Everything You Need To Know About The 90K Mile Service | B&C Auto Center

When your vehicle hits the 90,000-mile mark, it's quite a milestone - but there is a twist. The 90K-mile service is a crucial maintenance checkpoint that should not be overlooked. This comprehensive service ensures your vehicle continues to operate smoothly, efficiently, and safely, far beyond this significant odometer reading. 

Importance of the 90K Mile Service

Reaching 90,000 miles is a testament to your vehicle's reliability and durability. However, to maintain this level of performance, specific maintenance tasks must be performed. This service is designed to address the wear and tear accumulated over tens of thousands of miles of driving, preventing major mechanical issues and extending the life of your vehicle.

What to Expect: Key Components of the 90K Service

The 90K-mile service typically includes a thorough inspection and possible replacement of critical components such as timing belts, spark plugs, and fluids. This service might also involve:

  • Inspecting and possibly replacing the water pump
  • Checking the braking system
  • Tires
  • Suspension components
  • Ensuring the engine and transmission are in good working order

Each vehicle manufacturer might have specific recommendations, so it's essential to consult your owner's manual or a trusted mechanic.

Timing Belt - A Critical Checkpoint

One of the most crucial aspects of the 90K-mile service is inspecting and possibly replacing the timing belt. A worn timing belt can lead to catastrophic engine failure if not addressed, making its inspection and replacement critical at this service interval.

Fluids and Filters

Fluids and filters play a pivotal role in your vehicle's performance. The 90K service should include checking and replacing the engine oil, coolant, transmission fluid, brake fluid, and power steering fluid if necessary. Additionally, air and fuel filters need inspection and replacement to ensure optimal air-fuel mixture and engine efficiency.

Brakes, Tires, and Suspension

The safety components of your vehicle, such as brakes, tires, and suspension, require close attention during the 90-mile service. Brake pads, rotors, tire tread depth, and tire pressure should be checked, along with suspension components for wear or damage, to ensure the vehicle's safety and handling characteristics are maintained.

The Role of a Professional Mechanic

While some maintenance tasks can be performed by a skilled DIYer, the comprehensive nature of the 90-mile service often necessitates the expertise of a professional mechanic. They can perform a detailed inspection, diagnose any underlying issues, and ensure all service components meet the manufacturer's specifications.

Beyond the 90K Mile Service

After completing the 90K mile service, it's essential to plan for future maintenance. Regular check-ups, adhering to the manufacturer's service schedule, and addressing any issues promptly can help ensure your vehicle remains reliable, efficient, and enjoyable to drive for many miles to come.
