Default Heater core hose question

Hi to all,

My hose from the heater core to the thermostat let go on my 1974, L48 with Air condition. Can any tell me what size hose it is???? The one I need to replace is a replacement and the size is not visiable on the hose. Thanks for the help

Are you speaking of the hose to the intake manifold?

Water pump hose is 3/4

Default Heater Hose Headache!

The correct hoses are molded where they connect to the heater core, if you use hoses from the auto parts store they will kink, you have to buy them from one of the sponsors. PG.

Thanks for the replies. I ordered the pre-formed hoses from a Corvette supply house. My next question is how are they routed, with the air condition compressor? If someone could send me some pictures of a stock L48 with air conditioning, so I can see how the heater core hoses are routed I would appreciate it.

Thanks
Tom
