Pre-MOT Inspection Checklist for Vauxhall Monaro Owners

These checks follow this Vauxhall Monaro's own most-recorded failure strings, starting with what a tester is most likely to flag on a Vauxhall Monaro.

• the suspension joints — “linkage ball joint dust cover ball joint dust cover severely deteriorated”

  With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.

• the windscreen — “windscreen damaged”

  Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.

• the battery — “battery(ies) insecure”

  Check the battery is secure and its terminals are clean and tight — a loose battery is a fail on its own, and a weak one shows up as slow cranking on a cold morning.
