    1991 Porsche 944 S2
  1. Hi, I have been reading this forum for a while but this is my first post. I have tried to find a post referring to this but I had no luck. I have a number of questions. First, does anyone know if VW G12 plus coolant is suitable (as 50:50 mix) for a 944S2? As far as I can tell, I need to use phosphate free coolant, but this does not state whether or not it is phosphate free. If I need to get another type, that's no problem, I just had some of the G12 plus in the shed anyway. Second, I need to flush out and re-fill the coolant in the system but am not sure where to start! I have asked the local mechanics, but none of them want to touch the car as they have never worked on a Porsche before and I an no where near the only Porsche dealers in the country, so I cannot get to them and they refuse to recommend any type of coolant other than the Porsche approved type! So any advice, or a standard procedure for flushing and re-filling would be very much appreciated. Finally, I before I flush out everything etc, can I add the above coolant (if it is suitable anyway) to what is there already? I know this may not help but it is a light blue colour, but my antifreeze tester says it is almost water now! Would it be better to top up with water instead? Sorry for the long post and thanks for any help! B
