RADIATOR HOSES and HOSE CLIP (HOSE
CLAMP) ASSEMBLIES
Radiator hoses were either predominantly black
with a red longitudinal stripe which was generally
installed with the red stripe facing upward or all
red (a small percentage of production).

The black hose had a coarse spiral wrapping
pattern which is quite visible. The pitch (width)
of the spiral pattern from the mold varied. The
pattern could be in either the right hand or left hand
direction. The red hose had a "U" pattern on the
edge of the coarse spiral wrapping pattern which
is quite visible. None had a Ford script imprint.
The two lower hoses were 2-3/4" long. The upper
inlet hose was 6-1/4" long in 1928-29 and 8-1/2"
long in 1930-31. Beginning in early 1930, a four row,
oblong tube radiator was introduced for heavy
commercial vehicles which required a 9-1/4" long
upper inlet hose.

Both radiator inlet upper hose clamps had the
screw on the top side of the hose with the head
toward the driver's side. On the radiator outlet
hose nearest the radiator, the clamps had the screw ~
on the driver's side with the head facing upward.
On the radiator outlet hose at the cylinder water
inlet casting, the clamps had the screw on the top
of the hose with the head facing the driver's side.
Original clamps were either dull zinc or cadmium
plated and were not stamped with size numbers.
The inlet radiator hose clamp assembly round
head screws (No. 10-24 x 1-1/4") and outlet clamp
screws (No. 10-24 x 1-1/8") were secured with
square nuts (1/8" x 3/8") plated to match the
radiator hose clamp assembly finish.

The red stripe on the repo hoses is too red. I always paint over it with red rustoleum primer, (a much better color.)
