Re-cored radiator install - yes. Alarm system figured out so car will start - yes. Transmission cooler line fittings on grill side of radiator leaking - unfortunately yes. How do you get those 90 degree fittings clocked tightly into the radiator and in the right direction? I used some good sealant but apparently it didn't work. Can I use teflon tape on those fitting? I think the radiator has been in and out of the car more that I have since I bought it.
I was so close

When my radiator was upgraded to the cold case, the curved lines that run around to the front of the radiator were put on first. Then they were attached to the long lines running to the transmision on the side of the battery. That is the easiest way to assure they are on straight.

For me it was easiest to put the 90* fittings on BEFORE I put the radiator in. That way I can tighten & clock them to the correct position to meet up with the cooler lines.
As for the fittings they should seal themselves. The thread should be self sealing(similar to the way the brake lines seal). The brass fittings are cheap enough if ya need to buy two new ones. Just be sure to get the correct thread type.

That is how it was done on mine. Sorry I left that part out.
you are correct ,But the OE is NTP Im about 99% sure. It would be almost imposable to get a 5/6 inverted flare 90 to bottom and seal at the correct angle on the 25thousand turbo Buicks belt in 87
This is a pic os a OE radiator and fitting clearly 1/8 NTP

THensley, I'll try the Loctite 545. To confirm: If I get the fittings in there finger tight, I can get up to another full turn? That would be great.
Do I have a little "wiggle time" before it sets up if after putting the radiator back in things get bumped a bit when re-connecting the lines from the transmission to the hard lines that wrap around the radiator?

please confirm your OE has 1/8 NTP as pictured and not 5/6 inverted flare, If someone changed the OE cooler its posable to not be NTP.
You will have plenty of wiggle time 545 takes hours to set not minutes
My favorite goto For NTP is Loctite 567 and with 1/8 -1/2 NTP you can get 1/2-3/4 turn and maybe a full turn from finger tight.
It is also a very good sealant , it needs to be snugged down tighter than the 545. 567 is a sealer and thread lubricant. 545 will bond similar to a locking formula creating your seal.
Locktite products are $ but they're not just a sealers but take the science two steps forward past hardware store products.
