Hi,

I just ordered new dryer for my S80 1999 (165 K KM) My questions is
While Uninstalling or installing new one, does It get AC Freon out or I just simply replace dryer without put the freon out.

2ndly,
I am about to change the Fuel Filter and I would like to add some power full fuel injector to clean the system. Which is better, do I add cleaner after installing new filter or before ?

Thanks for your reading
