Hey guys I got an 85 Iroc with a 305 and have been searching for the 2 hoses that go from the radiator to the heater core and the heater core to what i believe is the throttle body. I know they are 2 different size hoses because when I bypassed it I had to put an adapter on. Does anybody know what the technical name for these hoses are to search for them online or what auto parts stores might have them? Any time I have asked someone they have looked at me like I had 2 heads. Any help would be greatly appreciated, thanx.

 

Its just called heater hose. Most of the chain auto stores should have universal heater hose in stock, just know the diameter you need and then you just cut it to length.

I did a search and it looks like Gates still makes some of the molded heater hoses that have all of the correct bends and curves.

 

From the radiator?
