I noticed that the belt on the pulley was shaking as the engine was on. I turned the engine off and i could move the pulley side to side atleast half a mm.

How much would a new water pump cost me ? It might get rid of a strange sound i keep hearing too (as someone else mentioned)

EDITED:

Water pump pulleys are not worth replacing, you can have my spare for $10 if you want it.

if it moves at all the bearing are going and u can't replace them. just go to the wreckers and find one with no movment won't cost to much.

brand new water pump = $33

brand new water pump = $33

Is that it ? Damn thats pretty cheap. Will have to get one.

I must have got ripped as mine cost $85.

i'm serious... thats how much they are going for... if you cant find it cheaper than say $45ish then i might be able to send one across ($33, plus postage).
