Question about 2004 BMW Z4

1 Answer

I am trying to replace the water pump on an 04 BMW Z4. I have removed the 4 bolts for the plastic water pump pulley and it does not want to come off. it feels like it will break if i pry on it and i'm not sure if there is something i am missing. also, it looks like it will be a tight squeeze to get the water pump out once i have gotten to it. do i have to take off the front metal plate to get it out?

After you have removed the 4 nuts securing the pump to the motor, you will need to install 2 6mm bolts in the two holes on the pump and alternately tighten the bolts to push the pump away from the motor. After the pump is loose, I recommend removing the the nuts from the top of the motor mounts and slightly raising the motor until the pump clears.

SOURCE: how to adjust halogen headlights on bmw z4

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

Trying to replace waterpump on a 96 suzuki swift but cant get the bottom pully off to remove the timing cover to get at the waterpump off. we cannot get a good angle to crack the nut. the frame is in the...


  1. Remove air filter to give you more room to play
  2. Loosen alternator and alternator tensioner. Alternator tensioner bolts to water pump so that bolt will need to come out.
  3. With the alternator loose, the main drive belt should be loose and be able to be removed, do this.
  4. Loosen the tensioner bolt for the air conditioner, on the underside of the engine. Losen the nut on the air conditioner tension wheel. The tensioner wheel should now slide up and down freely, allowing removal of the air conditioner belt.
  5. Remove the 4 x 10mm bolts on the water pump pulley. Remove the water pump pulley.
  6. Remove the 4 x 10mm bolts on the camshaft pulley. This is the main pulley that all the belts connect to. There is a large 17mm bolt in the middle of this pulley that does not need to be removed. (Crankshaft Bolt).
  7. The camshaft pulley should slide off, however you will probably have no clearance (because of the crankshaft bolt) to remove the pulley. The pulley has to be removed.
  8. Place a jack under the sump, use a piece of wood to protect the sump. Jack the sump up 1/2 inch. Undo the two 14mm bolts in the engine mounts. When the two left hand engine mount bolts are out, lower the jack slowly until you can slide the camshaft pulley out.
  9. Remove the plastic timing belt cover.
  10. You should now see the timing belt, remove the timing belt tensioner pulley, being careful not to move the timing belt wheels.
  11. Undo the bolts holding the water pump.
  12. Water pump should come off, water will come out if you haven't drained it.
  13. Scrape off gasket.
  14. Install new water pump.
  15. Reassemble in reverse order.

What must be removed to replace the water pump on a 1998 bmw 528i?


Not much really. I did my son's on the road in 20 degree weather. Remove the fan nut 1.250" wrench...left handed thread with the special tool. Remove fan, and shroud at the same time. Remove belly pan so you can drain the radiator. 16mm socket and 1/2 socket wrench to move the idler pulley tensioner. You move it not remove it. You move it enough to release serpentine tension. Remove belt. and 4 bolts holding the water pump pulley. Now the water pump is exposed. remove the bolts or nuts holding it in. go get some 6mm x 30mm hex bolts and use them to pry out evenly the water pump. That's it. reassemble, don't forget the o-ring.

Pretty easy. Just drain antifreeze. Then loosen 4 bolts that holds fan to pulley. Remove plastic fan schroud and fan pulley. Loosen water pump bolts in criss cross pattern and remove water pump. Clean surface install new gasket and water pump install in reverse order. Tighten in staggerd order to keep from breaking and warping. Don't forget to change thermostat good time to replace. Part should be about 50 bucs at your local parts store.

Need diagram to replace water pump


1) Drain the radiator. 2) Loosen the 4 bolts on the water pump pulley. You will remove the pulley and install it on the new pump. Just loosen the bolts 1/4" turn with the belt still on, this will prevent the pulley from turning. 3) Remove serpentine belt. 4) Remove 4 bolts and the pulley and set aside. 5) Remove two power steering pump bolts (15mm). You must do this because one of the bolts for the water pump is behind the PS pulley, and you can�t remove it without moving the PS pump out of the way. The bolts on the PS pump are in the 12 o�clock and 6 o�clock position. There is a large access hole in the PS pump pulley. Just line it up, slip in a long socket and remove them. Let the PS pump rest on the oil filter housing. 6) Remove water pump. There are 4 large bolts (15mm) and 4 small bolts (3/8") on the water pump. After the bolts are all out, I placed a length of pipe on the water pump and gave it a couple taps with a hammer and it popped right off. 7) Remove old gasket. The tool of choice IMO is a razor blade like you�d use to remove a windshield inspection sticker. Be careful not to score the mating surface. Remove old gasket and dry off surface. 8) Seat the new gasket and water pump in place, install all the bolts. 9) Reinstall the PS pump and torque bolts. 10) Install pulley on water pump and torque. 11) Install serpentine belt. 12) Re-torque bolts on water pump pulley if needed

Replace water pump


REMOVAL: 1) Remove the plastic belt routing diagram (there is a bolt underneath if I remember correctly)(yep, 8mm). 2) Using a 3/8 breaker bar or a ratchet, insert into the belt tensioner and push toward the back of the engine enough to release tension on the belt with one hand, and with the other hand, remove the belt from the water pump pulley. Then remove the bar/ratchet from the tensioner. 3) Remove the 4 bolts holding the shiny pulley onto the water pump (11mm). 3a) Large catchpan underneath, there's more coolant in there than it looks like. 4) With a ratchet and possibly a short extension, carefully remove the 5 bolts that hold the water pump onto the block (8mm). 5) Pry the water pump away from the block and clean both surfaces so they are free of gasket material. INSTALL: 1) Line up the gasket and *carefully* fit the new water pump onto the block. The holes are very easy to line up wrong because they are almost, but not quite, equally spaced from each other, so be VERY careful you have all 5 holes lined up right. 2) Screw each bolt in a few tuns to make sure they all go in smoothly. If you get any resistance (it will feel like it's crossthreaded), you have the holes wrong, and you need to rotate the water pump so the holes are lined up right. I can't stress this enough. 3) Torque all the bolts down (I can't recall the exact in/lbs - sorry) in a star pattern. 4) Mount the pulley onto the water pump shaft, torque bolts down (an air ratchet helps greatly here as the shaft will try to spin when the bolts start getting tight). 5) Release the tension as explained in step 2 at the top, put the belt back on the water pump pulley & double check to make sure it's on all the other pulleys while you're at it. 6) Bolt the plastic bolt routing diagram back onto the head. 7) Refill the resevoir and bleed the system of air. That's it! It's an hour or so job if you've never done it before. Note, if you're not using a gasket, get some water pump gasket sealer and make a gasket around the entire diameter of the mounting surface of the water pump. Remember to make little circles around the bolt holes also.
