Would placing heat shield material around the coolant tubes do
anything to prolong their existence?

Product like:

I put something like this on my engine's new fuel hoses that sit above
the engine to the fuel rails. I expect it to help prevent the heat
from drying out the rubber hoses over time. I figure one a year from
this point I will take the sleeve off to inspect the new hose and see
how it's doing.

I was thinking that maybe a product like this could be used to protect
the sensitive coolant hoses in the engine bay.
