Water pump too? (w/timing belt change)

[atcovan]

Here is a how-to

Yep thats the how to I'm going by. (Although I'm going to make an even better one).

I even bought the same belt he used.

He re-used the waterpump, just used a new gasket, and thats what I'm gonna do.

A new water pump is another 50 to 100 bucks away, and you have to remove more stuff to change it, so I'm gonna wait till next time.

The water pump is under a lot of tension, so it's prudent to go ahead and replace it. Well, that's what I planned to do before a truck came along and totaled my car! Anyways, why open it up twice? I paid $73 for a new pump from Rock Auto, along with the Gates belt, idler pulley, tensioner, new metal thermostat housing assy and hoses. If you're still riding around with that crappy plastic housing, change it soon.

i have never seen a water pump used as the timing belt tensioner...

Actually, the tensioner is a separate, but fixed, spring-loaded pulley componet. The water pump is rotated for proper adjustment. There's no need to mess with the cam timing gears.

If I can squeek the pump out as shown in the write-up then yeah I guess I should throw on a new one.

If I can only fish a new gasket on the back of it then so be it.

Freaking local auto part stores are rip off priced...found one unknown brand at napa online for $135!!!!

And another AC delco one from RockAuto.com for 40.03 shipped to my door.

-- Sorry to hear your car got totalled dude. Going to get another?

I didnt opt to buy your timing belt stuff... but I might be interested in the metal thermostat housing.

I ran out of $$, so ended up with a '97 Buick LeSabre, actually a really nice car and I get 30mpg hwy. The waterpump 'gasket' is an o-ring. I'm willing to part my parts, so to speak. : )

Right...O-ring.. I ordered that (.75c) and The Contitech timing belt kit for 101.75 from www.partsgeek.com

If I go buy the waterpump it'll probably come with a o-ring too.

The service manual mentions something about a grease for the o-ring called 'lubriplate'.
Is it just grease? wonder if the dealership has it and if it comes in a small tube?

Hmm

in my experience "greasing" an o-ring usually means so it wont tear for install, and help stay in place. i typically use whatever it is going on. straight coolant for the cooling system, oil for the oil system etc. and never had any problems. i have also used ultra black to hold them in place if they fall off a lot trying to get a part into a tricky place..
