I thought I would remember where they went, must be getting old! LOL

I have a 302 from the 70's, there are two outlets on the water pump for heater hoses, and one on the thermostst housing. There is a fitting on the manifold and two heater hoses on the firewall (in a 56 f100) an upper hose and a lower. Anyone have any diagram, or can anyone take a look at their smallblock and bail me out??

 

the thermostat housing hose goes to one of the water pump nipples. its the bypass hose(a 90* molded short piece of hose.) the other water pump nipple goes to the firewall. the other hose from the firewall goes to the top of the intake manifold which usually has a 90* hose fitting on it.

does it matter which nipple to which heater hose?

 

Anyone have a diagram?
