What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Rocket Man]

all you have to do is take the clip off and the tube slides right out, it's a quick release. just like the gas cylinders for the hatch & glass a new radiator will come with new clips.

Even better is installing them- just push then in until they click.

What is that plug out of? Doesn't look like an engine oil plug. Them shiny metal chunks look like timing sprocket teeth.

Dammit. What’s that plug out of? Front diff?

Rear diff.

Rear diff.

Gov-bomb?

And if you have the tool, (Lisle makes a small cheap one) it's almost as easy to remove. Just an 1/8th turn of the tool and pull the tube out. No having to remove the spring clip with a pick and hoping it doesn't go flying somewhere never to be found!

This fitting type is called a Jiffy-tite fitting and is used on just about all makes/models of automobiles.

If you're talking about the stock hardlines that run to the rear heater core, they should have a barb already on them. That's how they stay in the factory quick connects.

They did. Buuuuut I cut them off to make room for the aluminum Ts :-/

That's cool! I've never seen those before.

I rub a shop rag around the the fitting to snag the clip and capture it in the rag.

Rubber gizmos? Are you talking about the plastic covers that go over the spring clips that hold those lines in?

@Doubeleive will regular needle nose work, or are C clip pliers needed?

Oops, finished reading the replies and had my answers.

ya anything will work I prefer to just use a small flathead screwdriver or a pick tool with the 90deg tip doesn't take anything special

You don’t happen to know the Lisle part # for that tool do you? The connectors on the side of the trans are the ones I have trouble with and that tool would be nice.
