What year is it?
if it's an E36 it should have a viscous coupling.
you need a very large spanner or large cresent, [cant remember size] put the pulley & belt back on & tighten. the put the spanner or cresent on the large nut behind the viscous coupling & with a hammer give the spanner a quick hard wack clockwise to loosen. usually one or two decent hits free it enough to undo by hand. then put back together opposite directions. hope this helps.

Need direction too remove water pump on 5.2


1. Remove the serpentine belt, use a socket wrench on the tension pulley to release the belt. 2. Remove the air conditioning unit, sorry EPA, and remove the fan assembly. There are at least eight long screws to remove, make a note of where you pulled each screw, for reinstallation. 3. Remove the thermostat, it is under the large hose on the top of the engine. 4. Remove the water pump assembly and short hose, slowly. 5. To reinstall, get Indian head lubricant sealer for the gasket installation. 6. Install the water pump with screws and hoses, let the gasket sealant cure for two hours before installing the fan and air conditioner unit. 7. After two hours, reinstall all units and fill with antifreeze. Let the car sit for an hour to check for leaks. After an hour with no leaks, start engine and check for leaks. After all leaks have been fixed, check thermostat gauage and top return hose for heat. 8. your done.

Replacing a thermostat on 2004 nissan sentra


  • Prepare for the replacement by disconnecting the negative battery cable and draining the engine coolant into a container--you need to remove the drain plug from the radiator first and then the drain plug at the engine block.


  • Remove the engine's cooling fan by loosening the fan/water pump pulley nuts, unclipping and removing the fan shroud's lower half, removing the water pump pulley nuts and pulling the fan out from underneath.

    Disconnect all components blocking access to the thermostat by removing their bolts. On four-cylinder engines, this includes the air cleaner, air intake duct and the power steering pump's support bracket. On a 3.3 liter V6 or SOHC engine, remove the upper radiator hose from the intake manifold's coolant outlet.

  • Slip off the drive belts blocking the thermostat by turning their tensioner bolts with a wrench or breaker bar. On a 3.3 liter truck or DOHC engine, follow this by removing the upper idler pulley bracket. On a 3.5 liter engine, remove the water pump drain plug from the front end of the block.

  • Detach all hoses from the thermostat housing cover by loosening the hose clamps with pliers; this usually includes the lower radiator hose. This is only needed on V6 engines; you will keep the hose attached on a four-cylinder.

  • Remove the thermostat housing cover by removing its bolts. There will be some coolant spilling out when the gasket seal breaks.


  • Disconnect and remove the thermostat from its cover by removing its screws. Take note of how the thermostat is positioned within the cover.

  • Scrape away all traces of gasket or sealant from the housing and cover and clean the surfaces with lacquer thinner.

  • Apply RTV sealant around the edge of the thermostat cover. You need to re-install the cover within five minutes of applying this sealant.

  • Mount the new thermostat into the cover in the same position the old thermostat was in.

  • Re-install the thermostat cover and all other parts in reverse order of installation.

  • Wait a half hour for the RTV sealant to cure before refilling the engine coolant. Use fresh coolant if the old coolant is contaminated.

    Removing water pump what does it involve


    Hi, the upper fan shroud needs to be removed, 7 -10mm bolts, then the fan blade needs to come off, screwed to the water pump, would have to get a tool to hold the pulley, then loosen the big fan nut with a wrench, then the belt comes off, drain coolant, take off the hoses from the pump, then remove the 4 mounting bolts. tap the pump with a hammer( to break the seal, as it will be stuck to the engine), clean all old gasket debris from both sides of the engine, glue the new gaskets to the pump, reinstall the new pump with 4 bolts, and tighten, reassemble completely, fill coolant, run the engine with the cap off(to bleed the system), untill the thermostat opens. Topp off the coolant, and road test. Good luck...

    How to replace a water pump on mercedes e320 1997


    It is not complicated, depending on what hands-on level of DIY on car. Here are what need to do, so you can estimate how easy or hard when you look through your engine. Drain all the coolant, remove the thermostat housing, remove the fan, belt. Remove the water pump pulley. There are 4 bolts to hold the water pump in place.If you think you can take them out and put them in without removing the AC compressor then you can do it. I did it twice without removing the AC. The pump was fine for the second time, but for leaking seal. At dealer, it is easier to access from the bottom since they have a lifter. But it is doable at home. Have fun if you decide to do it.

    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.
