Hi all. This is regarding a Jetta ABA engine in a Vanagon.

I intend to replace 2 coolant flex hoses on my Vanagon with 1.25" hose
from my local semi truck repair shop. It's on order. It's application
may be for a semi truck heater core circuit. A similar 1" hose I saw
at this shop took a large radius 90º bend which for my uses, would be
ideal.

IF this new 1.25" hose is intended for heater core circuit, would
(possibly) hotter coolant straight from the engine cause it to balloon
out or otherwise fail prematurely? The longest piece would be about
3'. The flex hoses I'm replacing have a thinner wall construction.

If this hose is ok for this application, it might be of use for other
engine swappers requiring custom hoses. It might eliminate some
cooling hose unions.

Neil.
