Adding coolant to your 99 vw golf gti?

ONLY GET VW COOLANT or be dumb and put cheap stuff in and pay for it later. NEVER put green coolant in. Will destroy all coolant parts. It will rot them. Happened to me. I had to replace it all.

as with most cars you should almost always follow vehicle manufactures recommendations. I'm lucky, I have a 20 years plus VW dealer tech in the family and he warned me of this when I bought my 1998 2.0 GTI. The same is true when adding Power Steering fluid. In high school auto shop I was taught that regular ATF fluid was acceptable to use in place of power steering fluid. not the case any longer.
