Matching Radiator Hose: Kevlar Top Radiator Hose (BN1-BN2).

Coolant & Cooling Care:

• Millers Extra Cool - 250ml - coolant enhancer and corrosion inhibitor.
• Alpine Blue Antifreeze Concentrate - 1 litre - traditional IAT antifreeze for classic cooling systems.
• Alpine Blue Antifreeze Concentrate - 5 litres - the same antifreeze in a larger container.

Alpine Blue must be diluted before use. Millers Extra Cool is a coolant enhancer, not an antifreeze.

Fitting notes and limitations

• Inspect lower radiator outlet and engine connection for corrosion or pitting before fitting.
• Ensure the hose is fully seated, then tighten clips evenly.
• Recheck clip tension after the first full heat cycle.
