Hi,

Sounds like the bearing on my 24v 1995 164 3.0 water pump is not a happy bunny as the revs go above 2,000rpm so going to change it.

Know it's a cambelt change too but that's also pretty much due anyway.

Question is, can the water pump be changed without having to remove any of the cam pulleys? Any little bolts that have a tendency to break and need drilling out?

Thanks.

Loosen bolts on water pump pulley before you remove serpentine belt? Put rig pin in serpentine belt tensioner, too. Once serpentine belt off spin water pump shaft and check for noise and play in the bearing. You will have to take off serpentine belt pulleys to get water pump off.

You don't have to remove cam pulleys to remove water pump. but put engine at top dead center (TDC) and lock pulleys together and pin timing belt tensioner before you take timing belt off.

It is a crap shoot on whether one or more M6 bolts holding pump on with come not come out easily. You can shock them with a frap on the head of the bolt with a hammer and a drift pin if you like.

Many thanks, Steve.

M6 bolts? Could Alfa have made them any smaller? Shocking them with a hammer first sounds a good idea.
Took serpentine belt off today and actually the water pump feels OK. It is the power steering pump that feels rough. Also noticed the pivot that holds the tensioner has a lot of play - possibly not helped by the excess axial play in the power steering pump. No idea where to get hold of one of those. Might have to bore it out and use a sleeve.

Going to replace the power steering pump this weekend. Have about 1.5 litres of Dexron II ATF fluid. Likely to be enough?

All the best :)
