Pre-MOT Inspection Checklist for General Motors Cadillac Owners
These checks follow this General Motors Cadillac's own most-recorded failure strings, starting with what a tester is most likely to flag on a General Motors Cadillac.
-
the lights — “registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
the coil springs — “coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
-
the suspension joints — “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.
Derived from the DVSA failure strings testers recorded for the General Motors Cadillac. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
