I think that a radiator failing below 150K miles is rare...and can only recall of one radiator neck failing. My gasket failed, as I said, around 180K...11 years old at the time. It might be age and miles, but I think it fails catastrophically rarely, and thus I'm not so emphatic about it needing to be done preventatively (or preventively). Therm(stuck closed), ET, WP...when they go bad, the consequences are immediate and severe.
I'm so depressed. No one wants to come see me in NYC: Sat, Oct. 8, 6 p.m. at Greenwich Village Comedy Club.
