[DML] Re: Water pump squeaking. How long have I got?

["Mike Bosworth" <mike.bosworth@xxxxxxxxxxxxxx>]

I agree with David .. Its not just a 'replacing water pump job' its 
all of those things listed in the 'oh and while im in there' category 
Another job is all of the cleaning you end up doing in the 'Valley of 
Death' it can get really grubby in there, especially in the 2 deep 
wells in there, When everythings removed it can look kind of scary 
but nothing that is beyond you. 

Buy a decent small 1/4" drive set with knuckle joint for the manifold 
bolts and soak them in penetrating fluid for a couple of days before, 
give the heads of the same a sharp tap with a hammer before you try 
and get these pesky blighters out :)

Write a list up of all the o rings and washers etc you want to 
replace, if you need a list i have one of all the bits i got. Nothing 
worse than starting a job and not having the bits ready.

Replace all of the pump, y pipe and intake manifold bolts with new 
ones copper grease them on replacing them...and buy a 7mm x 1 thread 
tapper to clean up the threads before. 

Good idea to get hold of a 7mm helicoil / drill kit before you start. 
I would say one  manifold bolt and one of the 'long' y pipe bolts 
will give up on you based on my talking to others.

Its a good long weekend job, get a friend to help out if you can 
makes the job more fun and with the bending over the facia count on 
an ackey back :) Take lots of photos and lable things up as you go, i 
used a Dymo and carefully tagged the bits ( Most of them are still 
attached 6 months on ...handy references)

Check out Jordan site for references / pics, best online help i have 
ever come across on there....
