Check Defender 300TDI fitment before ordering

The 300TDI engine shares many service, timing and internal components across Defender, Discovery 1 and Range Rover Classic. Surrounding parts can still differ by vehicle and production detail, so use the product title, original part number and fitment notes together.

Defender-specific parts
Air filters, hoses and surrounding installation parts may differ from Discovery 1 and Range Rover Classic fitment.
Early and later belts
Auxiliary belts and related drive components can have early or later fitment differences.
Gasket identification
Head gaskets and other sealing parts may require the thickness, hole count, position or original reference to be checked.
Kit contents
Check exactly which filters, bearings, belts, gaskets, washers, bolts or seals are included.
