Help with leak

In my defense you can read that I didn't see the "T" connection to the heater hose, and those aluminum tubes appear much as an A/C tube would. Large SUV's are out of my league apparently. The advice I gave you for an A/C system was spot on accurate.

Our Denali had two plastic quick-disconnect T-fittings/Y-fittings at the firewall and then two straight plastic quick-disconnect fittings that led to the engine. One ours, it was one of the straight fittings that cracked and leaked (fitting was 2 years old). Internet search shows this as a common issue.

To me, the plastic fittings, and quick-disconnects are not a good engineering idea. So many posts on Internet of them breaking or leaking. I guess old-fashioned metal hose barbs and hose clamps are too old-school.

I'm here for the party
many fwd chevys come with plastic elbows that connect the water pump to the engine. the main issue is the O-rings get stuck but then if you apply pressure you'll break the elbow. when i didnt some intake work on my imp i knew this would be an issue and got the aluminum ones. swapped them out with and ended up breaking one of the plastic fittings. now that i think about it if the o-ring gets stuck anyway it might be better for the elbow to break vs the water pump.

Back in the late 1980's GM tried doing the same with the heater core but they leaked way too often, so they went back to a full aluminum-alloy heater core and tanks. Changed one out of a 1988 C-2500. Thankfully I was able to remove the bottom section of the climate control box without ripping the dash apart. New unit was all aluminum-alloy and tubes.

Yeah, my brother-in-law watched one of Scotty's videos on cleaning a catalytic converter with lacquer thinner.
He set the car on fire.
That set the garage on fire.
That set the house on fire.
At least there was insurance, though not for all the possessions. Mrs. Cusser is one-third owner of the remnants....
