Skipping an oil change may seem harmless but can lead to significant engine trouble. With this in mind, it's wise to keep your oil in tip-top condition with routine changes at your local Buick dealer or GMC dealer. more The Importance of Regular Oil Changes for Your Buick or GMC Prevent Overheating The nemesis of all car engines is overheating. By lubricating and reducing friction, motor oil plays a large role in controlling the engine's temperature. If you neglect to change your oil, it will degrade and fail to lubricate properly, leaving the coolant alone to combat the rising heat. Optimize Lubrication Motor oil performs its lubricating and cleaning functions best when fresh. As the months pass, motor oil collects particles of dirt, metal shavings, and carbon deposits, which cause it to gradually thicken. Regular changes keep the oil's lubricating and cleaning qualities optimized at all times, which keeps your engine well-protected. Boost Fuel Efficiency When motor oil is functioning properly, the engine works at maximum output capacity. This means optimized gas mileage. And if the oil begins to degrade, you'll soon find yourself stopping more often for gas. Enhance Performance Your car's overall power and performance are also dependent on the motor oil. The better condition the oil is in, the better acceleration and overall handling you'll enjoy. Fewer Repairs Any repair work related to the engine can be costly. As motor oil is your engine's number one defense against wear and tear, it helps each moving component last longer. This reduces your long-term expenses on faults and part replacements. How Frequently To Change Oil at Your Buick Dealer For the majority of drivers, it's suitable to change oil twice a year. However, if you commute daily in heavy traffic, use your car mostly for very short trips, or put your motor oil under additional pressure in any other way, you may need more frequent oil servicing than this.

Combustion produces large quantities of heat, and the radiator acts as a heat exchanger to remove this heat by replacing it with cooler outside air. The radiator and the rest of the cooling system operate under high pressure and in high-temperature conditions. Over time this can cause damage to the system. As your Buick dealer and GMC dealer, we'd like you to know a few signs that you need to visit us for a radiator repair. Signs You Need a Radiator Repair at Your GMC Dealer or Buick Dealer Engine Temperature Rising The temperature gauge on your dash gives you a heads-up on your engine temperature. As you accelerate, the engine temperature will rise and the cooling system will speed up to reduce the temperature again. Although your engine works most effectively at a temperature between 185 F and 230 F, this sustained heat level will damage sensitive engine components like gaskets and seals. If your engine temperature rises for no apparent reason and continues to climb, this is a sign of danger. An engine can suffer serious, even fatal damage if the temperature isn't reduced. We advise pulling over as soon as it's safe to do so and contacting us right away. Our expert technicians will find the cause of the problem and repair it. more Damaged Radiator Fan Liquid coolant is pumped through the engine and absorbs heat as it moves. This heat is trapped inside the coolant and transported to the radiator. Inside the radiator, the flow of cool air through the radiator grille removes the heat from the coolant. When you're idling, airflow through the grille is very restricted. In this situation, the radiator fan at the back of the radiator switches and blows the heat inside the coolant out through the radiator grille. If the radiator fan fails, your engine will start to overheat any time the engine is idling. Coolant Leaks A coolant leak is generally very easy to spot as coolant is available in bright colors like pink, blue, and green. If you have a coolant leak, we advise that you contact our service department ASAP. If you drive while your engine is leaking coolant, your engine can rapidly overheat. A coolant leak can be caused by a rusted radiator, a leaking radiator hose, or a damaged radiator cap. We'll examine your cooling system, find the cause of the trouble, and fix it.
