Frequently asked questions

What is the timing chain guide nut used for?
The timing chain guide nut is a special fastener that secures the lower primary timing chain guide on 2.0L Ingenium engines. This Genuine Land Rover nut fits Ingenium diesel, petrol and PHEV variants used in models like the New Defender, Discovery 5, Discovery Sport and Evoque L551.
How many timing chain guide nuts are needed?
The quantity of timing chain guide nuts depends on the job, as each guide is held by its own fastener. Check the number your timing chain guide requires during a timing repair, as this part is typically sold individually.
Can the timing chain guide nut be reused?
The timing chain guide nut is a torque-critical fastener and is typically replaced whenever timing chain work is carried out. Reusing a stretched or previously torqued nut risks losing clamp load, so fitting a new Genuine nut during the repair is the safer choice.
