anybody know the inside diameter sizes for the heater hoses? i have a bad heater core so i plan on bypassing the heater core by looping the 2 heater hoses together.. anybody know the size of it?
 
I happen to have new heater hoses in front of me. They are for a 2G, however. They should be the same for a 1G.

Inside diameter - 9/16" or 15mm

Outside diameter - 1" or 25mm

Heater Core Bypass Hose

--------------------------------------------------------------------------------

Got tired of the primitive Climate System Flapper leaking Hot Air 24/7 even after fixing Cables & installed a bypass hose on the Motor that "jumps out" the Coolant hoses to the Heater Core - Gates P/N 18889 worked great, had to cut the 90 degree bend off one end & trim the other end to fit but it's pre-molded into a nice squared off "U" kinda shape - There is also an obsolete Gates P/N 28281 that is some badass Heater Hose with a spring inside it to prevent kinking when put in a "U" - It's actually called Heater Bypass Hose. I actually have real unheated fresh air in the car now.
 
Anyone know of any place to get replacement aftermarket hoses for these?
 
oh ok. How about the other hoses? LOL... I see them plain as day when I open the engine bay. Just trying to dress up, but I won't get cute.
