Maintenance Your Car Needs After Driving 100,000 Miles

Your car requires careful maintenance to keep it humming. To help you remember to maintain all the aspects of your car that require attention, many people recommending handling a few hallmarks around the 100,000-mile mark. Here’s a guide to the maintenance your car needs after driving 100,000 miles, along with the reasons maintaining your car will benefit you in the long run.

Check Your Spark Plugs

First, while copper spark plugs last 20,000 miles, it’s common for other spark plugs to last between 80,000 to 100,000 miles. If you haven’t already, inspect your spark plugs. Your spark plugs begin the ignition process when you turn your key, and upon repeated use, they wear out, overheat, and gather buildup. When this happens, your spark plugs don’t function properly and cause your engine to misfire and ratchet up your gas consumption. If you fail to replace your spark plugs—a manageable cost—you could face a more significant and expensive issue, such as a failing catalytic converter.

Look into Replacing Your Serpentine and Timing Belt

Another service your car typically requires after 100,000 miles is replacing your serpentine and timing belts. It’s possible, like spark plugs, that your belts are new already. If they aren’t, they may show signs of wear. Your serpentine belt, which powers your alternator, power steering pump, and air conditioning, may become brittle and crack around 100,000 miles. Meanwhile, your timing belt—which regulates engine function—can cause costly damage to your engine if you don’t service your belt.

Assess Your Brakes

Additionally, you should check your brakes at 100,000 miles. Like a timing belt, spark plugs, and many more parts, not changing your brakes on time means you’ll likely need more expensive servicing if you damage your rotors. There are a couple of signs you need to replace your brake pads, including a squealing sound occurring when you apply the brake.

Replace Certain Fluids

There are several long- and short-lived fluids you should replace around 100,000 miles, including the following:

  • Engine Coolant
  • Brake Fluid
  • Engine Oil
  • Transmission Fluid
