It was intended for the OP.

Green coolant for an iron block/alloy head combo i.e. all the older ohc inline engines.

Don't mix blue colours (this includes green) with reds (including purple) without completely flushing the system* out first.

Unless of course you want a coolant system full of brown tarry sludge that needs acetone or brake cleaner to dissolve...

* and some system cleaners can do more harm than good!

Green? That was G10...doubt if any of that is still around....G11 is blue...G12 purple and not compatible but G12+ is..G13 is in for life...and very good stuff...drain you full system..hose it out..suck it dry with a wet vac...dill it with water..do it all again...back flush the engine, rad and matrix...remove as many pipes as possible...then fill with 50/50 water (de iron if your southern) and G13... Sorted...applies to all engines...WBX won't tolerate water for long...diesels will but eventually will have issues..

SA uses green coolant and our '99 Sharan has used it from new!

-7 degrees in some places last night

Hey Mr/Ms "wbmkk", I hope your motor is OK. Did you sort your coolant out yet?

Mine appears to be using a rust coloured anti freeze, we had temps down to -15 and oft survived.

A weak and old solution may just about prevent freezing but as you have witnessed....it doesn't stop the innards of your engine corroding.
