car maintenance checklist

Suppose your Clermont Toyota has reached 500,000 miles. Welcome to the club! This is a huge achievement considering most people sell their ride before this happens. Having your car reach this milestone means that you have a solid car maintenance checklist that you probably follow. However, if you need more car maintenance tips on your high-mileage car, we’re “Making it Simple™” for you at Toyota of Clermont. We’re covering how to keep your high-mileage car strong, what to watch for, and why you can’t afford to skip this auto service.

Essential Car Maintenance Checklist at 500,000 Miles 

If you’ve made it this far in your ride, you should be super proud of yourself. Here’s a car maintenance checklist to watch out for:

Engine Care 

  • Oil & Filter Changes: First, it’s best practice to stick with routine car maintenance every 5,000-7,500 miles. However, if you notice any problems with your car, you should swing by Toyota of Clermont to get your ride checked out ASAP. A key tip to remember is to use high-mileage synthetic oils with additives that condition seals and reduce sludge.
  • Compression Test: Also, ensure your auto mechanic performs a compression test to check for worn piston rings or valves. This is super common as your vehicle ages.
  • Valve Adjustment: One thing that’s common to slip your mind is making sure that you get your valves adjusted if they require this auto service.

Transmission & Drivetrain 

  • Fluid & Filter Change: The next item on your car maintenance checklist is to make sure you replace transmission fluid and filter every 30,000-50,000 miles. Old fluid can create slipping, overheating, and car failure.
  • Leaks: Another item on your car maintenance checklist is checking for car leaks. Especially in the seals and gaskets around the pan and driveshaft.
  • Differential & Transfer Case: Be sure to change car fluids to prevent gear wear and tear and overheating.

Cooling System 

  • Coolant Flush: Flushing and replacing your car’s coolant every 50,000 miles is best practice, too! Old car coolant can corrode the radiator, heater core, and engine block.
  • Inspect Hoses & Radiator: Additionally, check all hoses that appear soft, cracked, or bulging. And, double-check that radiator for any leaks or corrosion.
  • Thermostat & Water Pump: If this is going bad, you should have a replacement ASAP, because this can destroy your car engine.

Brakes 

  • Brake Fluid Flush: Also, have a brake fluid flush every 2-3 years. Old fluid absorbs moisture, which leads to corrosion and brake failure.
  • Inspect Pads, Rotors, Calipers, & Lines: Have your auto mechanic check for worn parts and check for leaks. Plus, pay special attention to the steel brake lines that are prone to rust.

Suspension & Steering 

  • Inspect & Replace Worn Parts: Auto parts that you should watch for on your car maintenance checklist are shocks, struts, bushings, ball joints, tie rods, and wheel bearings.
  • Alignment: Additionally, check out the wheel alignment at Toyota of Clermont, as this can lead to tire wear and improper handling.

Belts, Hoses, & Seals

  • Serpentine & Timing Belts/Chains: Also, check out what your car manufacturer says about when to replace these auto parts!
  • All Hoses: Next, be sure to replace car coolant, vacuum, and fuel hoses that can degrade over time.
  • Engine & Transmission Seals: Watch out for any oil or transmission fluid leaks.

Fuel System 

  • Fuel Filter: Checking your fuel filter on your car maintenance checklist is another super important task!
  • Injectors & Pump: Plus, clean injectors and test the fuel pump to make sure it has the proper pressure and flow.
  • Tanks & Lines: Watch out for any rust or leaks, which are more common as your car ages.

Electrical System 

  • Battery: The next item on your car maintenance checklist is the car battery. Test and replace your car battery if it’s weak.
  • Alternator & Starter: Also, test the output and replace the car alternator and starter if these show signs of failure.
  • Wiring & Grounds: Be sure to inspect this for corrosion, loose connections, and proper installation.

Exhaust System 

  • Leaks & Rust: Additionally, replace any rusted pipes, mufflers, and catalytic converters. Leaks can be super dangerous and cause you to fail your emission test.
  • Oxygen Sensors: Listen to the advice of your mechanic and replace these for fuel efficiency and emission control.

Tires & Wheels 

  • Tires: Another super important auto part to mark off your car maintenance checklist is the car tires! Watch out for any uneven tire wear, dry rot, and tread separation.
  • Wheel Bearings: Keep an ear out for any odd noises and replace these if needed.
  • Alignment & Balancing: Checking your wheel alignment and balancing is super important to ensure a smooth ride.

Body & Undercarriage 

  • Rust Inspection: Also, be sure to watch out for any rust along the frame, brake lines, and mounting points.
  • Weatherstripping & Seals: Replacing these items is important as it prevents water leaks and wind noise.
