Have a Mk4 Golf. Dealers and mechanics have said that you can only use the VW orange coolant. Is this true or only for warranty issues? Its so expensive even compared to a good "normal" green coolant.
Thanks.

I used to work for a VW dealer...we had an apprentice change the coolant on a T4 and she put in Mitsubishi coolant.After bleeding it up etc she took it for a drive and the engine overheated and siezed.The coolant had reacted and turned into a jelly type of stuff,consequently causing the motor to overheat and die. The dealer had to buy a new motor as VW wouldn't cover the engine with the wrong coolant.Moral??? If the car is under warranty use the specified coolant. It's used for a reason.If you decide to skimp out and buy cheaper stuff,THOROUGHLY flush the system before trying something different and chang it more often.The VW stuff is good. I'm glad I wasn't at work that day!!!

Ive heard that later Golf engines generate a fair bit more heat during operation than most other watercooled motors... maybe that is where the special coolant comes in? dunno.... just food for thought... 🙂

If you have the Lilac G12+ coolant already in it, then I'd stick with that....I've seen coolants mixed that have gone all gluggy. You should only have to change the coolant once every 2 years, so the cost isnt really that much to use the proper VW coolant.
