Will: Please tell me there'* only one intake manifold on Bonneville'* before "95. I've only done our '98, but I've been telling people there'* only one manifold piece on the Series I, but maybe I'm mistaken.

(edited -- or is that a little spacer manifold on the bottom?)

(You're right on, of course, about that lousy little piece of barbed plastic coolant fitting on the left side of the manifold that should be replaced with a metal one any time you're near it. Can cost $$$$* if you don't get on it -- I know)

There is a upper and lower intake manifold. There hasn't been a one piece intake manifold since sometime in 87-91.

But, please, no more off topic coments.

Hey all quick question. How long does it take to do the water pump? I do have to remove the mount. Also where is the best place to support the engine?

Please edit your profile and put your year and trim level in your signature.

The water pump should take 3-4 hours for a first timer. Support the engine with a jack and a block of wood to distribute the load underneath the oil pan (not the trans pan).

Pay close attention to the lengths of the bolts you remove from the water pump. I suggest as you remove them, you put them into the new water pump sitting beside you.

Then as you get the old pump out, move the bolts over to the old pump in the right sequence while you install the new pump.

The torque-axis mount bracket on the engine side can be difficult to remove. Patience and a breaker bar will get it done.

Ok pinpointed the leak. It is leaking right by a bolt. So under the advice of a good friend who has extensive auto knowledge we used some of that pelletized stop leak and it worked. Our guess is that when hubby bottomed out the car he jolted the water pump and messed up the gasket but since this is working it saves us over $100. Which is a bit more than we can afford right now.

Ps: If hubby had listened a week ago to his friend the car would of already been up and running.
