hey guys, im due for my 100k and im planning to change my water pump too while im at it to a N1 item. what id like to know is do i need to change all the other parts associated with the water pump like thermo stat, radiator hose...ect. reason i ask is that i got quoted 700 for aftermarket water pump, nizmo thermo stat, radiatior hose, ect....im thinkin its abit overkill, but hey maybe it isnt.
also my engine occasionally makes a loud squeeling sound on start up which i think could be a bearing?? wats the going cost for replacing idler and tension bearings??
cheers.
