This should be quick and not political (surely)

This is due to (my) ignorance so bear with me

Generally does pink antifreeze go with pink antifreeze and
blue anti-freeze go with blue antifreeze.?

The reason I ask is I have different types in different classics and I know pink and blue must never be introduced.

However .....

If I can see that there is pink antifreeze in my system (and I didn't put it there) could I put quality pink antifreeze and not worry about reactions?
(and - I guess - same Q with blue stuff).

A good example is that I have Jag pink antifreeze in the Lotus (yes I know this is a stag forum but the question is quite general) - anyway the pink stuff is part number JLM209723 and I can't find the blummin stuff anywhere so in this example would a quality pink be good enough?

I've also been told (can't remember who by) that Stags prefer blue - is that generally accepted?

Thanks.

P.S. See how I skirted rounded the 'waterless' stuff ? - I did a pre-search on that and boy am I glad I'm not mentioning that! Sort of.

If it looks pinky or red you can only put in pink

Green or blue, you can add blue. If it was me though and it had green drain it down and then refil with blue.

You cant mix pink and blue and it will clog things up

Either way, get the concentrated stuff and not the Halfrauds ready mixed

If I were you I would drain it out flush it and start afresh for the time and the money it costs, peace of mind

Thats good advice by Graham

great answers - thanks for that, seems i was right (amazing)

re- drain and flush and fill.
i can do that on the stag, still have to work it out on the 'spree
