Tips on R53 Water Pump Replacement

for a mcs 06, i had to remove the alternator to free up the supercharger. also, the intake manifold would not come-off. the right side end of the intake mani hits the top of the supercharger and will not come off. i had to grind a little bit to remove it. I replaced the oil dipstick tube o-ring and so with the crank sensor o-ring while in there.

also replaced all cooling hoses. noticed that after market hoses are a little wider than the original so space was tight but it worked ok.

In my case, it was the water pump oring that was leaking. the water pump was good. I replaced the water pump anyways.
I think the oring connection to the flange is the weak point. it is a bad design in my view.

one important info missing in the write-up is torque specs. this is a very useful data and should be added to add more value.

one additional comment. putting the car in service mode is a must to have enough room to work in the engine bay
