Can I use PVC in a coolant hose?

[sailingfc at dslextreme.com (DY Wong)]

I don't think the PVC will be good.  I think there is a PVC for hot water,
call CPVC.  This is made for hot water in your house.  House water from a
water heater is not boiling.  The coolant in a typical engine can easily
past the boiling point. And the underhood temps could be even higher.  I
guess one way to test this is take a piece of PVC and throw it into a pot of
boiling water for a while and see if it gets soft or changes.

Good Luck.
