radiator
hi I have a 2006 Winnebago journey C-7 cat. 50000 miles I have no over heating problem but should I just drain the radiator and refill with new coolant.? rudi

Our coach is 18 years old, the coolant filter has been changed once, the fluid never, it still tests good, still is a clear green. and will be changed when it shows bad.
Tom,
Yes, I assume you are using the three way test strips.
They test for:
Freeze point
SCA concentration
pH
It is often the pH (coolant becomes acidic and starts "eating" coolant system components) that triggers a coolant change.
