Two pipes? - Ford Forums

Just going over my cooling system after installing the water pump and i get to my radiator.
There are two pipes coming out of the top of my radiator where the filler neck is. (should i have two?) Which one of these does my overflow pipe attach to. One comes out where the base of the rad cap sits and the other is a bit lower.

i am not sure what the 2 pipes are for but the overflow tank deffinetly goes to the one right on the base of the rad cap.

You should only have one large pipe that alows the hot water go into the top of the radiator, underneath the radiator filler neck is a small overflow outlet the lets the water escape into the overflow bottle. There could also be another 2 outlets down the side for auto trans cooling

This is not mine but its the same.

I'll try that again

351w · 10-04-2003, 22:20

that second tit on there is for decoration !
it actually serves no purpose because if it had a hole in it, all your anti freeze would leak out.
