Dex Cool Issues

For me it is an easy choice. At $24.00 a Gal and no compatibility or gel issues....go with what Porsche recommends.

Yes, I will be flushing the system and THANKS!! JFP for the vacuum recommendation. At $100 from Amazon, it is just another tool in my Porsche tool collection (which is getting bigger and bigger.....).

I am buying a reman waterpump with the metal impeller and the 160 degree Tstat. If I am going to do it, I want to do it right!

Actually, the Uview tool, with all the adaptors that comes with it, will work on literally anything with a cooling system......

Why the 160 t'stat?
the ECM needs to see 180 to run the engine efficiently

I bought a metal impeller water pump awhile ago for another vehicle and it weeped since day one. On that vehicle it was a 3.5 hour job to change it out again. I got a refund and went with a factory reman for the replacement.
Plastic impellers are not a bad word. If the metal was superior I would think all the luxury car manufacturers would use metal. The difference in cost is minuscule

Nonsense........We have them in about 15 cars, all of them pass emissions testing and, in fact, dyno testing has shown slight HP and torque increases due to improved volumetric efficiencies...................the DME has more than enough range to adjust to changing to 160F stat.................
