I have read where the intake coolant leak in 96 and later Vortec engines is a common problem. Leaks are common at the quick coupler which is poorly designed?
My Bro in Law has the symptoms on a 99 Burban , coolant leaking around the intake manifold where the funky mis- engineereed pot metal quick coupler is the culprit. (The metal end pre bent coolant line where it goes into the intake).
Has anyone changed these out.. > perhaps to a better solution?
I am thinking this coupler is going to pop right off and leave the threads in the intake because of corrosion. The couple takes a 1 1/16 socket and I know it will break.
Anyone had a simialr problem and how did your fix go ?
Can it be done without re-tapping the threads?

Thanks

Looking at changing it out in the AM.

i change these out all the time,i keep an easy out and tap in the drawer with the new couplers. you could switch it over to a nipple with a hose clamped hose.

You wouldn't have the size handy would ya on an adapter size?


NPT I assume? I won't have a tap but can drill or pick it out..
ya think?

have you ever got one out without breaking it?

maybe one out of 40. it generally snaps off when you try to take the hose off.

There is a thread somewhere in this Chevy section on this. I believe it is 1/2 NPT.
