Heater Core Help.

Does the small hole go at the bottom or the big ? I think the bigger hoe would be at the bottom but what's right ?

Thanks for any help.

They usually have the small(5/8) on the bottom and the large(3/4) on the top. That way the water enters the bottom and exits the top and the water is pumped through rather than gravity fed. John

Sweet.

I have the 3/4 coming out of the intake and the 5/8 out of the water pump. I just figured that looked good. I did not think much about the correct way of routing them until mow. Glad I have them hooked up right.
