What would go wrong?

[SOHC]

arrhhh...just took my car into K-xxxx and ask them to do the time belt and waterpump for me, so they just drain my G12 which is a month old and poured some green Castrol coolant in it!!! should I just leave it for a while or flush it again ASAP? What would happen if I don't? coz i don't have a place to work on my car.

Don't take your vw at that place there cheaper for a reason, take it to a vw specialist if you don't want to work on it yourself. It won't hurt the car but change it when you got a free moment, I wouldn't stress about it.

No way would I have anything other than VW coolant. You are asking for trouble.

At least it has coolant in, not just water.

I`d leave it till the next oilchange and sort it then.

Just goes to show, either take everything to the monkies and get them to fit it exactly as you instruct them, or take it to someone who knows the cars.
