Replacing water Pump - Any Easy way to do it?

so my water pump shaft has some play in it (1/4" when not running and it does have some wobble when running but not a lot, i believe this is due to the belt being properly tightened, my pwr steering belt is loose and was what prompted me to dig in to it) and i'm replacing it while I'm doing the belts

it looks pretty tight in there to get everything out. Do i need to pull the radiator and the front fascia? (which also means the ARB and the winch etc) or can i do it from above without pulling that stuff?

Any advice would be helpful - water pump is already on the way and i'm hoping to do it this weekend if everything works out with the parts arriving from AB.

No you don't need to pull the radiator. My only tip would be to take a piece of cardboard and, using the new gasket, trace out the shape of the water pump and holes. When you remove a bolt, put it in the corresponding hole in the cardboard. This will help with reassembly since all of the bolts are different lengths.

But some cardboard or thin ply between your work space and the rad ... In case your hand slips ... You don't want to hit the rad unnecessarily.

Buy the autozone one with lifetime warranty. And don't over tighten the bolts.

Yes, definitely do this. This is something I do on all cars when working on the front of the engine.

Buy genuine. Aftermarket are crap IME. I pull the rad because it is not that hard to do and gives more space. If I had oil cooler lines I would leave it in place with cardboard as noted above. Now is the time to do belts and hoses if they are at all suspect -- and a new fan clutch. Make sure you understand how to bleed it properly. Have new plastic plugs handy or replace with brass, those plastic bastards always seem to break or cross thread. Can clutch tool is very important, refit the fan clutch with antiseize on the threads to the snout.

Brian i would like to borrow the fan tool.. (i ordered one from AB as well... since its something i'll need)
parts bought so far amount to the following

waterpump (AB STC483)
Hose Kit radiator (AB)
thermostate
clamp kit for hoses (dunno if i'll need it but .. it was cheap @ $10)
belt kit
gasket sealant (hydromar)
fan tool

my fan clutch is fine but worthwhile to changeout?

i have rave as well (which is great)..

i'm going to try and do it without pulling the Rad.. (since that means oil cooler lines, ARB, Winch, and a host of other bits)

Id say take time the clean the RTV or whatever out of the threads in the block/front cover. IIRC it doesnt take much to seal it up. I am with Ron on this one, pony up for the genuine water pump.

Robert,

Why would you need to pull the bumper to pull the Radiator? It comes out easy peasy. I pulled my and got it tested and recored when I did my water pump.

The fan clutch is simple enough to replace I would and keep the current as a spare. But I have spares for everything.

frankly i've haven't done it before so ignorance on my part wrt pull the bumper. I may pull the radiator and leave the bumper in place for more room but we shall see.

current plan is to not pull the radiator and do it from the top.

No need to remove the bumper.
I swapped an entire motor with the bumper in place.

Robert,

I will tell you this, I started out with the radiator in place, and eventually said screw it. If you need a hand, I should be free this weekend.

Thanks for that - and that is what i was thinking... since the system is drained might as well pull the Rad for clearance.

This may be a given assumption but do a good job removing the old gasket material from the front cover surface. It can be a pita if you aren't prepared to do it ahead of time.

basically two wrenches. One for the nut and one kinda catches the studs to hold it in place.

Oh....I've had my fans off numerous times and I don't have a fan tool; just a large crescent wrench.
The RRClassics dont need a fan tool.

Carry on...
