I have a 1999 vw passat and i need to remove the radiator in order to change the fan. how do i remove the radiator?


Well, there is a catch 22 to your plan. In order to remove the radiator you have to remove the fan first. Check around the housing for the fan, you should find plastic pressure clips that hold the fan in place. Release the clips and you should be able to lift the fan housing and shroud out or drop it through to the bottom of the vehicle. To remove the radiator you have to remove the fan shroud and fan in order to locate and remove the retaining bolts for the radiator. There are usually 2 on the bottom of the Radiator sometimes accessible from the bottom of the vehicle and 2 near the top of the radiator, usually covered by the fan shroud.

Remove the battery tray using the following procedure:
Remove the four battery tray bolts.
Remove the battery tray from the vehicle.
Remove the serpentine drive belt.
Remove the cooling fan assembly using the following procedure:
Remove the wishbone-shaped engine mount strut by removing the bolts and nuts at the engine mount bracket and on the upper radiator support.
Remove the strut from the vehicle.
Disconnect the cooling fan harness from the engine wiring harness.
Reposition the wiring harness at the upper radiator support.
Remove the cooling fan shroud bolts.
Remove the right side radiator bracket.
Remove the cooling fan shroud with the electric cooling fan motors and fans as an assembly.
Remove the thermostat housing and the radiator hose using the following procedure.
Partially drain the engine coolant.
Use hose clamp pliers to remove the radiator hose clamp to the water inlet housing and disconnect the radiator hose.
Use hose clamp pliers to remove the heater hose clamp to the water inlet housing and disconnect the heater hose from the water inlet housing.
Use hose clamp pliers to remove the surge tank inlet hose clamp from the water inlet housing and disconnect the surge tank hose from the water inlet housing.
Remove the water inlet housing bolts and remove the water inlet housing.
Remove the outboard generator bolt and loosen the inboard bolt.
Remove the idler pulley bolt and idler pulley.
Unplug the electrical connector from the alternator.
Pull back the protective boot from the alternator "BAT" terminal, remove the nut and disconnect the heavy "BAT" wire from the alternator terminal stud.
Remove the alternator from the vehicle.
To Install:
Position the alternator to the engine.
Plug in the electrical connectors and install the heavy "BAT" wire to the alternator terminal stud. Tighten the nut to 15 ft. lbs. (20 Nm). Press the protective boot back in place over the stud terminal and nut assembly.
Install the outboard alternator bolt into the alternator housing.

Install the idler pulley and idler pulley bolt.
Tighten the bolts in the following torque sequence:
Tighten the idler pulley bolt to 37 ft lbs. (50 Nm).
Tighten the alternator bolts to 37 ft. lbs. (50 Nm).
Install the water inlet and thermostat housing and the radiator hose, observing the following:
Inspect and clean the mating surfaces on the thermostat cover and its mounting surface on the engine.
Use RTV Sealer GM #1052366 or equivalent on the mounting bolts since the threaded openings are open to the cooling system and the torque requirement is low.
Install the water inlet and thermostat housing and tighten the bolts to 80 inch lbs. (9 Nm).
Connect the surge tank inlet hose to the water inlet housing.
Connect the heater hose to the water inlet housing.
Connect the radiator hose to the water inlet housing.
Install the cooling fan assembly and tighten the radiator bracket bolts to 80 inch lbs. (9 Nm). Plug in the wiring harness at the upper radiator support. Plug in the cooling fan wiring harness to the engine wiring harness.

HOW DO I CHANGE THE WATER PUMP ON A 99 JEEP GRAND CHEROKEE ?


At least you have the 4 liter 6. Once you get all the **** out of the way its like replacing a W/P on an "old school" engine, very much like a Ford or Chevy straight 6. 1) Remove radiator top retainer (the metal U that looks like its the top of the radiator (#13 or 14mm sockets I think). 2) To completely get if off you also have to remove the grill (4-6 phillips screws), then 3) unbolt it from the tubular bumper retainers underneath the grill. 4) DO NOT remove the latch cable - no need. 5) Remove the top bolts holding down the fan shroud. Lift the shroud off its bottom "tabs" and push over the fan. 6) Using #10mm socket remove fan from fan clutch, then remove bolts holding fan clutch onto water pump pulley. 7) Pull out shroud, then fan, then fan clutch. Be very patient, lots of wiggling may be needed. 8) Locate belt tensioner on idler puller below the Power steering pump. Losen very little the pulleys center bolt (10mm), then use a 10mm w/entension to losen the pulley's tension (use counter clockwise/normal rotation to losen). 9) Draw a diagram of the belt routing - you will Never remember it correctly otherwise. 10) Tap the w/p pully and pull if off - do not hit radiator fins! 11) Drain the radiator (clockwise/right rotation opens petoc from factory radiators - counterclock used on aftermaket rads). 12) Remove lower raditor hose at radiator, then at pump (it will be a challenge). 13) Remove upper radiator hose from rad and from thermostat housing. 14) losen the Rubber heater hose from the metal hose screwed into the W/P. 15) Remove 4 bolts from W/P (13 or 14mm I think). The one at the 4oclock position is longer than the others. One is hidden at 6oclock.
16) Remove 2 bolts (14-15mm??) on bottom of Power Steering mount - these go through the W/P case to the block. You may also need to losen the top PS bolts so the PS Bracket can be loose at the W/P case. 17) Wiggle the W/P out from under the PS bracket. and pull off. (16b if needed, remove the upper idler pulley near the A/C unit.) 18) Remove the Thermostat (upper hose return) housing. Scrape off old gasket. Replace with 160deg or 190deg thermostat. Use silicone on gasket. 19) Carefully use a 17 or 19mm box wrench to remove the metal heater hose return line from the upper part of the old water pump. Coat threads with spark plug thread antiseize and screw onto new W/P. 20) Install new W/P gasket w/silcone, be careful to Not block the water holes. 21) Slide W/P under the P/S bracket and jiggle into place. Hand thread one of the top bolts to hold the W/P in place. 22) Insert the P/S bracket bolts and lightly tighten. 23) Jiggle W/P around and insert other bolts, start with the 6oc hidden bolt. Add remaining bolts and tighten to 25 or 250?ftlb (about 3/4 past socket-snug). 24) Tighten ALL P/S bolts. 25) Adjust metal heater pipe. Reinstall rubber heater hose. 26) Reinstall W/P pulley and Fan clutch, and upper idler if it was removed. 27) Thread NEW Belt on pulleys. 28) Tighten tension on idler. Tighten idler axle bolt. 29) Install lower rad hose. 30) Slide shroud over pulleys. 31) Install fan on clutch. 32) Clip shroud retainer bolt mounts back on top of radiator. 33) Install shroud. 34) Connect upper hose. 35) Reinstall radiator retainer. 36) Bolt retainer to Tubular bumper mounts. 37) Reinstall grill. 38) Wonder where the extra bolts etc are supposed to go. 39) Cuss - pray -cuss - pray. 40 ) sip some beer. 41) carefully inspect everything to ensure its back to the way it looked before (several pictures from a digital camera taken during the disassembly will help). 42) Close the rad petok. 43) Add 1 gallons of antifreeze. 44) Start engine and add another gallon of A/F. 45) Turn heater controls to HOT inside (no need for fan). 46) Water guage should show 180 to 210F. 47) Add 1 gallon of water. 48) Install New 18PSI rad cap. 49) Turn off engine and add water or A/F to overflow tank. 50) 1 hour later open Cap to see if level has settled. Add Water as needed to fill rad.
