1973 270 heater hose diameter?

Unread postby emaxon on Tue Aug 01, 2017 10:05 am

I searched the forums, found a documented dash heater core swap w/ dead photo links, mention of 5/8 barbs there, but no mention of what diameter hose is used for the rest of the cooling system + rear heat. Sure, I could drain, disco, measure, but I'd love to have a roll of the correct diameter ready to go before ripping into it. The hoses (mostly red) are so old and swollen, I can't really tell whether they started life as 5/8ID or 3/4ID. Anybody know? Thanks in advance, Eric.

I have a 76 but dont remember the hose size. I have a box of it in the garage somewhere and will let you know. I replaced all the hoses 2 years ago.
