Car Maintenance Checklist: How to Inspect Your Vehicle

1. Check Fluids and Oil

Fluids really are the lifeblood of your vehicle. To start your inspection, check and top off the following important fluids:

• Engine oil – Check the dipstick at least once a month, as well as before you leave on a long trip. If the oil looks dirty or low, it’s time to change it. You can do this yourself or have it professionally serviced. Regardless of what you see on the dipstick, change your oil every 5,000 to 7,500 miles.
• Coolant – Look at the overflow reservoir. If the level is low, refill it with the correct coolant mixture.
• Brake fluid – Low fluid might indicate a leak in your system. If the fluid is dark or murky, flush and replace it. If you’re unsure, have a mechanic evaluate your care to ensure safety.
• Transmission fluid – Inspect the level and color of your transmission fluid. It should be bright red, not brown or burnt.
• Power steering fluid – Check and make sure you have adequate levels and no leaks.
• Windshield washer fluid – Try to keep the reservoir full to maintain clear visibility through your windshield.

Pro tip: Make sure you have a leak-free engine bay by using high-quality gaskets and seals from Rogo Fasteners.

2. Inspect Tires for Wear and Pressure

Effective tires are paramount for adequate efficiency, superior handling, and of course safety. It’s important to regularly inspect your tires for things like:

• Tread depth – A good way to test your tread depth is with the penny test. Just insert a penny into the tread with Lincoln’s head down. If you can see the top of his head, it's time for new tires.
• Uneven wear – If you notice uneven wear, it could be an indication of alignment or suspension issues.
• Proper inflation: Check your tire pressure with a gauge every month. Under-inflated tires wear out faster. They also reduce fuel efficiency.
• Cracks or bulges – If a tire has cracks or bulges, these are signs of aging or damage that require replacement.
• Rotation schedule – Make sure you rotate your tires every 5,000-7,500 miles for even wear.

Pro tip: Why not keep a tire pressure gauge in your glove box for quick checks?

3. Test Battery and Electrical Components

Nobody wants a dead battery. It can leave you stranded at home or on the road. You can make sure your car’s electrical system is in top shape by checking:

• Battery terminals – Clean any corrosion and make sure you have a tight connection.
• Voltage levels – Use a multimeter to check your voltage levels. A fully charged battery should read 12.6 volts or higher when the engine is off.
• Alternator performance – If your battery drains quickly, your alternator may not be charging properly. You can test it with a multimeter or have it professionally checked at an auto parts store or mechanic.
• Headlights, brake lights, and signals – At any point, you should replace dim or non-working bulbs.
• Fuses and wiring – Look for frayed wires or blown fuses, then replace them as needed.

Pro tip: You can keep your battery more secure with battery terminal connectors.

4. Brake System Inspection

There’s no doubt: brakes are your car’s most critical safety component. They should be inspected at least once a year or every 12,0000 miles. However, you might need to inspect them more often depending on your vehicle and driving habits.

To inspect your brakes, check for:

• Brake pad thickness – If your brake pads are less than 1/4 inch thick, it’s time to replace them.
• Brake rotors – When inspecting your rotors, look for scoring or uneven wear.
• Brake fluid level – Low fluid might indicate worn pads or a leak. If you don’t see the cause of the low fluid, you might want to have your car serviced by a mechanic.
• Unusual noises – Be cognizant of the sounds your brakes make. Squeaking or grinding suggests worn-out pads.
• Spongy pedal feel – If your pedal feels spongy, it could mean there is air in the brake lines or a failing master cylinder.

Pro tip: Use brake cleaner spray to remove dust and extend the life of your brake pads.

5. Inspect Belts and Hoses

It’s just a fact of life: rubber components degrade over time. When inspecting your vehicle, be sure and check:

• Serpentine belts – Look for cracks, fraying, or looseness in your serpentine belts.
• Timing belt – Replace at manufacturer-recommended intervals. This is usually between 60,000 and 100,000 miles.
• Coolant hoses – Gently squeeze your coolant hoses. If they feel brittle or too soft, then it’s time to replace them.
• Vacuum hoses – Listen for hissing sounds that may indicate a leak. As with other

Pro tip: You can extend the life of your hoses with hose clamps and fasteners from Rogo Fasteners.

6. Check Suspension and Steering

A well-maintained suspension system is so important to ensure smooth handling of your vehicles. A few things to inspect include:

• Shocks and struts – Push down on the car’s front and rear. If it bounces excessively, the shocks are worn and need replaced.
• Ball joints and tie rods – Look for excessive play as you drive to assess the condition of ball joints and tie rods.
• Alignment – If your car pulls to one side, an alignment check is needed. If it’s out, you’ll want to take your car to a tire shop or a mechanic for a realignment.
• Bushings – You often can recognize cracked or worn bushings because they create clunking noises and rough handling.

Pro tip: Regularly grease suspension components with lubricant for smoother operation of your vehicle.

7. Replace Air Filters

A clogged filter negatively affects engine performance and fuel efficiency. You can inspect for issues by checking things like:

• Engine air filter – Inspect this part every 15,000-30,000 miles – or sooner if you live or drive in dusty conditions.
• Cabin air filter – Also replace your cabin air filter every 15,000-30,000 miles for clean air inside the car. Clean it sooner if it’s dirty.

Pro tip: When it’s time for a replacement, you can ensure clean airflow with a reliable filter clamp.

8. Inspect Wipers and Windshield

Good visibility is critical for safe driving. To inspect your windshield and wipers, look for:

• Worn wiper blades – Replace these every 6-12 months or sooner if they leave streaks.
• Cracked windshield – Even small chips can spread, reducing visibility. Monitor your windshield for flaws and damage.
• Washer nozzles – Make sure they spray properly, and they’re not clogged.

Pro Tip: Use silicone wipers for better durability.

9. Check Exhaust System

A faulty exhaust affects fuel efficiency and emissions. Exhaust system issues may require a trip to the local mechanic. You can catch these problems by inspecting the following:

• Leaks – Look for rust or holes in the exhaust pipes.
• Loud noises – A rattling sound could mean a broken hanger or loose heat shield.
• Unusual smells – A sulfery, rotten egg smell might be a sign of a failing catalytic converter.

Pro tips: Use exhaust nuts and studs from Rogo Fasteners for secure fitting.

10. Review Safety Equipment

Safety equipment will help get you back on the road in a pinch. You want to be sure that your car’s emergency gear is in place:

• Spare tire – This needs to be properly inflated with the necessary tools.
• Jack and lug wrench – Ensure those equipment works so you aren’t stranded by a flat tire.
• Emergency kit – Make sure your kit includes jumper cables, a flashlight, a first-aid kit, and reflective triangles.
• Fire extinguisher – Keep a small automotive-rated extinguisher in the trunk. You just never know when you might need it.
