Water pump tube


The heater pipe slides out and the pipe is grooved for an o-ring that seals it from leaks. The pipe may be corroded in place and hard to twist and slide out. Try soaking it in wd-40 or similar product for at least an hour, then with a good set of pliers, grasp the pipe and try to twist it free while pulling outward, once removed, clean all the corrosion off the pipe and groove, preferabley with a power wire wheel. Slightly lube o-ring and fit it to the groove on the pipe and insert it into the new water pump being careful not to split the new ring.

How to change water pump in 1987 chevy nova


1. Remove mounting bolts and remove upper timing cover and gasket. Drain coolant into clean bucket.
2. Loosen the 4 water pump pulley mounting bolts. Loosen alternator adjusting and mounting bolts and remove the belt.
3. Remove the water pump pulley bolts and the pulley.
4. Remove the water pump inlet mounting bolt from the side of the block and then remove the 2 nuts attaching the pipe to the water pump. Remove the pipe.
5. Remove the mounting bracket bolt and then remove the dipstick tube. Plug the hole with a rag. Remove the right hand under cover and the power steering adjusting bracket ( if it has power steering).
6.Remove the 3 bolts and remove the water pump. Keep coolant OFF the timing belt (plenty of rags to soak it up)., Remove the O ring from the block.
7. To install a new pump, start by replacing the O ring in the block. Then the reverse of these steps.
8. Water pump mounting bolts are torqued to 11 ft.lbs only. Also replace the O ring on the dipstick tube and coat it with oil before reinstalling.
9. Refill the cooling system and run the engine up to operating temperature, with the heater running. This will force the air out of the system. Once the air is out top up the rad and replace the rad cap.

Need to replace water pump on a 2000 Dodge Durango. Would like any details on how to to it.


3.9L, 4.7L, 5.2L, 5.9L, 8.0L Gasoline Engines
  1. Carry out the "Common Steps" above.
  2. Remove the upper radiator hose.
  3. Remove the fan and shroud assembly.
  4. On engines except 4.7L, remove the four water pump pulley bolts and remove the pulley.
  5. Remove the heater hose pipe mounting bolt, if fitted.
  6. On engines except 4.7L, loosen the bypass hose clamp at the water pump.
  7. Remove the seven water pump mounting bolts and, on the 4.7L, one nut.
WARNING Bolts may be of different lengths. Be sure to note their locations.
To install:
  1. Reverse the removal procedure.
  2. The 8.0L engine uses an O-ring to seal. Use a new one and lubricate it with petroleum jelly before installation of the pump. Also, use sealant on the threads of the heater hose pipe, position the pipe as shown before installing the pump and tighten the nut to 12 ft. lbs. (16 Nm).
  3. On pushrod engines, connect the bypass hose to the pump while installing it.
  4. Tighten the bolts to 30 ft. lbs. (40 Nm) on pushrod engines, 40 ft. lbs. (54 Nm) on the 4.7L engine.
  5. Spin pump to ensure the impeller is not rubbing against the timing chain case.
  6. When installing the heater hose pipe, ensure that the slot in the pipe bracket is bearing against the mounting bolt. This will hold the pipe in as far as possible to prevent leaks.
  7. Tighten pulley bolts to 20 ft. lbs. (27 Nm) on V-6 and V-8, 16 ft. lbs. (22 Nm) on the V-10.

How to replace the water pump


Water Pump
REMOVAL & INSTALLATION
CAUTION
Never open, service or drain the radiator or
cooling system when hot; serious burns can occur from the steam and hot coolant.
Also, when draining engine coolant, keep in mind that cats and dogs are
attracted to ethylene glycol antifreeze and could drink any that is left in an
uncovered container or in puddles on the ground. This will prove fatal in
sufficient quantities. Always drain coolant into a sealable container. Coolant
should be reused unless it is contaminated or is several years old.

2S-ELC Engines

  1. Drain the cooling system.
  2. Remove the timing belt as described in this section.
  3. Remove the alternator adjusting bar.
  4. Disconnect the lower radiator hose from the water inlet housing.

    89553g42.gif



  5. Disconnect the water temperature switch from the water inlet housing.
  6. Disconnect the water by-pass hose from the water pump.
  7. Remove the two heater pipe clamp bolt. Remove the two nuts and heater pipe

1997 Dakota v8 water pump replacement steps


Hope this helps!

Common Steps
  1. Disconnect the battery negative cable(s).
  2. Drain the cooling system.
  3. Remove the accessory drive belt.
  4. Remove the lower radiator hose (except Diesel).
  5. Disconnect the heater hose from the pump, if fitted.

WARNING Most cooling system hoses use "constant tension" hose clamps. When removing or installing, use a tool designed for servicing this type of clamp. The clamps are stamped with a letter or number on the tongue. If replacement is necessary, use only an OEM clamp with a matching ID.

Heater hose pipe O-ring (arrow): twist gently when removing or installing; check condition; lubricate with coolant before installing

CAUTION Always wear safety glasses when servicing contact tension clamps.


  1. Always use a new gasket when installing the water pump. Clean mating surfaces thoroughly before installation.
  2. This would be a good time to replace radiator hoses. At least, inspect them carefully for aging or other damage.
  3. If the heater hose pipe was removed, use thread sealant or equivalent on the pipe threads (if threaded), or lubricate any O-rings with coolant before installing.
  4. Check the accessory belt routing against the plate in the engine compartment before starting engine.
  5. Allow the engine to reach operating temperature and check for leaks.

How do i change the water pump on a 1999 2.5 v6 chrysler sebring?


Hello,

Removal:
Drain cooling system, remove the timing belt if necessary. Remove water pump mounting bolts. Separate water pump from water inlet pipe and remove.

Inspection:
Replace water pump if it has damage or cracks to pump body. Check the shaft seal for any leaks as evidence by traces of coolant from vent hole. Check for any impeller rubbing inside pump, and for loose or rough bearings.

Installation:
Clean all gasket and "O" ring surfaces. Install NEW "O" ring on water pipe (wet "O" ring with water to aid assembly). DO NOT allow oil or grease to contact "O" ring. Install NEW gasket on water pump, and install pump inlet opening over water pipe. Install pump-to-block bolts and tighten to specification 18 FT. Lbs. (25n.m). To complete installation, reverse removal procedure.

Hope this helps :)
