Owner reviews for antifreeze

Drain/refill every two years for me, Pentosin coolant only!

I personally use Pentosin SF for GM cars,it's not the cheapest,but it is one of the best. Made in Germany. Similar to Dex-cool but pink,no problems.

I’ve used that stuff, absolutely no issues.

I run it and haven't had any problems, just topped it off and kept rolling.

CRP the USA distributor for Pentosin; discusses, service intervals with the various long life VW coolants (g12, 13, etc): in their line Pentofrost SF, E, etc @ 14:00: Pentosin - Antifreeze Looks like Pentofrost E; the latest G13 equivalent is recommended for your car with crp's application guide; mixed @ 50/50 with deionized water

If you are going to use Prestone brand, then you'd want Violet color.

I personally just use pentosin. They're only about $13 for 1.5 liters ( here ) and makes 3 liters. I keep a few bottles and some distilled water in my garage just in case.

Gear Hell no! Don't use that generic auto parts store crap. Pentosin, VW/AUDI only. Unless you don't like your car!

The Peak coolant that is the correct color for your year, i.e. pink for the MkIV, is fine. I have been using it for several years with no problems.

When I bought my Jetta it was filled with Prestone. One time the fan switch crapped out on me so while replacing it I did a coolant flush and decided to use G12. About 2 weeks later the car started overheating like mad.
