-Warning - long technical rambling about minor detail.-
Got the trans cooler plumbing done. for now.
Problem is, I'm a perfectionist at times (most of the time), so small details turn into a week long debacle.
I used 5/16 hard lines like factory so I could use the steel inverted flare fittings on trans. Couldn't find 3/8 IF (5/8-18) to 1/8 MPT in steel, bought some brass just in case. Planned to use 3/8 hose so found some 5/16 IF (1/2-20) to 3/8 barb. Then I bought the 6L cooler with 1/2 barb fittings. Ideally I would use AN fitting and braided -8 hose. Couldn't find a -5 to -8 adapter and didn't want to use 3+ fitting to get there. Can get -6 to -8. Also need a 90* bend...
Local Ace HW had 5/16 flare to 1/4 MPT 90* fitting and a 1/4 FPT to 1/2 barb. Amazing, local 2 fitting solution.
But I didn't want to use the 45* flare as it would be the only one on the whole truck and inconsistency bothers me. Summit had 5/16 IF to 1/4 MPT 90* and hose I needed so I ordered and it showed up in less than 20 hours. This at least gets me same termination in both ends.
Ideally I would swap out hard line to 3/8 so I could use -8 fittings, but the bends were tricky and time consuming even without the cab
off the frame. Lines go in between the exhaust pipes and have many bends to optimize routing and distance from hot pipes. Would take a lot of time so I cut and flared the existing lines and moved on.
The elbow fitting had tight/no radius for flow. I didn't want to bend the end of the hard line so it could be removed without pulling radiator or exhaust. So I inspected the hole sizes compared to the 5/16 tubing ID. I hogged them out a bit to match, but offset was tight and short side radius couldn't be blended. The original bores were not full depth so some improvement but nothing like a proper 90* hose end...
So I ended up with this, which resembles something a teenager might construct for a specific purpose.
I want to cram a winch in front of radiator under valence so I kept lines tight. Hopefully an impact won't snap them off, but can't really plan for stuff like that, although the AN setup would be better....
Right after finishing up I had to get to core support bolts, glad I left some room.
I then farted around with a hose support for the long side. Could have spent another $100 on AN stuff and a bunch of time, but not sure there is any measurable benefit.
