    Default Heater Hose size

    Does anyone know the inside diameter of the heater hose(s) that come up out of the tunnel, and run to the heater core? They look to be 5/8" and 1/2" return, but unsure, they may be the same (i think the combination of my eyes, hanging upside down, and blood pressure is making figuring this out somewhat difficult).

    Was having A/C issues - which is driving this troubleshooting - but today, felt the supply and return under different settings of the heat/AC controls - things seem to be in order as the temp only goes up at the heater core connection, and coming out the return after adjusting controls to heat. AC still not operating as very cool output, however.
