Antifreeze, which one?
Zetec engine, which uses OAT antifreeze normally.
However, the car is old and and has copper/brass heater etc, plus I have used copper pipes in the cooling system.
Seems the OAT stuff is not a good idea with brass/copper and indeed anything with solder??
Should I use the old blue antifreeze, or will that cause issues with the engine??
Any pointers, apart from use the OAT and cross fingers (tempting!)

I know one that still makes coolant suitable for their old engines with copper rad's as well as there new stuff that's a mix of iron and
alloy... John Deere !
their current stuff is called cool-guard II - here's the specs:

should be easy enough to get too - they've got dealers for the tractors or lawnmowers all over the country

I'd put OAT in.
I've got copper pipes between engine and rad with soldered joints. No issues in 6 years. I use 33% OAT with de-ionised water.
I looked into waterless coolant this year and weighed up the pro's/con's and it seemed good but the price and fact you can't mix it
should you have an issue and need to top up tipped the balance back to water/AF.

OAT is fine as is decent quality blue/green, I use Granville Zerocol Red OAT because I bought 5ltr of concentrate at good price during the summer.
Just take care to check if you are buying concentrate or 50 percent premix coolant. Premixed is fine if you live in a hard water area otherwise buy
concentrate as is better value for money.
A solution of 50 % is ideal but anywhere between 30 and 60% is fine.
Anything over 25% is enough for frost protection in the UK climate, but higher concentrations give better corrosion protection and guard against the
solution getting diluted in service.
Over about 60 precent solution the frost protection slowly falls off.

I live down sarf, rarely gets very cold, so a 10% solution would stop damage. It is always the anti corrosion bit I am worried about.
I have red stuff here, std OAT (I though oat was red, hoat purple, and the old glycol stuff blue or green??) from vauxhall, so will give it a shot. I
guess if it is a problem, I have spare heater matrix's and a bit of copper could be replaced with rubber, though not as neat/tidy.
Cheers all for the thoughts...

10% will not give enough corrosion protection and you have to allow for dilution in service.
Copper has no problems with OAT coolant.
Coolant can be any colour Japanese tradditinal coolant was red. I recent years green blue has become standard for old style coolant and
red/pink/purple for OAT or HOAT.
