Thank you, I took mine to the dealer for a inspection because Iím doing a trip to Florida next month, and I want it to change the water pump before the trip since I have 93,000 on the X5 but, the dealer recommend me not to change since the cooling system looks good, also the said the BMW stop using plastic water pumps on the year 2000 and I have a2006. I think I will wait at least to 120,000.

Wonderful DIY!

Thanks friend.
Question. In cahnging just the thermostat and not the pump do you still need to remove pully? Also, how did you manage to remove the fan without holding the cluch? Would knocking the 32 mm wrench alone do the job?

Cheers

I'm not sure what you mean by "pulley". If you're just doing the thermostat then you're definitely going to want to remove the fan and shroud to get room to work in there. If I were just doing the thermostat that's what I'd do. Actually first I'd prob turn the car on (not start it) and set the thermostat to the highest (90F?) but on the low fan setting. Then stick a garden hose in the top of the reservoir tank while the radiator drain plug is still in and the engine block drain plug is out. This will circulate fresh water through the heater core and block. Once you've got just water coming out of the block, put the plug back in and do the same with the radiator drain plug out. Once that's just water, let it all drain and fill up with fresh coolant and distilled water mix and bleed the system accordingly.

I followed this write up to do this repair last weekend. Thanks you very much. One small item - had to turn the pulley with the Allen wrench clockwise to move the pulley down and to the left to relieve tension on the belts. It was very hard to move that thing, but once I understood the hydraulic tensioner concept, it made more sense.

Anyways - great writeup, and worked like a charm.

Thanks!

No doubt - saved a BUNCH of money over having the dealer do it.

In a weird sort of way, it was actually kind of fun.

i will be tackling this one on Saturday. ordering parts today. thermostat only though. my temp needle barely stays just above the blue mark even after 40 minutes of city driving. it'll get to the noon position but only if it's above 85 degrees outside. heater is mostly worthless in 50 degree weather. i think my water pump is fine, so will just start with the thermostat.

is the engine block drain plug easy to get to?

tip for getting the fan back on:

get a piece of string or some ~ 22 gauge wire. 2 feet should do.

position the fan in the shroud and wiggle both into their preliminary positions.

then wrap the wire around the fan nut, in essence, hanging the fan by the nut.

once the shroud is completely in place, you can use the wire to move the fan up and down into position on the threaded rod.

now the magic part. holding the two ends of the wire in each hand, you can spin the fan by lifting your right hand and lowering your left with, like you would spin a diabolo.

this threaded the nut beautifully.

i figured this out a few min ago and it worked a TREAT. i was actually surprised. i am always trying crap like this which does NOT work, but occasionally, lightning DOES strike!

one other quick note. be careful wiht the fan. the blades are somewhat fragile. if you drop the fan, you very well may break a blade.
