    Heater Hose Sizes
    « on: April 14, 2010 - 09:34:27 AM »
    What is standard on a small block.  I've been running without a heater core for so long I can't remember.  I just reworked the interior and installed a new heater core and I can't remember what size the heater hoses are.  Any help is appreciated.

    most heater cores have a 5/8 & 1/2 nipple , 1/2 would go to the manifold & the 5/8 to the pump

    for some reason I thought it was 5/8 and 3/4" lines.  I couldn't find a 3/4" fitting with a 3/8" NPT thread like my manifold has.
