Hi
Sorry for all the questions but the car I’m buying had it’s water pump and thermostat replaced recently.
I’ve seen on the invoice the garage refilled with g40 antifreeze that I believe is g12++.
I think Vw recommend their latest version of antifreeze that’s G13 since 2012.
With some issues with the heater matrix getting clogged do you think I should replace with G13 ?
Any advice would be appreciated.
Thanks
