SOURCE: how to change a engine drain plug on a 1995 jeep

on metal tank units just unscrew it. I generally replace them with an npt brass plumbing plug. drains often fail... the plug lasts forever. On plastic tanks some are molded in, if so cut it off with a hacksaw blade, thread it to npt plug thread and use plug. Wrap either with teflon tape before installing.
A faster way of draining is to remove lower hose at the radiator.
Never open the system when it's hot. National pipe thread plugs are tapered. Don't overtighten or they will split what they are being installed in.

How to replace the heater hose assembly on a 2000 grand voyager?


not to make light of your request but just undo fastening clamps for the hoses at both ends and remove one hose at a time to replace.as they need to be installed in the same position for correct flow.you may need to cut the hose were they are connected to the spigot nipple but just the hose not the nipple,to get them to pull off.

How to change radiator


Radiator REMOVAL & INSTALLATION Cirrus, Sebring Convertible, Stratus and Breeze CAUTION
Do not open the radiator draincock or remove the radiator cap when the cooling system is hot and under pressure. This can cause serious burns from hot, pressurized coolant. Allow a sufficient amount of time for the cooling system to cool down before opening up the system. NOTE: The radiator uses plastic tanks. Plastic tanks, while stronger than brass, are subject to damage by impact, such as slipped wrenches. Use care when working around these radiators.
  1. Disconnect the negative battery cable from the left strut tower. The ground cable is equipped with an insulator grommet, which should be placed on the stud to prevent the negative battery cable from accidentally grounding.
  2. Remove the air inlet resonator.
  3. Place a large drain pan under the radiator drain plug. Drain and properly contain engine coolant. NOTE: To open the drain plug on models equipped with a 2.5L engine, use a 3⁄8 inch drive extension 3 inches (7.6cm) long and a 19mm socket with universal joint. The drain plug can also be accessed by removing the right front fog light in the front lower bumper fascia.
  4. Remove the upper radiator crossmember as follows:
    1. Remove the push-in mounting fasteners securing the front fascia/grille unit to the radiator support crossmember.
    2. Remove the mounting bolts securing the support braces to the bottom of the crossmember.
    3. Remove the bolts securing the crossmember to the radiator closure panel.
    4. Remove the mounting nuts attaching the hood latch to the radiator crossmember. Remove the crossmember from the vehicle. Fig. 2: Using a small flat bladed tool, pry up the center portion of the plastic front grille/fascia retainers, then pull them out 90903p02.jpg
      Fig. 3: To aid in a straight reassembly, matchmark the washer screws to the radiator crossmember using a marker 90903p03.jpg
      Fig. 4: Remove the radiator crossmember mounting fasteners 90903p04.jpg
      Fig. 5: Remove the mounting bolts for the hood lock latch mechanism 90903p01.jpg
      Fig. 6: Remove the radiator support crossmember 90903p08.jpg
      NOTE: The following step and associated photos describe original type hose clamps. Some vehicles may instead have a worm gear type clamp, which can be loosened with a screwdriver.

  5. Using pliers, compress the tabs on each hose clamp, then slide the clamp a few inches away from the hose end. Carefully twist and pull the hoses from the radiator.
  6. Disconnect the engine block heater wire, if equipped.
  7. Disconnect and plug the transaxle cooler lines, if equipped.
  8. Remove screw attaching support bracket for external transaxle cooler lines to the left side of the radiator, if equipped. Fig. 7: Relieve the tension from the hose clamp, then disconnect the upper coolant hose at the radiator 90903p09.jpg
    Fig. 8: If equipped with an automatic transaxle, loosen the hose clamp and disconnect the transmission fluid cooler hose 90903p14.jpg

    Fig. 10: Disengaging the cooling fan electrical connector 90903p18.jpg

  9. Remove the screw attaching the support bracket for air conditioning lines from the right side of the radiator. Remove the support bracket.
  10. Unplug the cooling fan wiring.
  11. Remove the air conditioning condenser mounting screws. Use care when working around the air conditioning condenser. Avoid bending the condenser inlet tube. Care should be taken not to damage the radiator or condenser cooling fins or water tubes during removal. It is not necessary to discharge the air conditioning system to remove the radiator. Fig. 11: Access to the lower radiator cooling hose (1) and lower left side A/C condenser-to-radiator mounting fasteners (2) is possible after removal of the left fog light 90903p12.jpg
    Fig. 12: Access to the lower transmission fluid cooler line (1) and lower right side A/C condenser-to-radiator mounting fasteners (2) is possible after removal of the right fog light 90903p13.jpg

    Fig. 14: Unclip the A/C line from the cooling fan module 90903p15.jpg
    Fig. 15: Remove the radiator assembly from the vehicle 90903p07.jpg

  12. Carefully remove the radiator from the vehicle. The cooling fan/shroud assembly can be separated from the radiator at this time. To install:
  13. If separated, install the cooling fan/shroud assembly to the radiator unit.
  14. Lower the radiator and fan module (assembly) into position. Seat the radiator assembly lower isolators in the mount holes provided.
  15. Install the air conditioning condenser mounting screws and tighten to 45 inch lbs. (5 Nm).
  16. Connect the radiator hoses and tighten the hose clamps to 22 inch lbs. (2.5 Nm). Be sure the hoses do not interfere with the accessory drive belt, and be sure the upper hose clamp does not interfere with the hood liner.
  17. Connect the cooling fan wiring.
  18. Connect the transaxle cooler lines to the radiator, if equipped.
  19. Install the upper radiator crossmember as follows:
    1. Place the radiator crossmember into the vehicle in proper position.
    2. Install the hood latch to the radiator crossmember. Install and tighten the hood latch mounting nuts.
    3. Install and tighten the crossmember-to-radiator closure panel mounting bolts.
    4. Install and tighten the mounting bolts that secure the support braces to bottom of the radiator crossmember.
    5. Install the push-in mounting fasteners holding the front fascia/grille unit to the radiator crossmember.
  20. Connect the engine block heater, if equipped.
  21. Install the air inlet resonator.
  22. Fill the cooling system with the correct type and amount of engine coolant.
  23. Reconnect the negative battery cable. Start the engine and allow it to idle until it reaches full operating temperature. Check the cooling system for correct fluid level and top off if necessary.

  1. Drain the engine coolant into a suitable container.
  2. Open the instrument panel glove compartment. Push in on the sides of the compartment to release it, allowing access to the heater core.
The heater core can be damaged if too much force is applied to the heater core pipes during hose removal.
  1. Remove the heater module screws and remove the heater module assembly cover. For vehicles equipped with A/C, remove the air conditioning evaporator temperature sensor assembly from the heater and A/C cover.
  2. Remove the heater core screw and clamp.
  3. Remove the hose pipe clamp screw and the hose pipe clamp. Clamp off the heater hoses.

  2. Remove the heater core by carefully pulling it towards you.
0900c152800b8724.jpgFig. 4: Exploded view of the heater core removed from the heater module assemblyTo install:
  1. Install the heater core and attach the heater hose assembly to the heater hose pipes. Note the following:
    1. Lubricate the heater core pipes with petroleum jelly for ease of installation and to assure a good seal.
    2. Be sure the seals around the heater pipes remain in place when installing.
    3. To verify that the seal is installed correctly, observe the seal from inside the engine compartment. If the seal has leaks, apply a sealer between the heater core pipes and the evaporator housing.
  2. Install the hose pipe clamp and the bolt/screw. Unclamp the heater hoses. Tighten the hose pipe clamp bolt/screw to 16 inch lbs. (1.8 Nm).
  3. Install the heater core clamp and screw. Tighten the screw to 16 inch lbs. (1.8 Nm).
  4. Install the heater module assembly cover and secure with the retaining screws. Tighten the screws to 18 inch lbs. (2 Nm).
