This is an alert! After a SERIOUS failure of my plastic tank radiator (blasted thing just blew apart at 50 mph on a freeway) I want to alert everyone to the reality that this lousy plastic piece of german junk is likely to blow apart at any time. Please watch your radiator's age and spend the $1000 ($500 if you are smart and buy it on line and get some nice person to install it for you for $50) it costs to replace it once in a while before you have to replace a $4000+ engine. This is especially true if your engine mounts have ever failed (so I am told by my dealer, after it was too late!)
