Tip & How-To about 1998 Ford Taurus

Water pump

To remove water pump loosen serpentine belt with a 3/8 breaker bar and set out of the way remove the 4 nuts on the pump housing and the 3 bracket bolts along with the upper and lower radiator hoses the small heater hose. The lower nuts can be reached thru the wheel well. Remove the allen bolts that hold the pump in the housing clean gasket area and replace. You may need to double nut a couple of the housing studs and remove for room on the housing

STEP 1. and STEP 2. remove your engine cover STEP 3. disconnect battery (8mm socket) and i removed strut tower brace just to have more working space (four 13mm nuts, 2 on each side) STEP 4. Remove coolant reservoir (two 10mm nuts on top, also disconnect hose and cap it off if necessary) STEP 5. loosen and remove serpentine belt by loosening tensioner pulley (15mm deep socket) TEP 6. Remove your alternator and bracket (three 15mm bolts on alternator) the bracket is held on by a 15mm nut on one end and a 10mm bolt on the other end, disconnect harness and remove positive cable (10mm nut) STEP 7. Disconnect heater hoses, inlet and outlet, (using pump pliers to compress clamps) cap off if necessary and set aside STEP 8. remove the belt tensioner assembly (three 15mm bolts, one is hidden on the bottom left side) Also this is a good time to check your power steering fluid

do you have to remove the timing belt to replace the water pump on a 1999 mercury mystique gs 2.0L


  • 1 Open the hood and disconnect the negative cable terminal from the battery using a wrench. This is the cable connected to the post with the negative sign next to it.
  • 2 Place a large drain pan under the radiator, open the radiator drain valve and loosen the radiator cap. Allow all the coolant to drain from the radiator and then close the radiator valve. Remove the drain pan from under the vehicle and cover it if you plan to reuse it later.
  • 3 Unfasten the two bolts from the top engine cover, which shields the water pump pulley. Use a ratchet, short ratchet extension and socket. When removing the cover detach the crankcase ventilation tube from the edge of the cover by hand.
  • 4 Raise the front of your car with a floor jack, support it with two jack stands and chock the rear wheels with a couple of wooden blocks.
  • 5 Rotate the drive belt tensioner clockwise using a breaker bar with a 3/8-inch driver. Insert the breaker bar driver in the square hole of the belt tensioner. Hold the belt tensioner in the release position and lift the drive belt from the pulleys. Slowly release the belt tensioner to its original position.
  • 6 Loosen the clamps holding the two hoses to the water pump using a Phillips-head screwdriver and detach the hoses from the water pump.
  • 7 Unfasten the three bolts that hold the water pump and housing assembly to the engine using a ratchet, short ratchet extension and socket. Remove the water pump from the engine.
  • 8 Unfasten the water pump body from the water pump housing bolts using the ratchet and socket.
  • Installing the water pump. 9 Remove old gasket traces from the mating surface of the water pump housing using a plastic scraper. Install a new water pump gasket following the instructions of the new pump manufacturer.
  • 10P osition the new water pump in place over the housing and install the mounting bolts by hand. Tighten the bolts to 18 foot-pounds using a torque wrench and a socket.
  • 11 Place the water pump assembly in position on the engine of your Mercury Mystique and install the new bolts (part number W701544) by hand. Tighten the bolts to 13 foot-pounds using the torque wrench, short ratchet extension and socket.
  • 12 Rotate the three water pump assembly bolts clockwise an additional 95 degrees using the socket, short ratchet extension and a degree wheel.
  • 13 Attach the two hoses to the water pump and tighten the hose clamps with the Phillips-head screwdriver. Reinstall the drive belt using the breaker bar.
  • 14 Lower your Mercury Mystique off the jack stands.
  • 15 Replace the top engine cover with the ratchet, short ratchet extension and socket. Refill the radiator with coolant and tighten the radiator cap.
  • 16 Connect the battery cable to the negative battery post using the wrench. Start the engine, check for coolant leaks around the water pump and add more coolant to the radiator, if necessary.

how to remove belts from 1994 dodge caravan 2.5 liter


Drive Belts

INSPECTION

See Figures 1, 2, 3, 4 and 5
Check the condition and tension of all drive belts every 12,000 miles, or at least once a year. Loose drive belts can lead to poor engine cooling and diminished alternator, power steering pump, air conditioning compressor, or emission air pump output. A belt that is too tight places a strain on the bearings in the driven component.

Fig. Fig. 3: Deep cracks in this belt will cause flex, building up heat that will eventually lead to belt failure

Fig. Fig. 4: The cover of this belt is worn, exposing the critical reinforcing cords to excessive wear

Fig. Fig. 5: Installing too wide a belt can result in serious belt wear and/or breakage
Replace any drive belt that is glazed, worn, cracked, or stretched to the point where correct adjustment tension is impossible. If two belts are used to drive a component, always replace both belts when replacement is necessary. After installing a new belt, run the engine for ten minutes, shut OFF the engine and recheck the belt tension. Readjust if necessary.

Two popular methods of checking drive belt adjustment are; the Belt Tension Gauge Method and the Belt Deflection Method. The former requires a special gauge and the latter requires a straight edge and scale or just a good eye for measurement. The deflection method will be used in the following belt replacement instructions. A rule of thumb for checking belt tension by the deflection method is to determine the midpoint between two pulleys of the drive belt and press down at that point with moderate thumb pressure. The belt should deflect to the measurement indicated in the following installation procedures. Adjustment is necessary if the belt is either too loose or too tight.

WARNING A belt adjustment which is either too loose or too tight will eventually damage the accessory that belt is driving. A too loose adjustment allows free-play in the belt which could transfer a whipping motion or shock to the accessory drive pulley. Similarly, a belt which is too tight will preload the accessory bearings, leading to early failure.


REMOVAL & INSTALLATION

Raise the front of the vehicle, support on jackstands and remove the lower splash shield if access is hampered due to space limitations when changing drive belts.

how do you use the wrench set to remove the fan housing from the water pump on a 99 chevy saburban


first you need a 3/8 drive breaker bar, insert the breaker bar drive into recess on belt tensioner. Then rotate tensioner to tighten tension on the belt. When the belt is tight put the wrench on the fan nut and give the wrench a couple smacks with a hammer and the fan should come right off. Installation is the reverse of removal.
