Hey guys,
I am about to tackle this service myself. I was curious about the coolant flush. How much new coolant do I need and where should I get it?
I plan on doing pollen filter (clairparts), oil filter (clairparts), air filter (clairparts), mobil 1 synthetic oil (costco), and sparkplugs from (autohausaz.com).

Any other advice would be helpful.

Thanks

as for the coolant, I was good with 3 bottles of G12 and I also bought a couple gallons of distilled water. You can buy the G12 from any VW dealership.
