Expansion tank / coolant colour
« on: 13 November 2017, 15:08 »
I've only had my car 6 weeks, I just went to top up the washer fluid and noticed the expansion tank, in all my other golfs you could clearly see the usual orange coolant colour through the tank, however mine looks muddy brown, not good!

thoughts?

That does look a bit manky, have you taken the cap off and looked inside? Any gunge visible under the oil filler cap or dip stick?

Thanks for your reply.  Underneath oil filler is clean, as is dip stick.

I looked in expansion tank, there is some small spots in the bottom, but it's pretty clear, but not orange!

Can't see the pictures (in work) but if the water looks mucky, it could be contaminated with oil (head gasket?).

Might be worth checking the oil filler etc. for mayo buildup too?

Note to self, don't speed read the thread  :wink:

Might be worth getting the coolant changed out and see if it comes back?

VW G13 coolant is pink not orange AFAIK. It looks ok to me but if there is sediment in there also you might have a problem.

So after much back and forth with my local main dealer and the supplying dealer, I ended up taking it back to the supplying dealer, as the local main dealer were basically saying it is not covered under Das Welt and "who was going to pay for it".  Supplying dealer is 100 mile round trip, and they said they would speak to my local main dealer, and confirm it would be covered by them, but the more I talked to them, the more it sounded like a potential for a f*ck up.  So I did a deal that if I bring it back to them, they would return the car to me with full tank of fuel, as they wanted the car for a few days.

So they had the car back and flushed the coolant system, replaced coolant bottle with a brand new one and refilled with new coolant.  They said they couldn't find a fault. Someone suggested it might of been the previous owner topping up with blue coolant and not pink, and them mixing together, who knows?  Still odd whatever it was, wasn't spotted on the bulls!t Das Welt check. I am going to keep an eye on it and will report back if it reappears.

So the coolant hasn't changed colour since having the work done (see above), but it has lost a bit, from looking at other threads, I understand this is common in Mk7s for them to use coolant.

I was looking at buying some G13 to top it up and what is now in my car looks more pink, and I understand it should be G13 which is purple coloured.

What do you guys think?
