70000 kilometers on my 2000 2.0. Driving on highway today around 130km/h or so, and notice temp gauge climbing past 240. Oil temp was OK..stayed around 220. Pulled over and opened hood to the sweet smell of coolant. Had it towed to mechanics shop. He's not in on Sundays, so out of curiousity, I pulled the thermostat and looked at the water pump. Looked OK, but when I put my finger in, the impeller was hard to turn and I felt little bits of broken plastic. So anyway, that was just a rant, but does anyone have any idea WHY VW would use plastic on such an important part?
