Hello, I own a 2004 Euphonic edition mk2.5 and I want to drain the coolant and replace it. I use to have a mk3 nc1 and I used FL22, it was great, but I’ve done some research and I don’t think you can use FL22 for the mk2.5 something to do with the block being iron or something like that. Thought I would make a post here just to be safe and if I can’t use FL22 what should I be using instead?
Thank you!
