Why choose the clear expansion tank?
The original black expansion tank makes it harder to see the coolant level at a glance. This clear replacement tank lets you check the level more easily, making it the better choice where the clear version is available at the same price.
The tank is supplied without a pressure cap. If you need a new cap at the same time, use the NTC7161 / NTC7161G expansion bottle cap for Defender, Discovery 1 and Range Rover Classic.
Prefer the original black tank? Leave a note in the order comments and we can order in the black version instead. The clear and black versions are the same price.

Buy with confidence: all new parts sold by Twinwoods 4x4 include at least 12 months manufacturer warranty against defects in materials and workmanship under normal use.
Some products and brands may include a longer warranty period where this is provided by the manufacturer. Where applicable, this will normally be stated on the individual product page or covered by the manufacturer’s own warranty terms.
Warranty cover applies to manufacturing defects. It does not cover misuse, incorrect fitting, competition use unless stated, contamination, modification, damage during installation, normal wear and tear, or failure caused by an unrelated vehicle fault. For certain components, proof of professional fitment may be required.
Warranty claims may require the part to be returned for inspection and/or supplier testing before the claim is accepted. Any advance replacement is discretionary.
Warranty remedies relate to the part itself, meaning repair or replacement, or refund if those are not possible. Warranty does not cover labour, removal or refitting, diagnostics, consumables, travel or other incidental costs.
This warranty is in addition to your legal rights and does not reduce those rights.
