Huh? There is a right way to do them. 5/8" hose from the intake manifold to the bottom of the heater core. 3/4" hose from the top fitting to either the radiator or the water pump depending on what you have.

I know its a dumb question....But the reason I asked was, I hooked everything up as follows:
Top core 3/4 to the intake....Bottom 5/8 to the nipple on the water pump. I did it thinking that was the way it went. I started looking at pictures on here and see they are the way you describe. I'll have to go buy more 3/4 heater hose to change it. Thanks!

Hey Fastback,
To be correct it needs to be the way da-burb posted. While it will work hooked up backwards, its not the way GM intended it to be setup. The hotest water in the engine goes out the 5/8 hose on the intake and goes into the lower nipple on the heater core also 5/8. Cooler water returns from the top 3/4 inch nipple to either the radiator or waterpump which will also be 3/4. When dealing with hyrdaulics or any kind of fluid pressure system, the return line will always be the larger line. Thats why one nipple is 5/8 and the other is 3/4, they didn't accidently do that! Jeff

not as hot? Nothing you'll ever be able to feel...no damage either.
