This hose connects the coolant expansion tank to the engine cooling circuit, allowing coolant to flow in and out of the reservoir as system pressure varies with temperature. This variant is specified for vehicles without an engine oil cooler; a different hose is required when an oil cooler is fitted. Compatible with 2.25-litre petrol, 2.5-litre petrol, and 2.5-litre naturally-aspirated diesel engine variants.

Frequently asked questions

What does the NRC9726 expansion hose do?

The NRC9726 coolant expansion hose connects the cooling circuit to the expansion tank on the Land Rover Defender, letting coolant flow in and out of the reservoir as pressure changes with temperature. This variant is for vehicles without an engine oil cooler.

How do I know if I need the without-oil-cooler version?

This hose is for Defenders not fitted with an engine oil cooler; a different hose routing is used when an oil cooler is present. Check whether your engine has a cooler before ordering. It's specified for the 2.5-litre 4-cylinder and V8 petrol Defender.

Why do coolant expansion hoses fail on the Defender?

Coolant expansion hoses typically fail through perished, cracked, or swollen rubber after years of heat cycling on the Defender. A failing hose can weep coolant or collapse, causing overheating or pressure loss. Replacing an aged hose restores a sealed, reliable cooling circuit.
