I just ordered a pair of coolant hoses that directly feed my nice new
radiator in my '84 vanagon.  The hose that has the bend in it seems to
be slightly incorrect. The side that connects to the rear metal lines is
too large in diameter. The hose slides freely onto the rear metal line.
 I suspect this is because the hose I got is intended for use with later
model vanagons that have the plastic lines that run the length of the
van. They area probably slightly larger in diameter than the metal ones?

Anyhow, I clamped it on well (maybe I'll double clamp).  Do you think
this will suffice?
