YELLOW coolant? G12+ compatible?

[Andy T 0]

My VR is filled with a yellowish coolant (colour of piss actually :? :lol: )

 

I recently replaced a few coolant senders/sensors and topped up with about 3 litres of G12+ mix, question is, is it going to be compatible, and what is the yellow stuff??

 

Should I be doing a ful flush & refill?

I think g12 will mix with all. If in doubt change it, probably better for it anyway.

G12+ will mix with anything.

So not 100% on whether you can get away with the yellow stuff in there....
