19 Ground Is Good
Here is an example of an engine ground on an early '60s Pontiac. Get to know where the major ground circuits are on your Pontiac (engine block, lights, and so on). Every few years, take them apart and clean the connections. An electrical circuit is only as good as the ground path. Some dielectric grease will help keep the newly cleaned ground performing perfectly under all conditions. Remember that electricity is lazy and will take the path of least resistance. Often a poor ground will be hard to diagnose since you cannot anticipate how the circuit may respond.
20 Relative Motion
Turning the steering wheel while your Pontiac is stationary puts extreme pressure on the power steering unit and hoses and causes excessive wear on the frontend parts. Get into the habit of allowing the Pontiac to roll ever so slightly while turning the steering wheel, even when parallel parking. The power steering pump and frontend will thank you.
21 Bonus Tip
Take It Off
We know that washing and waxing your Pontiac not only makes it look great, but helps make it last. A quality wax protects the paint and bodywork, while repelling dirt that can grind into the finish. Don't forget the door jams, trunk, fenderwells, undercarriage, and underhood areas.
Along with typical cleaning, you should also consider removing your Pontiac's trim and bolt-on spoilers each year to clean underneath them. On vintage Pontiacs, debris and dirt gets behind the front and rear window moldings and rots out the window channels. Remove the moldings using a tool designed for the job and clean out those areas. Wheelwell moldings also trap dirt and debris, and should be removed at least once per season to clean the area between them and the wheelwell lip. Any Pontiac with spoilers and/or ground effects can trap dirt and moisture beneath them as well.
