Do not disassemble the water pump; if the water pump is damaged or defective, the entire unit is replaced.

  1. Thoroughly clean the water pump gasket mating surfaces of old gasket material and corrosion.
90883pg0.jpg

The drive belt can be used to hold the fan stable while loosening the mounting fasteners
90883pg2.jpg

Loosen the fan bolts, then either remove the drive belt before the fan and shroud ...
90883pg4.jpg

... or wait to remove the belt, along with the water pump pulley
90883pg5.jpg

Once the cooling fan and shroud are removed, access can be gained to many of the engine components, including the water pump

To install:

  1. Along with a new gasket, install the water pump on the engine block. Tighten the water pump mounting bolts to 88-115 inch lbs. (10-13 Nm).
  2. On 1.3L and TFI 1.6L engines, install two new rubber seals: one between the water pump and oil pump, and the other between the water pump and the cylinder head. The MFI 1.6L engines only use one rubber seal, located between the water and oil pumps.
90883g43.gif

Be sure to install the two rubber seals between the water pump, oil pump and cylinder head before installing the timing belt cover-1.3L and 1.6L TFI engines
90883g42.gif

The 1.6L MFI engine uses only one rubber seal between the oil pump and water pump

  1. If removed, install the alternator adjusting brace and the oil level dipstick retaining

How to replace water pump of 1976 ford e-250


Hello, follow this steps to replace the water pump:

1. Disconnect the negative battery cable,using a screwdriver to unscrew the clamp that secures the cable to the negative (-) post. Pull the cable away from the battery post.
2. Use a jack to elevate the Ford Taurus and use jack stands to shore up the jack. Alternately, you can use tire ramps.

3. Discharge the pressure in the radiator by unscrewing the cap. Remove the drain plug located underneath the radiator. Catch the coolant in a resealable container. Clean up any spills.

4. Disconnect or remove the parts in front of the water pump, using an adjustable wrench. In order, this includes the right inner splash shield, lower heater hose, upper and lower tube bolts from radiator, air cleaner assembly, battery and battery tray, water pump belt, upper radiator hose, engine vent hose, trans axle 10-pin connector, radiator bypass hose and thermostat housing.

5. Remove the water pump mounting nuts and connector hose. Unbolt the water pump from the mount. Clean off the mounting area with a shop rag.

INSTALLING THE NEW WATER PUMP:

1. Inspect the new water pump to ensure it's identical to the old pump and free of any metal splinters or debris.

2. Arrange the new gasket onto the water pump. Place a bead of high temperature automotive sealant around the area where you removed the old pump and hold the gasket in place on the new water pump as you mount the entire assembly on top of the sealant.

3. Place the new nuts into the holes in the Ford Taurus' water pump in any order for the S-type engine and in a cross configuration on the U-type engine. Using a torque wrench while the sealant is still wet to obtain a better hold, tighten to 15 foot pounds of torque.

4. Reassemble the other engine parts in the order they came off the Ford using an adjustable wrench. Replace worn parts with new ones, as needed.

5. Replace the drain plug and refill the radiator with the amount and type of coolant specified in your owner's manual. Remove the jack stands and release the jack or drive the ford off the tire ramps.

6. Attach the negative battery cable to the post and tighten the screw on the clamp. Start the engine and check for leaks. Then, close the hood

2004 chrysler 300m 3.5L waterpump location and does it run off the timing belt/chain


Yes the water pump does run of the timing belt system.
Directly from the service manual:

The 3.5L water pump has a die cast aluminum
housing and a plastic swept vane impeller. It bolts
directly to the right rear timing belt cover using an
O-ring for sealing. The water pump is
driven by the engine timing belt.

REMOVAL
The water pump on all models can be replaced
without discharging the air conditioning system.
WARNING: DO NOT REMOVE PRESSURE CAP
WITH THE SYSTEM HOT AND UNDER PRESSURE
BECAUSE SERIOUS BURNS FROM COOLANT CAN
OCCUR.

NOTE: It is normal for the water pump to weep a
small amount of coolant from the weep hole (black
stain on water pump body). Do not replace the
water pump if this condition exists. Replace the
water pump if a heavy deposit or a steady flow of
engine coolant is evident on water pump body from
the weep hole (shaft seal failure). Be sure to perform
a thorough analysis before replacing water
pump.

(1) Drain cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).

(2) Remove accessory drive belts (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
REMOVAL).

NOTE: The water pump is driven by the timing belt.

(3) Remove engine timing belt (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT AND
SPROCKETS - REMOVAL).

(4) Remove water pump mounting bolts (Fig. 31).
Note position of longer bolt for proper re-installation.

(5) Remove water pump body from engine

I need to replace the fuel filter on my 2003 GMC Sierra 2500 HD Duramax Diesel 6.6L. Please tell me how to do it.


ITS A SPIN ON FILTER, YOU NEED TO DISCONNECT THE WATER SENSOR ON THE BOTTOM OF THE FILTER, THEN USING A STRAP FILTER WRENCH LOOSEN THE FILTER AND SPIN IT OFF.

CHECK THE FILTER HOUSING TO BE SURE THE INNER FILTER SEAL ISN'T ON THE HOUSING AND CAME OFF WITH THE FILTER.

REMOVE THE WATER LEVEL SENSOR AND DISCARD THE SEAL.

INSTALL THE WATER LEVEL SENSOR ON THE NEW FILTER. USING A LITTLE GREASE ON THE INNER FILTER SEAL AND ON THE OUTER O-RING TO HOLD IT IN PLACE, SPIN ON THE NEW FILTER.

OPEN THE VENT ON THE UPPER SIDE OF THE FILTER HOUSING. PUSH DOWN ON THE HAND PUMP QUICKLY UNTIL THE FUEL IS COMING OUT OF THE VENT. CLOSE THE VENT AND PUMP THE FILTER PUMP UNTIL IT FEELS SOLID. AT THIS POINT START THE ENGINE. IF IT STALLS PUMP IT UP AGAIN AND RESTART THE ENGINE. IF YOU HAVE AN ASSISTANT THEY CAN PUMP THE FILTER PUMP WHILE THE ENGINE IS RUNNING AND QUIT WHEN YOU FEEL THE ENGINE IS NOT GOING TO STALL. ABOUT 10 TO 15 SECONDS USUALLY WORKS.

CHECK FOR LEAKS.

BEFORE STARTING THE ENGINE USE BRAKE WASH TO REMOVE THE FUEL SPILLED DURING THE FILTER REPLACEMENT. ALLOW IT TO DRY BEFORE STARTING THE ENGINE.

RATE ME PLEASE.

98 pathfinder water pump


Chances are if you have a coolant leak right under the water pump, especially with engine running, the inner seal in the water pump is shot & the entire water pump will need to be replaced with a reman / new one. For the amount of hassle required to replace the seal it is worth the couple hundred bucks for the new pump.

There would definitely be overheating problems if the pump were not working at all. You will also have overheating problems present if there is low coolant, make sure the rad is topped up, with heater(s) on "Hot" inside & run the engine until it shows warm on the gauge. Make sure all of the belts are tight & pump looks like its spinning.
