When was the last time the coolant was swapped? Also, you do know about the special procedures for the 722.6 tranny?
S'up with the glow plugs on the 606 engine? Jeez, ours didn't make 50,000 kilometers. It was glow plug troubles that made my wife ditch the car. She got tired of it running like crap.
I LOVED driving the car. Torque!
