If the engine is near overheating, and the fan is not turned on by the thermoswitch, I would not trust that the switch that cuts out the compressor at a _higher_ temp will work. In my old-style 900s (so far, an 82 and 83 Turbo, and a 91 S Convertible with an auto tranny) I rigged up a switch to turn on one of the fans at will. The second fan still comes on when the thermoswitch activates, but the occasions it has to do so are much reduced in mountain or city driving. --------------------- John R.

This means that the usual trick of turning on the fan by turning on the AC (in case of near-overheat) which engages the fan while the AC is running does not work with a 900?
