Buick builds cars with enormous longevity, provided they are looked after with proper routine services. If you follow the Buick maintenance schedule laid out below, there’s every reason to expect you’ll still be driving your Buick for 250,000 or even 300,000 miles.
Monthly Maintenance Tasks
Tires need frequent attention; check the air pressure inside each tire once a month, keeping the PSI to the level recommended in your owner’s manual. You should also check the coolant level and condition once a month, plus that of the motor oil. Keep the windshield wiper fluid topped up once a month and check all external lights as well.
Checks Every Three Months
Four times a year, it’s advisable to check the battery and cables for signs of corrosion or weakening, especially if the battery is past three years of age. Also, inspect the belts and hoses for signs of wear and tear and check the power steering fluid and windshield wipers for signs of aging.
Maintenance Every Six Months
You’ll need to keep your motor oil fresh by changing it every six months or even sooner if you drive more than most. Also, have your tires rotated twice a year. At the six-month mark, you’ll need to have your brakes and exhaust system professionally inspected and repaired if necessary.
Maintenance Every Two Years
Each component of the ignition system should be examined and tested every two years. This includes the ignition coils, spark plugs, wiring, and more. Your fuel injector might also need to be replaced at this interval.
Less Frequent Maintenance
Your coolant should typically be completely flushed every 60,000 miles. You may need to flush your transmission fluid every four years, although this hardy fluid can last much longer, as much as 100,000 miles, about seven years, in modern automatic transmissions.
Your tires will probably need replacing at around the four or five-year mark, as will the battery. The timing belt usually lasts 60,000 to 90,000 miles, which means a replacement every four to six years for most drivers.
If you drive more than most or in severe conditions, you’ll also need to adapt your maintenance schedule. Allow us to help you plan and carry out an optimal personalized servicing schedule.
