You should replace those tee's and the heater hose nipple where it is crimped. They are 3 separate parts and a major PITA. But if one of them let's go on the road that is worst, bad news bears.

Ah I see! They are the lines into the heater core right? Other end of the hose goes into the water pump. Might just do a full on coolant swap while I'm at it

I also have a billet stall but he wont reuse it because it will void any warranty for the reman so, I need a new converter. Which I'd send mine to get it serviced but they're out 2 to 3 weeks.
Yay
Sorry to rant

The timing for your torque converter may not align with this rebuild. But if I were you I’d still consider sending it in to get serviced, refreshed and then sell it as new on here. Document the refresh service, save receipts, and I bet you could easily. And would help Cecil some funds from the rebuild…

Yeah, it's kind of a bummer. But I agree, I'll definitely send it back for a refresh and keep all the paperwork for it.
If I can catch my mechanic at the right time, he may be able to put it back in as long as he's not tied up too much.
Otherwise, I will post it up.

So for some reason my Bose system is messed up, I only have sound coming from the a-pillar tweeters and the r/f front door panel and the sub in the console. No sound whatsoever on d/s front, 2nd row doors, or d-pillars in the back. Any thoughts from you audio guys? It is a stock non nav head unit. I think it has been like this for a while I am just getting into trying to diagnose. If it is not something simple I will rip out all the factory and go full aftermarket.

I did remove the rear audio control panel in the rear of the console. Don't know if that has something to do with it or not.

@mikez71 @j91z28d1 any thoughts?

If you have a tech2 you can test the amp, channel by channel it sends a tone to each one

And that rear control i believe does have something to do with it, try plugging it back in

Filled the washer fluid and changed out a couple wire stand offs that were broken, salvaged a few decent ones from the junkyard, then replaced a couple sections of wire loom purchased a big box full of loom and shrink wrap for like $30-40 off of eBay a while back, these clips you can't get separate you have to buy a wire harness to get them
