Car batteries lose power as the temperature drops. Belts and hoses are less flexible, tires lose air pressure, and engine oil thickens. Winter can be hard on vehicles.

“Marginally operating systems can fail outright in extreme weather,”Martin Lawson is the National Institute for Automotive Service Excellence’s editorial director.

These tips are from ASE to help drivers prepare for winter’s most difficult conditions.

Cooling System. To prevent engine damage due to freezing or overheating, it is important that the coolant be tested for its level, condition and concentration. You should also inspect the condition and tightness of all drive belts, clamps, and hoses.

Oil. Your manual will tell you how to change your oil and filter. If you live in very cold regions, it may be necessary for your vehicle to use winter-grade oil. It has a lower viscosity, makes it more easy to start, and is therefore less expensive.

Engine Performance. Engine performance. Get problems like rough idling, stalling, hard starts and stalling fixed quickly, as cold weather can make existing problems worse.

Windshield Wipers Replace worn or streaking blades. Rubber-clad blades (winter) are recommended for winters that are particularly harsh. You should always have extra windshield-washer solvent, and an ice-scraper.

Battery. You can’t remember when you purchased a new battery. A weaker one will most likely die in winter. To be certain, have the charge checked by a qualified repair shop.

Tires. In winter snow and slush, balancing tires are not recommended. You can either replace them with all-season or snow tires if you live in heavy snow. All tires should be checked, including the spare.

Emergencies. Keep gloves, boots and blankets with you in an emergency.

Safety. Before you drive, remove all snow and other ice. Clear snow from your vehicle’s headlights and taillights to increase visibility.

ASE was created in 1972 to improve quality of car service and repair. ASE-certified technicians sport blue and ASE shoulder insignia, and their employers carry the blue and ASE sign. They are found in all kinds of repair facilities, including franchises and independent garages. Visit www.ase.comFind out more tips for seasonal car care.
