The Basics Behind 90,000 Mile Service at Masterwerks

Masterwerks is the leading 90,000 mile service shop in Phoenix, AZ, proudly serving Maricopa County, Pinal County, and surrounding areas. We’re dedicated to ensuring your vehicle runs at peak performance while keeping you and your family safe on the road. In the demanding driving conditions of Maricopa County, following the manufacturer’s recommended preventative maintenance schedule is essential to protect your vehicle’s longevity and preserve your factory warranty.

At the 90,000 mile service interval, manufacturers require a comprehensive evaluation of critical vehicle systems. Our trained ASE-certified mechanics focus on performing only the necessary services and repairs, ensuring your vehicle remains reliable—all at a fraction of the cost charged by dealerships.

Before every 90,000 mile service, we perform a Quality Assurance Road Test to verify that your vehicle is handling and performing at its best. If our technicians detect any unusual sounds or handling irregularities, we conduct a more in-depth inspection on the lift and discuss further diagnostics with you.

Our 90,000 Mile Service Process

At Masterwerks, our 90,000 mile service is a thorough, multi-point inspection designed to address every vital component of your vehicle’s maintenance. Our service includes:

• Quality Assurance Road Test:
  We begin with a comprehensive road test to detect any issues with handling or performance before proceeding with the service.
• Engine Oil and Filter Replacement:
  In the harsh Maricopa County environment, frequent oil and filter changes are critical to maintain engine lubrication and protect internal components, keeping your warranty intact.
• Steering Linkage and Boots Inspection:
  We inspect the steering linkage and boots for excessive play to ensure rapid and safe response during emergencies while preventing uneven tire wear.
• Drive Shaft Boots Examination:
  Our technicians check that your drive shaft boots are intact—free of damage, tears, or dry rot—to maintain proper lubrication and avoid expensive repairs.
• Engine Coolant Evaluation:
  We verify the condition and level of your engine coolant, ensuring the system is leak-free and functioning properly—even extended life coolants degrade over time under harsh conditions.
• Brake System Assessment:
  A detailed inspection of brake linkages, drums, pads, and discs is performed to guarantee your braking system operates reliably, preventing costly rotor damage and ensuring your safety.
• Reset Maintenance Reminder:
  If your vehicle features a maintenance reminder system, we reset it so you’re promptly notified at your next service interval.
• Air Filter Replacements (Engine & Cabin):
  Clean air is critical—our service replaces clogged engine and cabin air filters to improve engine performance, fuel efficiency, and interior air quality.
• Chassis Bolts and Nuts Inspection:
  We check the chassis and suspension components for loose bolts and irregular wear to catch potential issues early and maintain overall vehicle integrity.
• Tire Inspection, Rotation, and Inflation:
  Proper tire care is vital for handling and fuel economy. We inspect, rotate, and ensure optimal tire inflation to promote even wear and maximize tire life.
• Exhaust System Evaluation:
  We inspect exhaust pipes and mountings for leaks or damage that could impair engine power or fuel economy, ensuring that harmful fumes are safely expelled.
• Fuel System Check:
  Our service includes a thorough inspection of fuel lines, connections, and the vapor recovery system to detect any leaks or safety hazards early.
• Transmission Fluid Inspection:
  We examine the condition and level of your transmission fluid, checking for leaks and discoloration, which could lead to internal transmission damage if left unaddressed.
• Brake Lines and Fluid Evaluation:
  We ensure your brake fluid and lines are properly maintained, preventing pressure loss that can lead to brake failure.
• Power Steering Fluid Inspection:
  Regular checks of the power steering fluid help avoid seal failure and costly rack repairs due to moisture or low fluid levels.
• Spark Plug Replacement:
  Faulty spark plugs can lead to engine misfires and reduced performance. We replace them as needed to ensure optimal combustion and fuel efficiency.
• Four Wheel Drive & All Wheel Drive Systems (if applicable):
  For vehicles equipped with these systems, we inspect and, if necessary, replace the fluids in the transfer case, front differential, and rear differential to maintain drivetrain reliability.
