Reply to "Jtaphorn Cooling system modification"

Hi..all nice discussion, not there in my rebuild but close (need some welding on the Fluidine Radiator (2 outlets on right side) posts on the cross bar first).

for now 2 questions:

quote:

if you are considering making revisions to the coolant system plumbing then increasing the size of the radiator outlet plumbing to 1-3/4" OD is where to begin your effort.

1) Well in my case the tubes below are today aluminium 35 mm = 1 3/8 ". so where is the cross over from 1 3/4 to 1 3/8 then?
(guess at the pump tubing/Rubber..?)

and...

2) the picture from the sticky and in the note indicates to me the HOT side of Water (comming from swirl Tank) goes into the lower portion of the radiator.?? - My older Fluidine has kind of 2 horizonal layers the fluid needs to go through.
- Hot Water on top outlet or lower outlet? Top down or bottom up..
(I understand hydrodymanics, ..hot water moves up..smile)
- THEN the Thermo switch needs on the HOT side (assume now lower side?)
.......just to confirm...

sorry was not clear to me..
