Well crap...nicked aluminum heater line

[SnowDrifter]

I thought about it but I thought that the bevel needed to push up into the seal. I might try it and if it leaks go my patch route. Thanks for the input!

Can see the o-rings here. I loooks like it might be fine depending?

I tried it anyway just because I was curious and it leaked. lol I'm glad I tried it though because I would have always wondered. I took it out and put in my backup plan with the piece I cut from one in the junkyard with rubber tubing and hose clamps. It seems to be working just fine and the tubing is snug. Here is a picture of that.

Now on to my next issue... I was testing the heat to make sure all works the back is not. The front works great but the back blows cool air. I let it run for about 30 minutes with the air blasting in the back on full heat but it never warmed up. I noticed that only one of the lines running back there is getting hot. The one that I repaired is warm, but not hot like the other one. I just bought this Tahoe and I don't know if it's wasn't working before I bought it. All tubes have coolant running through them so I'm wondering if the actuator or the controller in the back are bad... From one thing to the next. lol...

One tube is hot

The other is cold

No warm air, correct?

Is the tube warm at the back of the vehicle? You can crawl under by the RR tire and feel. They run all the way back by the frame rail

Trying to determine flow vs. conducting heat from coolant passing nearby

I'll give that a check tonight and get back here. Thanks for the help!

I haven't been home to check this yet but I do have a question. The T connectors for the heater core coming into the engine compartment (where the two relay lines run) are they supposed to be the same, right? They aren't two different types of connectors, are they?

The ones by the firewall next to your trans dipstick? They are 2 different fittings. One black, one white.

Yea, one is 111mm, white, and the other is 113mm, black.

Well, crap...that's my issue. I bought two black ones. :/ . I'm a dumbass...

You can still get with the times and integrate, it's never too late. Black and white CAN live together!

There is always those aluminum ones from Gruven Parts for $75 each. They don't break down the road.
