Intake Manifold..... anyone? anyone?

Was your original leak?? on the rear of the engine or the front. I am glad I resealed the Intake manifold on my 99 tahoe. It was a mess.. I cant beleive it was running in the shape it was in before the re-seal..

If you need the visual (a top or engine view) bolt tighten sequence, Give me an e-mail and i'll send to you in JPG format or BMP format. i'll include the upper sequence too.

how do you know it's not pumping? It's not moving externally? No pressure build up? No hot water entering radiator? Someone Correct me if i'm wrong but isn't the water pump shaft/propeller a solid piece. If its turning on the pulley the impeller should be turning inside.Did you maybe block any of the passages and forget to remove upon re-install.

O.k. 10 Hrs. later and lower intake manifold gaskets installed I have no leaks....
I have one thing to say. Beware of the heater hose coupler at the front pass. side if the intake. Extremely brittle!!!!!!!!! I barley put ant torque on it and it snapped off.....
It was a good thing b\c it made me have to remove the lower intake to remove the remaining coupler. When I got the intake off I saw that the gaskets were in bad shape if they were not leaking they would be soon!!!!! Thanks for the help guys...

Go for it! I was also ready for the dreaded intake fix when I found it was only the water pump! And now the coolant is a pleasant green!
