LS7 Top Coolant Hose Sizes

[Swiss_Toni]

Could anyone help with the sizes (inside diameter of hoses) for the top engine coolant hoses on a LS7 installation?

1 & 2 are 32mm
3 & 4 are 38mm

There is an aluminium reducer joining the two.

My advice - just buy it all from the factory and save yourself the grief.

Thanks, I've got a few different lengths of hose and elbows in stock, I just wanted to check if I had any of the correct items before ordering.
