Isn't it really because today's engines aren't made to overheat and live?
In the 'old days' when you overheated, you fixed the problem that caused it then refilled the system w/ coolant/brought up to temp/topped up/capped off and were on your way.
Today's engines have a multitude of ways to lose coolant and if you let them get too hot, head gaskets pop and you're done as they're often never the same again even after repairs.
A few weeks ago @ less than 60 thou miles, my wife's Caravan was running slightly warmer than usual and looking underneath @ shutdown (when hot and pressure up) I saw a thin stream pissing from the WP bipass pipe.
Lucky timing as she was about to hit the road and would surely have overheated on the hiway...when I swapped the part, it was leaking right where the support tab is welded on also the pipe waaay too thin a gauge for the use.
So again, some parts are made to fail after a "manufacturer's calculated period of time" and lose coolant then overheat causing much more serious damage than what started the problem in the fist place!
And what do we sheep do then, swear we'll never buy a damn Chrysler or whatever again and go buy something different....and so on.
