Leak

[bigdaddyyukon]

Well, I found , well. I think I found were it's leaking. When I bought the truck I seen this aluminum tapon this line and thought nothing of it. I thought maybe protecting the wires. Well, my son mention to me to feel behind the tube. Yes. It was wet. Constantly. So I will be replacing the tee and go from their.i hope that's the issue. If it's not. It needs replaced anyways. Talk about band aiding a problem.

That looks like the heater hose T fitting st the firewall that’s a common problem. If it is, I’d plan on replacing both of them since they both tend to get brittle. There’s a black one and a white one I believe. There’s a thread on replacing them here. I haven” t done mine yet but I have both parts at the ready.

easiest way to do that is too take a pair of long needle nose pliers and break the small thin black plastic off behind the white clip makes the job 5 minutes instead of try to use some special tool that NEVER works and fighting with it for an hour, in 20 plus years they haven't come up with a better design I guess for assembly line work it makes it super fast to assemble.

Exactly what I did. They get so damn brittle.

X2......

Funny thing is the black and white connectors are interchangeable...

Not sure why they made them different colors other than to differentiate which hose goes to which side of the heater core.... which shouldn't make any difference at all. The heater core doesn't care which direction the coolant flows through it.

Either way, I digress... I have read where some people theorized that the black plastic material was less prone to cracking and getting brittle than the white plastic material.... or perhaps it was the other way around... anyway I think when I did mine I used the black ones on both if I remember correctly.

If I ever do them again I will probably get brass fittings and try to make my own.

Now that is something Gruven should build.

Why not just bypass them totally? A few guys on here have done that.

Quick question on the Tee, what are the metal lines going to that go off to the side instead of the heater core?
