Now is the time for preventative maintenance for your vehicle!

Our goal at Twin Lakes Auto Service is to keep you safe on the road. We can handle all engine repairs and auto service needs you may have whether related to safety or performance. Is it time for an oil change or transmission tune up? Read on for tips and check list to keep your vehicle running like a champ.

Know your vehicles’ service schedule

Follow the manufacturer’s recommended service schedules, these can be found in your owner’s manual. There are usually two schedules listed: normal and severe.

Engine Performance

Have engine drivability problems (hard starts, rough idling, stalling, diminished power, etc.) evaluated and corrected by one of our skilled Techs. Because cold weather will make existing problems worse, make certain that you stay on top of any signs of engine troubles. Be sure to replace dirty air filters, fuel, PCV, etc.


Change your oil and oil filter as specified in your manual (usually every 3,000 miles or so) if your driving is mostly stop-and-go or consists of frequent short trips. Regular oil changes are one of the least expensive but also one of the most important preventative measures you can take for your vehicles’ maintenance.

Cooling System

The cooling system should be flushed and refilled as recommended. The level, condition, and concentration of the coolant should be checked periodically. (A 50/50 mix of anti-freeze and water is usually recommended.) If you’re doing your own work, allow the radiator to cool down completely before removing the cap. (Newer vehicles have coolant reservoirs.) The tightness and condition of drive belts, clamps, and hoses should be checked by a certified auto technician.


Are you prepared for the Northern Arizona winters? The heater and defroster must be in good working condition for passenger comfort and driver visibility.

Windshield Wipers

Replace old blades. If your climate is harsh, purchase rubber-clad (winter) blades to fight ice build-up. Stock up on windshield washer solvent you’ll be surprised how much you use.


The only accurate way to detect a weak battery is with professional equipment. But do-it-yourselfers can do routine maintenance. Scrape away corrosion from posts and cable connections; clean all surfaces; re-tighten all connections. If battery caps are removable, check fluid level monthly.


Inspect all lights and bulbs; replace burned out bulbs; periodically clean road grime from all lenses with a moistened cloth or towel.


Examine tires for remaining tread life, uneven wearing, and cupping; check the sidewalls for cuts and nicks. Check tire pressure once a month. Let the tires “cool down” before checking the pressure. Rotate as recommended.


Carry gloves, boots, blankets, flares, a small shovel, sand or kitty litter, tire chains, a flashlight, and a cell phone. Put a few “high-energy” snacks in your glove box.
