Question about 1998 BMW 5 Series
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.
