In addition, coolant in the oil provides an extreme lack of lubrication properties, furthering the destruction of internal engine components. Since 2018, in turn, the G12evo is again considered the successor to the G13. In 2012, the G13 standard replaced the first G12 coolants. How long have you been driving the car like this? Extreme engine heat can destroy engine components and warp the cylinder head. Only G12+ and G12++ coolants are recommended for the Golf 5.

Im not recomending this for you, but saying its a possibility.Īnother thing is what mileage are you at? because i think if you havent had your timing chains done ( again im not sure, but i think there chains on VR6's) than you need to have them replaced before they go bad.

Im not sure about anything on a VR6 but it could be one of two things that iv had problems with coolant. G13 is the latest VW specified coolant but any old G12 is fine.
