Maintenance

Proper vehicle maintenance is key to keeping your car running smoothly and efficiently. At Hollenshade’s Auto Repair in Towson, MD, we offer expert maintenance services including oil changes, fluid flushes, and filter replacements to help extend the life of your engine, transmission, and other critical systems.

Oil Change

Engine oil provides essential lubrication, cooling, and cleaning to your engine’s internal components. Over time, engine oil breaks down and becomes contaminated. Failing to replace oil and filters at manufacturer-recommended intervals can lead to severe engine damage or failure.

Our technicians perform fast, professional oil changes using high-quality oil and filters that meet or exceed OEM standards.

Air Filter

The air filter removes dirt and other particles from the air drawn into the engine. A clean, consistent flow of air is essential to proper engine operation. As the air filter becomes contaminated, it restricts the flow of air to the engine which could increase emissions output as well as decrease fuel economy. Routine replacement of the air filter ensures clean, unrestricted air flow into the engine to help maintain performance.

Cabin Air Filter

The cabin air filter cleans the air that flows through your vehicle’s HVAC system. Over time, it collects pollen, dust, and pollutants, which can lead to unpleasant odors and poor airflow.

A clean cabin air filter ensures your heating and air conditioning work effectively and helps maintain healthy air quality in your vehicle.

Automatic Transmission Fluid

Transmission fluid lubricates and cools the internal components of your transmission. Old or dirty transmission fluid can cause slipping, hard shifting, overheating, or even transmission failure.

Routine transmission fluid changes help:

  • Prevent costly repairs
  • Extend transmission lifespan
  • Improve fuel efficiency

Transfer Case Fluid

The transfer case allows a vehicle to be placed into four-wheel drive by engaging the front wheels on a normally rear-wheel drive vehicle. Transfer case fluid plays a vital role in cooling and lubricating the components within the transfer case. Degraded or dirty transfer case fluid can increase friction within the transfer case causing components to wear potentially causing premature failure of the transfer case. Replacing the transfer case fluid at the recommended intervals helps ensure proper transfer case operation while in four-wheel drive and prevents premature transfer case failure.

Coolant Flush

Engine coolant is vital to maintaining optimal engine operating temperature. Deteriorated or contaminated coolant can cause poor fuel economy due to inefficient cooling of the engine, cause premature cooling system failures, and could potentially result in damage to internal engine components. Replacing engine coolant and flushing the cooling system at the recommended intervals ensures that the cooling system continues to perform properly and that the engine is not in danger of overheating or freezing.
