Asked by black_saab Sep 09, 2012 at 06:38 AM about the 2006 Saab 9-3 Aero Convertible

Question type: Maintenance & Repair

any ideas. noticed over a week ago my temp gauge is displaying above the normal running - just
below half way. discovered rad fan and A/c compressor wasn't running.

changed resistor pack on rad fan and this is now working. ( overruns when engine switched off as
normal etc ..)

changed condenser and re-gassed A/c. this is also now working ok.

but gauge still displaying above half way point. with roof up or down ( A/C on or off) it still displays
the same. compared gauge with OBD temp on bus and seems to be reporting correct values.

gauge moves to above half way point within 10 mins of driving and remains constant. i.e. driven for 2
hours and now moved much ( air flow might have a helped a little.)

You might want to have someone actually look at it. If you keep replacing parts that aren't causing the problem, the problem will still continue to worsen until you end up with an expensive repair which will then be glaringly obvious.

thanks but didn't answer the question. Garage did look at it and confirmed the failed items after we investigated. the next question is what else could be route cause. this morning driving to work ( for an other car OEM), with heater swtiched on high - car warmed up and temp guage behaved as normal.) thought maybe thermostate as never changed before. now thinking maybe aux belt.

Don't know. If guage is ok then maybe the fan belt or flush the radiator. Sorry

ignore last statement. temp gauge always still reading high. with or without a/c. (must have just been short drive with a cold block this morning. )
