Going to do a coolant this weekend and the local motor factors only have Red G30 coolant in. Is this ok to use on the PD150. The book does specify G12

Cheers

Nope. G30 looks like a Mono Ethylene Glycol while the VAG G12++ (note the ++ suffix!) is Organic Acid Technology coolant. They don't mix and when added together they form a brown sludge.

I may be wrong though, but the dealers stuff is not too expensive anyway.

Having checked further online, there's much discussion about G30 coolant and whether or not it's suitable. A couple of sites say that G30 is Ethylene Glycol based, while others say it's OAT. Given the grey areas I'd just go with VAG stuff personally.

Ok so ive been onto the Commaoil website looking at these Coolant and Antifreeze

G30 = VW G12/G12+

G40 = VW G12++ for cars from 2005

G48 = VW G11

So would the G40 (G12++) be ok for a 2002 PD150

Found the website who produce the stuff and says OEM requirements

http://www.commaoil.com/productsguide/view/6/350/XSM5L

Plus VW want £36 as this G30 is £17
I thought G12+ was only about £6-8/litre?? so u'll need 3 litres, so around £20?

I've paid £6 in the past from my local VW parts place, and I'm guessing not much more from TPS VW dealers?
