Fitment Notes

• Always match OEM reference number(s) and vehicle details before ordering. Confirm exact fitment using VIN, engine code, or chassis number if multiple variants exist.
• This is a 3-way lower cooling hose — compare the new hose routing layout, branch positions, and connector diameters to the removed hose before fitting.
• This hose fits 1.6 and 1.8 petrol Astra H / Zafira B applications only (Z16XEP, Z16XER, A16XER, Z18XER, A18XER, A18XEL engine families). It does not fit diesel, turbo petrol, or 2.0-litre variants.

Installation / Use / Maintenance Tips

• Drain the cooling system below the level of the hose before removal.
• Inspect radiator and water pump pipe stubs for corrosion, scoring, or swelling before fitting the new hose.
• Use new hose clamps where the originals show signs of fatigue, corrosion, or deformation.
• Refill with the correct coolant type and concentration per the Opel workshop specification, bleed all air from the system, and run the engine to operating temperature.
• After installation, check all three connections and the full hose length for leaks during and after the first heat cycle.
