The OP should just flush and refill with 40-50% antifreeze.
Takes no time, and is well worth doing.


I wish I had a 50 quid for ever motorist who has thought that, only to find
they have problems ! What you say was true some years back but not now, many
engines have coolant systems that are far from simple to refill unless one
knows how to do it.
