300TDI coolant bypass hose replacement

This coolant bypass hose fits Land Rover 300TDI cooling systems in Defender, Discovery 1 and Range Rover Classic models. It replaces Land Rover part number ERR5099 and is identified in the fitment data as a pump-to-body coolant hose.

Replace the hose if the original is swollen, split, hardened, oil-contaminated or leaking. Ageing coolant hoses can look acceptable externally but become soft, distorted or unreliable once disturbed during cooling system work.

Check the hose route and end connections against the vehicle before fitting, especially where previous repairs or engine swaps may have changed the coolant hose layout.

For related cooling system parts, see our Defender cooling parts, Discovery 1 cooling parts and Range Rover Classic cooling parts.

Warranty

All parts sold by Twinwoods 4x4 are covered by a minimum 12 month warranty against manufacturing defects.

Some products and brands may carry a longer warranty period where this is provided by the manufacturer. Where applicable, this will normally be stated on the individual product page.

The warranty covers manufacturing defects only and does not cover failure caused by incorrect fitting, misuse, accidental damage, normal wear and tear, or faults elsewhere on the vehicle.

Warranty claims may require the part to be returned for inspection and testing before any repair, replacement or refund is authorised.

This does not affect your statutory rights.
