my 86 camaros radiator has an extra outlet hose that is above the trans cooler and under the pressure relief hose. the previous owner put a black rubber cap on it and clamped it the cap is cracked anyone have an idea where i can buy another, what the hole would be and is their a better solution to my problem them re capping it.

 

sounds like your talking about the return for the heater core.

 

o really how hard would it be to run a hose for the heater core?

 

if your heater core isnt hooked up you would just run a hose from the water pump to the core then from the core to the radiator.... if its not hooked up though chances are the core is busted.

 

the inside of that port on my factory radiator is threaded i put some teflon paste on the apropriate sized plug and problem fixed
