Engine Service and Repair
The engine is responsible for converting fuel into power, helping your car run smoothly. The engine is the most complex component in your vehicle and requires professional care from certified mechanics. Below are key engine services we provide at our West Chester repair center.
Engine Oil and Filter Replacement
The engine oil lubricates the moving components of the engine, reducing friction and helping prevent overheating. The oil filter ensures that clean oil reaches your engine while filtering out contaminants. The engine oil and filter should be replaced at manufacturer-recommended intervals to maintain optimal performance.
Timing Belt/Chain Inspection and Replacement
The timing belt or chain synchronizes the crankshaft and camshaft in your engine, ensuring the valves open and close in sync with the pistons. Over time, wear and tear can cause the timing belt or chain to lose proper tension or alignment. You should have it inspected and replaced as recommended in your vehicle’s owner’s manual.
Flashing Check Engine Light
When the check engine light illuminates on your dashboard, it indicates underlying issues that need immediate attention. A flashing light is often caused by a faulty O2 sensor, failing catalytic converter, or engine misfire. If your check engine light comes on, contact Dougherty Automotive in West Chester, PA, for inspection and repair by our certified mechanics.
Transmission Service and Repair
The transmission system transfers power from the engine to your car’s wheels. Whether your car has an automatic or manual transmission, it’s a complex system that requires regular maintenance to operate efficiently. At Dougherty Automotive in West Chester, PA, we offer all essential transmission services.
Transmission Fluid Flush and Filter Change
Transmission fluid lubricates the gears, clutches, and bearings within the transmission system and provides hydraulic pressure for smooth gear shifting. Contaminated fluid can cause shifting issues or internal wear, so it’s important to follow your manufacturer’s recommended service schedule.
Slipping Gear
Transmission problems often become apparent when you experience gear slipping, which is when the engine revs but the transmission fails to engage properly. This can result from low transmission fluid, worn clutches, or internal component failure. Reach out to Dougherty Automotive to have our professionals address gear slipping issues promptly.
Transmission Warning Light
Like the check engine light, the transmission warning light monitors the system’s performance. If it illuminates, it indicates a potential issue that needs diagnosis. Identifying the cause of the warning light is the first step in resolving transmission problems. Contact Dougherty Automotive to have your transmission inspected and repaired by professional technicians.
