V8 Engine Parts
Discovery 1 V8 engine parts for routine servicing and common engine repairs, including spark plugs, air and fuel filters, water pumps, oil pressure switches, coolant temperature senders and auxiliary drive belts.
Start with the engine and the part being replaced, then check the original part number and vehicle setup. Rover V8 components are often shared across different Land Rover models, but airbox type, belt layout, power steering equipment and sender references still need to match the Discovery 1.
