Some mechanical difficulties cannot be anticipated. When a part such as an alternator fails, for example, it may be without warning; preventive measures don't apply. But when the alternator light comes on because a worn drive belt has been overlooked, that situation need not have happened. Most highway breakdowns can be avoided through preventive measures done on one’s "home turf."

So before you leave on your vacation trip, find out whether or not your vehicle is up to the task. Use this checklist from the Car Care Council to give it a good "physical." After all, if your vehicle doesn’t enjoy the trip, you probably won’t either.

NOTE: If your plans include towing a trailer or hauling abnormal loads, consider installing overload shock absorbers for a safer, more comfortable ride.

Another useful addition is an auxiliary cooler to protect the automatic transmission under severe driving conditions.

COOLING SYSTEM

Coolant at proper level and clean; pressure cap, thermostat and hoses in good condition. Connections tight.

Check condition and adjustment.

Check fluid, where applicable. Inspect terminals.

As a preventive measure, invest in a diagnostic check of electrical, ignition, fuel and emission control systems. Have needed services, including tune-up, performed.

Check all of the fluids. Change engine oil and filter, transmission fluid and filter, as needed. Lubricate chassis where applicable.

Check steering linkage, shock absorbers and/or struts. Inspect tires, rotate and balance as required. Check wheel alignment if tire wear so indicates.

Inspect brake lining and pads, hydraulic system. Replace worn parts.

Check for holes in muffler and pipes, loose support hangers.

Check operation of wipers and washers. Inspect wiper blade and arm. Replace as needed. Top off washer fluid.

Check all lights, turn signals and flashers.

Start out with a clean car, inside and out. Clean and apply wax or other protective coating to paint and trim surfaces. Clean and repair interior fabrics.
