Did it a two years ago. Ended up phoning prestone as labeling unclear on additives and believe there are two you don't want for the 4-tec (silicate and borate?), a person answered and the bottle I had in hand (in the store was good).
Cannot recall the specifics but followed the manual and was straightforward. Did flush it with a fill, run in lake, before fill with coolant (and distilled water mixture IIRC). Believe the main thing is to check levels after a brief ride (and monitor temps). Recall that having a second person helped - think it was one person filling and other person sealing system when fresh coolant started to pour out.
