Coolant shelf life

[Noesph]

I'm planing on changing the cam belt and water pump on my old 106

In the garage I have a bottle of BASF Glysantin G33 9735.k4 (the stuff PSA uses in there new cars from the factory) info on link

Trouble is it was opened around spring time last year (top was screwed back on the bottle), would all the corrosion inhibitors etc still be ok / as good as a new bottle?

Check whats correct for your car and get the right stuff. There are various different ant freeze products available. To answer your question though, im sure it will be fine.
