thanks for the reply. good news, just the hose ruptured coming from the compressor. when should i adjust the valves, coolant, and does the remaining belts, i.e. fan belt need immediate attention. i believe the car is a euro edition. the heating/cooling adjustments are the rotary dials, not the press button. i hope to enjoy many years with this rare auto.
