Anti-Freeze
Hi there,
Looking for an anti-freeze for my 1984 metro 998cc and saw Halfords do a blue one that says it is IAT NOT OAT, so would this be ok for this classic
engine? Im just checking because I read that RED OAT A/F kills classic engines.
Thank you

don't know about your engine - but this stuff is safe for just about anything:

Unless the coolant type has been changed it is the correct coolant.
And don't believe everything you read on the internet especially in one make forums,

IAT will simply coat everything in the cooling system with silicates, this coating rate increases as the inhibitors become exhausted.
Therefore, you need to change the stuff frequently (1-2 years) to keep it all clean. Some say that the particulates abrade water pump seals....
I've never experienced this. Thing is, the IAT blue stuff is what I use in all my engines, but then it is changed frequently - voluntarily or
not. I could use OAT in the all-alloy bike engines, but I don't, I certainly can't use it in the old LR since the cooling system is rich
in copper and brass. IAT is what I'd use in your fine automobile.
In my mind (warped with years of cynicism and mistrust), OAT is there for reasons of longevity, to save the dealers money and time. It sits in the
cooling system until the car is well past it's lifetime expectancy (i.e. warranty period), after which no one cares, you've bought the new
shiny appliance after that.

I agree with Mr Mayhem.
