Millers Alpine Blue Concentrate is a traditional Monoethylene Glycol (MEG) antifreeze formulated with Inorganic Acid Technology (IAT) — the correct coolant chemistry for classic engines. Ideal for Austin Healeys and other classic and vintage vehicles using copper, brass, and soldered radiators, it provides dependable frost and corrosion protection without attacking older metals or seals.
Suitable for all Austin Healey models (BN1–BJ8 and Sprite/Midget) using classic copper/brass radiators or heater cores. Also compatible with other British classics requiring an IAT ethylene glycol coolant.
Not suitable for: vehicles using modern aluminium radiators designed for OAT or hybrid antifreeze formulations.
Drain the existing coolant and flush the system. Mix Alpine Blue Concentrate with deionised or distilled water before filling (do not use tap water). After filling, run the engine until warm to circulate and expel air pockets. Dispose of old coolant responsibly.
Modern OAT antifreezes are unsuitable for classic radiators — they can attack solder and brass. Millers Alpine Blue provides period-correct chemistry with proven corrosion inhibitors, giving classic Healeys modern reliability without compromising originality.
Yes — it’s specifically designed for classic radiators using copper, brass, and solder joints, unlike modern OAT antifreeze which can cause corrosion.
Replace every 2 years or sooner if the coolant appears cloudy or rusty. Long-term protection depends on correct concentration and clean mixing water.
No — do not mix with OAT or hybrid types. Always flush the system before switching formulations.
Use deionised or distilled water. Tap water introduces minerals that reduce corrosion protection and cooling efficiency.
This is a concentrate — mix to your required protection level before filling.
