2011 PPV..What part/function is this? noticing leak

[ramchol76]

When I was investigating wet floor in passenger side (happens while raining), I noticed minor very slow leak in the pictured aluminium pipe coming from heater core hose (yellow circled picture). i believe this may not be the cause of passenger side water leak, but have couple of questions on this leak

1. what this T junction aluminium pipe heads to.. rear end HVAC?
2. should I change the T connector to fix the leak?
3. any relation with passenger side carpet wetness?

Thanks

Yes, that is the hose that goes to the rear heat exchanger.

The plastic T’s are known to fail. Could be related to water in your floor board.

This company sells billet replacement tees. Or the GM ones at RA: https://www.rockauto.com/en/moreinfo.php?pk=10704844&cc=1442911&jsn=3483 or the Gates ones:

You did not give the year, make or model so I just guessed at it.


I recommend that you put all your rig(s) info in your signature so we all don’t have to guess at year, make, model, engine size, trans, rear axle locker…….etc. Makes it way easier on all members that attempt to help, to have that info right up front.


If there is any other info, like upgrades, mods or recent mechanical/maintenance work done, that would be helpful in any post as well. Too many times a question is asked by the poster and after about 10 responses we find out that the poster has done recent work to attempt to fix the problem or work that was done that SEEMS not related to the problem.

Like Wade said, these are known as weak spots that DO leak.

Gruven builds these...

Buy once, cry once... IMO

Use these and never have to do them again.

My 2 bits.

But with what type of clamps on the hoses?

Whatever type your little heart desires... or your wallet dictates.

I was researching them this morning. My heart desires OEM style spring type ("constant tension"). But my wallet dictates the EFI screw-type. I'll probably end up grabbing a buttload of OEM ones from the salvage yard.

Knowing Chris, he would have to call the manufacturer and find out if the spring rate on these clamps, and there metallurgical composition, is the same or better than the factory clamps and then figure out what percentage better, or worse, they are.

I saw those and was tempted. But I'd only be able to use maybe two sizes out of it. They're all too small. Thanks for the link, though!

Judging by the reviews, I'd say their metallurgical composition is far inferior to those used by the factory. How inferior expressed as a percentage? Lets do the math:

Worm gear hose clamp + 5/16" driver = Done and moving on

Does the small blue hoses and clamps come with gruven t connectors?

Yes and the blue hose is silicone.

Yea, but you can always tell us about it again so we can chuckle.

I sat on the engine block while Removing the number 8 spark plug. Put my elbow on the heater hose for leverage. Pop goes the weasel...
