This guide will show you how to renew your old existing Bonnet Pin and Lock. Please read this guide through at least once before fitting.
Step 1. (Optional) Preparation prior to fitting
Before you start removing your old parts you may want to consider preventing your new parts from corroding like the existing ones. You could smear a protective oil or grease over the exposed metal and rub it over or you could like myself spray paint the metal parts.

Step 2. Draw around the Bonnet Pin
Open bonnet and secure with the bonnet stay. It is important that you refit your new bonnet pin in the exact same position as the old one, so carefully with a pencil or dry marker, draw around the bonnet pin.

Step 3. Removing Bonnet Pin
Using a ratchet and a 10mm socket, slowly start to unscrew the two bolts holding the bonnet pin to the bonnet. If the bolts are rusty try to use some WD40 to help penetrate the rust.

Step 4. Removing Air Intake Pipe
Carefully remove the air intake pipe over the radiator using the 10mm socket on the three bolts highlighted below.

Step 5. Unhooking the Bonnet Release Cable & Removing Lock Once the air intake pipe has been removed, you should now be able to see between the slam panel and the radiator. Carefully looking between and you’ll see the bonnet release cable. To detach the cable simple put a flat headed screwdriver into the position indicated by the red dot and carefully prise the cable out of the clip.
