yellowy green antifreeze-what type is it?

[brianw]

I want to get some antifreeze so that my Father in law can have some ready in the boot of his 1.8.
His antifreeze appears to be a yellowy green colour not pink like OAT.
Could anyone suggest what type this is?
Also is it ok to continue using it?
Would rather not drain down, flush and refill if avoidable.
I also remember reading the thread about OAT possibly attacking the gasket sealant so thought it might be wise to keep as is, if I can find the correct coolant to top up with should it become needed.
The car in previous ownership had been serviced at the supplying dealer on all but the very last service which was carried out about 3000 miles ago at a Ford dealership - dont know if that gives any clues.

I believe it's a type made from Superior Monoethlene Glycol base. I wouldn't mix it... I think Toyota sell it. Or Ebay: http://www.ebay.co.uk/itm/5L-COMMA-X...item20c5e4b488

Thanks for that Bill.
I wonder if there is any definitive way to tell whats in it?
As you say I really dont want to mix types. I think I read that especially mixing OAT with some types can cause a reaction.
No sign of any loss at the moment but want him to have some to hand.

The fluoroscein dyed antifreeze (yellow-green) is the classical inorganic (silicate) formula with a two to three year service life. Never mix antifreezes of different colours. It's not due the ethylene glycol (which is the basis of them all), but the inhibitors used.

Thanks TCut very usefull chart.
Looking at it I see three possibles then:

conventional high silicate

conventional low silicate without SCA

conventional fully formulated with SCA

Looking at the compatibility chart though each of the above should only be mixed with its own.

The first two are also shown as meeting Ford Spec and as it was last in at a Ford garage that could be when it changed.
