Coolant capacity?
« on: June 29, 2015, 08:34:31 am »
I'm going to drop the coolant today in order to change the thermostat. Does anyone know what the capacity is? Is it G12 or G13?

Blimey is that all? I have just been looking at VW Vortex and people are stating it's 8 litres, I guess that is with a completely dry system? I was going to get two 5 litre bottles of ready mixed G12 do you think I could just get away with one? I'm going to completely flush the system with the hose.

One 5L will do it unless your going to flush the system.

Cool, I doubt I'll be able to flush all the old coolant out so I'll stick with one 5L  :happy2:

I have VCDS but I don't recall seeing any options to do this on there?

In the throws of doing this now actually... is it an easy enough job to do? I've got an 07 Match FSi and I can't see it ever being done in the service book...

The current stuff in there is pink in colour so I'm guessing its original VW. So I'm looking at some G13? I know it's backward compatible with G11/G12 etc.

So where do I start? Completely cold engine, I read mixed reports about the Mk4/5 having a tap on the back of the radiator that you can access when the car is jacked up? Do you start there  :smiley:
