I had a catastrophic heater core failure in my 1993 940 Turbo Wagon. (~222k miles.) I thought it was just a tiny leak, and was heading home (4 miles), when the windows steamed up very quickly. Temp gauge was fine, then less than a mile later (at ~40mph) the temp gauge was pegged out at the top, so I shut it down and got towed home. As I've been working on the heater core, there is a LOT of coolant inside the car. (Carpets saturated, inside heater housing is covered...)
I am trying to decide what I need to look for when I next get it running. If you overheat a B230FT, what tends to break? I am contemplating pulling the head to check for warping. Would that tend to happen? Head gasket failure? What would you look for?
Thanks!
