    Anyone have such an item ? A cheesy fitting corroded off and expelled all the coolant yesterday. Today I got the right size E-Z out...and it split the boss on the manifold. Two problems...dealer wants $800 ! I need to get this thing going without fail cause it's my only plow truck. It's a 1999 5.7/350 and it must be from 1996-? vortec heads. :cry: :realmad: :help: :angry:

    My Tahoe did the same thing. I did not use an easy out though. I ground a tool down and tapered it where it made a good bite into the broken fitting. What boss did you break. Post some pics.

    No pix right now, but...the cheesey clip in heater hose thingamajigger fits into a device that threads into the intake above the #2 cylinder. That heater hose fitting is what broke, and subsequently as I was trying to remove the broken off thread part with an EZ out, the intake split around the threads . Dammit !

    Yes I know which fitting it is. I was wondering how you split the intake. Check e-bay for an intake. Too bad you do not live closer I could TIG it up for you. The intake has to come off regardless.

    Dorman has the '96-'00 lower Vortec intakes brand new for much less than OEM price. New ones around $350.

    i guess you learned not to use an ez out just chip out the old pieces and chase with a tap

    Searchable by state/province. Even does cross-references on the fly (what model fits what model).

    I've been searching for the aftermarket version, but it looks like nobody stocks them. Also looks like I may have to plow tonight. FUBAR !!!!

    Unfortunately I found your post only after I returned from a junkyard with one-they got me for $150 for just the lower. I don't have the broken one off yet, but the one I got has the worst casting I've ever seen. Several of the intake ports are twisted.

    I don't know what the dealer has, but Fel-Pro has an updated kit for these. Much better than the stock plactic gaskets GM used for way too long.

    Fel-Pro part # MS98000T

    The techs at the local GM dealer wont use the GM gasket only the felpro.

    why cant you drill it out and heel a coil it ????

    That might have been an option to begin with. The threaded portion broke/crumbled below the surface, and I got a big easy-out which grabbed really nicely. Because of the coolant which had been trickling out of this fitting for years ( so that's where that coolant smell came from...) this thing had the grip from hell on the aluminum and it cracked the manifold :angry: :cry: :alien:
