thanks for the replies guys.
yeah I'm thinking through some of the same rationale.
Prestone MAX definitely is sounding the most appealing.
Going to porsche will be expensive, and its a different formulation anyway from what came in the 986 era.
other suggestions in my research have seen:
HavolineŽ DEX-COOLŽ Extended Life Anti-Freeze/Coolant
Chevron DEX-COOLŽ Extended Life Antifreeze/Coolant
G40 Zerex
VW/Audi OEM G13 Coolant G013A8J1G
main point or takaway I've seen fairly constant is that it should be phosphate free.
also a flush is a must since don't even know what is in there.
so far the only stuff i can find easily locally are the VW/Audi stuff and Dexcool.
if I'm going the flush and don't have the vaccum pump to suck it all out, as long as I'm pullnig the drain plug and main hoses would it be enough to lift the front of the car higher to fully drain the rads?
