In wet weather, you depend on your windshield wipers for clear visibility. It's hazardous if they suddenly stick, smear, bend, or break. Here are some early indications that you need wiper service and replacements at your local Buick dealership. 5 Signs It's Time for a Buick Wiper Blade Replacement Cracking or Fraying The rubber in windshield wipers gradually stiffens and dries out as it ages, which causes cracks and damage. If your wiper rubber looks cracked, frayed, or split from the frame, it's time for replacements. more Inspect your wipers regularly for this kind of damage, especially before and after winter; you'll need strong wipers for winter when intense cold, frost, and snow can harm wipers considerably. UV rays during summer can also damage wiper rubber. Bent Wiper Frame Buick windshield wipers are tailored precisely to the size, shape, and curve of each model's windshield to flow smoothly over the glass. If an aging wiper's frame warps or bends out of shape even fractionally, the rubber no longer hugs the glass snugly. This renders the wiper ineffective and no longer safe to use. Streaking or Smearing When wipers are damaged or wearing out from age, they typically fail to wipe water from as much of the windshield as they should. This means they leave wet streaks or smears across the glass, which hinders driver visibility. Any kind of streaking or smearing means you need new wipers at once. Chattering and Jumping Both extreme heat and cold can stiffen wiper rubber, which can eventually cause wipers to chatter across the glass rather than wipe smoothly. This chattering means the wiper is making lots of little jumps, leaving unwiped vertical stripes on the windshield. To minimize this phenomenon, it's a good idea to buy special winter wipers at the end of fall. Winter wipers have special cold-resistant rubber that remains pliant even in freezing temperatures. Squeaking or Slapping Your wipers should do their job quietly. As with most car parts, an increase in noise probably means trouble; one or both of your noisier wipers is wearing out. Aging wipers may start to squeak loudly. If the rubber element has pulled away from the frame, they can make slapping noises. Schedule Wiper Service at Our Buick Dealership Today Let our experienced professionals inspect and replace your windshield wipers. Given how affordable wipers are compared to some other vehicle components, it's never worth delaying wiper replacements; remember, even slightly reduced visibility on a rainy day raises your risk of a collision. Faulty wipers sometimes also emit rattling sounds. Visit Vachon Buick GMC in Old Saybrook, CT, today for new windshield wipers. We're an award-winning local dealership that places great emphasis on customer satisfaction in all that we do.

Regular alignments are as important as rotations for maintaining your tires. While rotations switch your tires around to keep them even, alignment sets them straight, returning each wheel to a perfectly parallel position. It's a good idea to book an alignment service twice a year at your local Buick dealership. Tire Alignment Service Offered at Your Buick Dealership Why Tires Become Misaligned Whenever your tires are bumped or jolted by potholes, curbs, or rocky surfaces, they become ever-so-slightly less perfectly aligned. This means the suspension holding each wheel in place has been adjusted. Uneven tires also push themselves out of proper alignment. For most drivers, it takes a long time for tires to become noticeably misaligned, when their handling and steering eventually start to suffer. more The Three Angles of a Car Tire Tire alignment is measured on three angles. The toe angle can be seen from above and measures whether the tires are pointed inward or outward, which would steer the tire toward the left or right. The camber angle is seen most clearly from the front of the car, measuring whether the tops of the wheels are leaning inward or outward. The caster angle, which can be seen from the side, measures whether the wheel's steering axis is tilted forward or backward. Problems Caused By Bad Alignment When car tires aren't straight anymore, steering can become looser and less accurate, and the vehicle may veer off to one side. The tires will also develop uneven wear patterns, which lessens traction and heightens the risk of blowouts. Your car's overall road noise and vibrations will also increase, along with rolling resistance and fuel costs. Eventually, your wheels will look clearly crooked, especially when viewed directly from the front. First, Measure Your Alignment Naturally, drivers who spend most of their time on well-maintained highways tend to have better alignment than frequent off-roaders. As alignment issues vary from driver to driver, you'll need to have the angles of each wheel measured regularly to determine how it's doing. It makes sense to have an alignment check carried out twice a year, each time you have your tires rotated. Correct Your Alignment When Needed If any of your wheels are found to be out of alignment, it's time to correct them. Your car will be raised, and an alignment machine will be attached to each wheel. This machine measures the three angles very precisely, providing computerized readouts that our mechanic can use to adjust the suspension, bringing each wheel back into its original factory alignment. The entire process rarely takes longer than an hour. Test the alignment of your tires today at Vachon Buick GMC in Old Saybrook, CT.

The powertrain of your GMC includes the engine, transmission, driveshafts, differentials, and axles. To ensure your truck or SUV generates and delivers full force to the wheels with optimal efficiency, each drivetrain component must be kept in tip-top shape with regular preventative maintenance at your local GMC dealership. Here's an outline of what's involved in good powertrain care. Oil Changes and Engine Tune-Ups As the seat of your GMC's impressive power, the engine must always be well-lubricated with high-quality motor oil. This means routine oil changes twice a year or more. You should also have the engine examined and tuned up once a year. Cooling System Inspections Every component of the cooling system also needs to be professionally inspected once a year. In addition, it's wise to check the condition of your coolant monthly and have it flushed every two years. more Air Filter Replacements When the engine air filter becomes blocked by an accumulation of airborne debris, the cylinders can no longer draw in sufficient oxygen to operate properly. Replace your air filter once a year and check it periodically. Transmission Services The gearbox and clutch transmit the engine's power to the axles and wheels. Automatic transmissions are extremely complex and require yearly inspections. You'll typically need to flush the transmission fluid every 60,000 to 100,000 miles. Driveshaft Inspections The driveshaft is an often-overlooked part of the drivetrain that nevertheless serves a vital function. Ensure your driveshafts are properly lubricated and undamaged with yearly inspections. Differential Fluid Flushes A smaller gearbox exists inside each of your car's differentials that also requires high-quality fluid. You'll need to have your differential seals, gears, and fluid checked once a year. Axle Seal and Bearing Checks The axle seals and wheel bearings at the front and rear of your car need to be checked yearly. You'll occasionally need to replace both seals and fluid. Transfer Case Maintenance With all-wheel or four-wheel drive models, you'll also have a transfer case to maintain. This component transfers power to both the front and rear axles, playing a key role in the drivetrain. If your vehicle has a transfer case, the fluid inside requires flushing every 25,000 miles or so. Schedule Routine Powertrain Care with Us The considerable power and dependable performance of your GMC truck or SUV will continue for many years and possibly even decades with regular service. Allow us to take good care of your drivetrain for you. With routine scheduled maintenance, we'll minimize the risk of parts wearing out or failing prematurely.
