GENERAL MAINTENANCE

It's Time for the 21st Century Tune-up

Times are changing...cars are changing. One of the biggest changes in today's automotive industry is the perception of a "tune-up." Ask 10 vehicle owners their definition of a tune-up and chances are there'll be 10 different answers. The classic "tune-up" was once the heart of the automotive business and contrary to some beliefs; today's modern vehicles still need tune-ups to keep them performing at the most efficient levels.

The tune-up was historically associated with the routine replacement of key ignition system parts like spark plugs and ignition points, along with some basic adjustments to help "tune" the engine. Mounting pressure for increased fuel economy and lower emissions drove the car manufacturers to adopt electronics and to do away with ignition points in the '70s, along with the carburetor in the middle '80s. This eliminated the need for the replacement and adjustment of a growing number of ignition and fuel system parts.

As the pace of technology quickened, the procedures required to perform a traditional tune-up changed dramatically. Highly sophisticated ignition and fuel systems are now the norm, using one or more onboard computers to control critical engine and transmission management functions. Things that were once handled mechanically are now controlled electronically through the widespread use of onboard computer technology.

Because vehicles have changed so much over the years, the Car Care Council has introduced the 21st Century Tune-up. This program is designed to help re-define and educate motorists as to what a tune-up should consist of on today's modern vehicles.

"There is a misconception that today's modern vehicles don't need tune-ups because they never break down, but that simply is not true," said Rich White, executive director of the Car Care Council. "If you're at work and your computer goes down, you can't get any more work done. It's the same with your vehicle. If the vehicle isn't being properly maintained, you're not going to get where you want to go."

As part of the 21st Century Tune-up on today's modern vehicles, the following systems should be inspected:

  • Battery, charging and starting
  • Engine mechanical
  • Powertrain control (including onboard diagnostic checks)
  • Fuel
  • Ignition
  • Emissions

Vehicle owners ask for tune-ups for a variety of reasons, including improving performance, maintaining reliability, planning a vacation, preparing for winter/summer or because they're giving the car to a friend or family member.

To help ensure good performance, fuel economy and emissions, the Car Care Council also recommends that motorists take the time necessary to become familiar with their vehicle from every aspect. Study the owner's manual to become thoroughly acquainted with the operation of all systems. Pay special attention to the indicator lights and instruments.

Getting Your Vehicle Ready for Winter

Mechanical failure—an inconvenience anytime it occurs--can be deadly in the winter. Preventive maintenance is a must. Besides, a well-maintained vehicle is more enjoyable to drive, lasts longer, and could command a higher resale price.

Some of the following tips can be performed by any do-it-yourselfer; others require the skilled hands of a professional auto technician.

  • Engine Performance - Get engine drivability problems (hard starts, rough idling, stalling, diminished power, etc.) corrected at a good repair shop. Cold weather makes existing problems worse. Replace dirty filters-air, fuel, etc.
  • Fuel - Put a bottle of fuel de-icer in your tank once a month to help keep moisture from freezing in the fuel line. Note that a full gas tank helps keep moisture from forming.
  • Oil - Change your oil and oil filter as specified in your manual—more often (every 3,000 miles) if your driving is mostly stop-and-go or consists of frequent short trips.
  • Cooling Systems - The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of the coolant should be checked periodically. (A 50/50 mix of anti-freeze and water is usually recommended.) DIYers, never remove the radiator cap until the engine has thoroughly cooled! The tightness and condition of drive belts, clamps, and hoses should be checked by a pro.
  • 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. Carry an ice-scraper.
  • Heater/Defroster - The heater and defroster must be in good working condition for passenger comfort and driver visibility. Newer models have a cabin air filter that should be replaced periodically. Check your owner's manual for the location and replacement interval.
  • Battery - The only accurate way to detect a weak battery is with professional equipment. Routine care: Scrape away corrosion from posts and cable connections; clean all surfaces; re-tighten all connections. If battery caps are removable, check fluid level monthly. Avoid contact with corrosive deposits and battery acid. Wear eye protection and rubber gloves.
  • Lights - Inspect all lights and bulbs; replace burned out bulbs; periodically clean road grime from all lenses. To prevent scratching, never use a dry rag.
  • Exhaust System - Your vehicle should be placed on a lift and the exhaust system examined for leaks. The trunk and floor boards should be inspected for small holes. Exhaust fumes can be deadly.
  • Tires - Worn tires will be of little use in winter weather. Examine tires for remaining tread life, uneven wearing, and cupping; check the sidewalls for cuts and nicks. Check tire pressures once a month. Check the tires when they are cold, before driving for any distance. Rotate as recommended. Don't forget your spare, and be sure the jack is in good condition.
  • Carry emergency gear: gloves, boots, blankets, flares, a small shovel, sand or kitty litter, tire chains, and a flash light. Put a few "high-energy" snacks in your glove box.

Getting Your Vehicle Ready For Summer

Summer's heat, dust, and stop-and-go traffic, will take their toll on your vehicle. Add the effects of last winter, and you could be poised for a breakdown. You can lessen the odds of mechanical failure through periodic maintenance. . . Your vehicle should last longer and command a higher resale price, too!

Some of the following tips are easy to do; others require a skilled auto technician.

  • Air Conditioning - A marginally operating system will fail in hot weather. Have the system examined by a qualified technician. Newer models have cabin air filters that clean the air entering the heating and air conditioning system. Check your owner's manual for location and replacement interval.
  • Cooling System - The greatest cause of summer breakdowns is overheating. The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of the coolant should be checked periodically. (A 50/50 mix of anti-freeze and water is usually recommended.) DIYers, never remove the radiator cap until the engine has thoroughly cooled! The tightness and condition of drive belts, clamps, and hoses should be checked by a pro.
  • Oil - Change your oil and oil filter as specified in your manual-more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage, or tow a trailer.
  • Engine Performance - Replace other filters (air, fuel, PCV, etc.) as recommended-more often in dusty conditions. Get engine drivability problems (hard starts, rough idling, stalling, diminished power, etc.) corrected at a good shop.
  • Windshield Wipers - A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.
  • Lights - Inspect all lights and bulbs; replace burned out bulbs; periodically clean dirt and insects from all lenses. To prevent scratching, never use a dry rag.
  • Tires - Have your tires rotated about every 5,000 miles. Check tire pressures once a month; check them while they're cold before driving for any distance. Don't forget to check your spare as well and be sure the jack is in good condition. Examine tires for tread life, uneven wearing, and cupping; check the sidewalls for cuts and nicks. An alignment is warranted if there's uneven tread wear or if your vehicle pulls to one side.
  • Brakes - Brakes should be inspected as recommended in your manual, or sooner if you notice pulsations, grabbing, noises, or longer stopping distance. Minor brake problems should be corrected promptly.
  • Battery - Batteries can fail any time of year. The only accurate way to detect a weak battery is with professional equipment. Routine care: Scrape away corrosion from posts and cable connections; clean all surfaces; re-tighten all connections. If battery caps are removable, check the fluid level monthly. Avoid contact with corrosive deposits and battery acid. Wear eye protection and rubber gloves.
  • Emergencies - Carry some basic tools-ask a technician for suggestions. Also include a first aid kit, flares, and a flashlight. Consider buying a cellular phone.

Keeping Your Vehicle in Tune with the Environment

Car care is definitely a win-win situation. Besides helping the environment, a properly maintained and operated vehicle will run more efficiently, will be safer, and will last longer-up to 50% longer, according to a survey of ASE-certified Master Auto Technicians. The following tips should put you on the road to environmentally conscious car care.

  • Keep your engine tuned. A misfiring spark plug can reduce fuel efficiency as much as 30%. Follow the service schedules listed in your owner's manual. Replace filters and fluids as recommended.
  • Check your tires for proper inflation. Under inflation wastes fuel-your engine has to work harder to push the vehicle. Wheels that are out-of-line (as evidenced by uneven tread wear or vehicle pulling) make the engine work harder, too. Properly maintained tires will last longer, meaning fewer scrap tires have to be disposed.
  • Keep your air conditioner in top condition and have it serviced only by a technician certified competent to handle/recycle refrigerants. Air conditioners contain CFCs-gases that have been implicated in the depletion of the ozone layer. According to the Environmental Protection Agency, almost one third of the CFCs released into the atmosphere come from mobile air conditioners; some simply leaks out, but the majority escapes during service and repair-so it's important to choose a qualified technician.
  • Do-it-yourselfers: dispose of used motor oil, anti-freeze/coolant, tires, and old batteries properly. Many repair facilities accept these items. Or call your local municipal or county government for recycling sites. Never dump used oil or anti-freeze on the ground or in open streams.
  • Observe speed limits. Mileage decreases sharply above 55 mph.
  • Drive gently. Avoid sudden accelerations and jerky stop-and-go's. Use cruise-control on open highways to keep your speed as steady as possible.
  • Avoid excessive idling. Shut off the engine while waiting for friends and family. Today's vehicles are designed to "warm up" fast, so forget about those five-minute warm ups on cold winter mornings.
  • Remove excess items from the vehicle. Less weight means better mileage. Store luggage/ cargo in the trunk rather than on the roof to reduce air drag.
  • Plan trips. Consolidate your daily errands to eliminate unnecessary driving. Try to travel when traffic is light to avoid stop-and-go conditions. Join a car pool.

Remember, how your car runs, how you drive it, and how its fluids, old parts, and tires are disposed of all have serious consequences on the environment.

Great place and even better prices, had my oil changed for less than a express lube and half the wait time. They also inspected other issues and quoted me prices on parts that have been cheaper than anywhere else I have checked. Will be returning soon to have them replace them.


-John Mercer

Great garage. These guys rock! Great place to take your Mini Cooper.


-Kevin Bell

I am from Ohio visiting Savannah, my son that is in the army needed his car speedometer calibrated. Brought it to Dave, he tested it, found what was bad and repaired it the same day. Great job.


-Ken Herb

Customer service isn't dead after all. Speedy service and super friendly to boot!


-Jennifer V Adair

Dave and his staff are simply amazing! They will take care of you without breaking your pockets. I've never been to a shop where the mechanics are so helpful and personable. I was struggling to get an emissions test for an out of state vehicle. They took care of it right away! Thank you!


-Darius Johnson WSAV

I took my F-150 to these guys because it was giving me trouble cranking up. Dave and Scott were quick to diagnose the problem and get it running again. I have already recommended this place to several of my friends. These guys know what they're doing and they are fair. Two thumbs up!


-Sandy D. - Savannah, GA

Two Nuts and a bolt is the best auto shop in town, Hands Down! I drove up and Dave and his staff immediately started working on my car. He is the most honest mechanic I have ever dealt with and his prices are incredibly affordable. I've had a lot of other mechanics take advantage of my lack of knowledge about cars. I've had a few be very condescending and patronizing too: BUT NOT DAVE. He talks to you like your family and you leave his shop thinking you got the family discount too. My car will never go to another Mechanic. Only Dave at Two Nuts and a Bolt will do.


-Rhianna H. - Savannah, GA

I am new to the Savannah area and needed a good shop to take my car to when it started giving me problems. In brief, I decided to take my car to Two Nuts and a Bolt Garage and I was not disappointed. They were very honest and fixed my car the same day, for a reasonable price. I highly recommend Two Nuts and a Bolt!


-Ryan J . - Savannah, GA

These days it is hard to find a service center who you can trust and feel confidant taking your car to. 2 Nuts & a Bolt is without a doubt the best service and repair shop I have ever used. They are quick to diagnose and repair my vehicles and have demonstrated a straight forward approach to solving all of my service needs. Thanks to Dave and all of the staff for keeping me on the road.


-Sam F. - Savannah, GA

I spent several years making the trek to Charleston to have my Mimi Cooper serviced, then I discovered Two Nuts and a Bolt. Dave and his crew are just wonderful. He saved me major bucks by knowing that there was a warranty (or management letter?) on the airbag on my Mimi. Had to trek back to Charleston but the replacement was free. I depend on the "Nuts" to keep me on the road


-Freda R.- Tybee Island

It's hard to find a car shop that isn't going to rip you off and sell you things you don't need. I trust Two Nuts and a Bolt to take care of my car for a fair price and in a timely manner. I won't go anywhere else as long as I'm in Savannah.


-Terrance F. - Savannah, GA

Mini Coopers love this shop, I know mine does. Same day oil changes at a reasonable price. Drop off service is great.


-Laura F. - Savannah, GA

We started going to Two Nuts and Bolt shortly after we moved to Savannah from Tacoma Washington. Before them we never used a Garage type shop because of their reputations on not fixing vehicles right and causing more damage. But since, Savannah didn't have a Jaguar dealership we decided to give it a try. Dave's garage was certified on every kind of vehicle and very knowledgable, everyone one was friendly and showed great customer service. He fixed the problem right the first time and left a great impression in our hearts. Not to mention the prices are cheaper than any dealership we have ever gone to before. Two Nuts and a Bolt is the go to place for car repairs in Savannah. We have recommended him to plenty of friends and family and they all agree. We not only take our vehicles there for repairs but also for maintenance.


-Zach P. - Savannah, GA

I got my LR3 100k service done..they did a great job and saved me hundreds over the dealer price...this was my last experience but I use 2 NUTS & a Bolt for all of my four car needs. I have trusted them with my truck on many occaisions as well as my Jaguar.. I recomended them to my neighbor when he bought a 1980 mercedes and needed it worked on as well..They are great!!! nice as can be and fair pricing!
