Hi, new member and owner of 2004 Saab 9-3 Aero sedan. Got it last month with 72k miles, SoCal car all its life (no rust) and reasonably well cared for but not by an enthusiast.
I'm starting out with basic maintenance and fluid replacements because there was no actual paperwork on the history other than what I could find on CarFax and the VIN Decoder sites.
I used to own Porsche 944s and have a good amount of the antifreeze coolant Pentosin SF (pink color). I know this was not the factory-specified coolant (Saab/GM), but wondering if anyone on this site could give good guidance on using Pentosin in my 9-3 Aero today. Don't see any particular issues or red flags that would scream "don't do that!" Thanks
