Yes, except that any component failure should be limited in its effect.Good points Buttercup and David.
I retract what I posed re. manufacturing decisions and stand by my suggestion of it (at least the later 'fail-safe' type) being a great design.
To add to/paraphrase what David said, if something is designed to last and perform well for a defined service life to satisfy the higher level system SoRs..... let's say about 10 years in this case...... and it does just that, then that is a great design.
Any service life beyond what it was designed for is a bonus.
I have a good s/h one ,$100 plus postageIt seems impossible to find David. Thanks for having a look!
The connector to the radiator on mine is stuffed, is there anyone sround who makes up hoses?
