Hi,
I recently had my Polo serviced and they found a coolant leak at the thermostat. Warranty had just run out but I am getting VW to do a 'goodwill' repair. They said that they are going to have to replace the pump or something along these lines and will do it for free, however, I will have to...

hey fellas. The other day I bought about 10lts of distilled water and a few bottles of G13 to flush out the G12

I got under the car hoping to locate a tap or a bottom hose but I was unable to find somewhere to drain out the coolant

Ive done this many times on other VW's...

I bought G13 coolant today from my local VW parts dept.They said they had not stocked G12 for five years and that G12 and G13 were ok to mix...If this is so what is the difference and why the need to call it 13...
Is this correct or do you have to do a complete flush?
Thanks to any inf...

Afternoon

So it seems my coolant flush last week wasn't as successful as I thought so I went out and grabbed some G13 and started again due to green discolouration in the coolant. (im guessing pockets of the prior fluid weren't G13 and were stuck somewhere)

I opened the drain...
