4+3 Coolant Line Replacement
Anybody ever replace their OD Coolant Lines with AN hose? Are there adapters for the OD and Radiator ends?
Thanks.
Thanks.

There has to be adapters that could be used to go from a flared end to an AN end. Same at the radiator side. IIRC, the hard lines use a flared connection with NPT threads.
You could check with companies like Aeroquip, Earl's, or Summit Racing for adapters. Hose is sold in bulk so it would be easy to make the correct length hoses with straight or angled ends.
I'm going to do a similar thing for my 87 when I add a PS cooler and get the pump rebuilt.

Should the steel lines ever break or corrode to where they start to leak, the chances are that it will be difficult to find OEM-style replacements. A shop could custom bend steel lines and flare the ends, but using something like AN fittings and hoses makes it a DIY project.
It's even easy at that point to add a stand-alone cooler for the OD unit. And if the trans cooling portion of the radiator ever fails, using flex lines and a separate cooler would be much cheaper than a replacement radiator.

My thoughts exactly, George. Also in my case, while attempting to remove the radiator, I find the lower fitting seized. Not in the rad, but fitting seized to tube. Don't want to turn the fitting too far for fear of kinking the tubing without an escape plan.
