Coolant for the VW Golf 4
The Golf 4 (IV) replaced the Golf 3 (III) in 1997 and was in turn replaced by the Golf 5 (V) in 2006. While the Golf 4 was the latest series to come off the line, VW used G12+ coolant as the latest standard of in-house coolants. If you take a look at the original Golf 4 vehicle manual, you will always find the G12+ coolant as a recommendation. In the lower part of this page we have provided you with a list of which coolant and total quantity is required.
The special feature of the G12+ coolant is that it is the successor to the VW G11 coolant and for the first time uses organic acids for corrosion protection. The successors of the VW G12+, VW G12++, VW G13 and VW G12evo also do without the inorganic acids of the G11.
You can read more about this in our G12 coolant article.
Replacement of the G12+ standard
Already with the successor, the Golf 5, a further developed standard was recommended with the G12++, which in turn was replaced by the G13 coolant. Since 2018, VW presented the latest standard with the G12evo. Despite these further developments, the G12+, G12++, G13 and G12evo coolants are mixable.
G12evo for your Golf 4
Due to the advancement of the standards, VW stopped the production of the outdated ones and currently only produces the G12evo coolant. Since this is backwards compatible as well as miscible with the previous standards, only the latest G12evo is available for you to choose from when purchasing an original VW coolant.
