1. Tire Maintenance

Tires are the foundation of your vehicle’s performance and safety, making regular maintenance crucial for optimal driving experience.

Here’s why tire maintenance matters and how you can ensure your tires are in top condition:

Checking Tire Tread Depth, Pressure, and Wear:

Tire tread depth is vital for providing traction and grip on the road, especially in wet or slippery conditions. Insufficient tread depth can increase the risk of hydroplaning and reduce overall stability.

Monitoring tire pressure is essential for maintaining proper handling, fuel efficiency, and tire longevity. Underinflated tires can lead to increased rolling resistance, which negatively impacts fuel economy and wears out tires faster.

Generally most cars have a tire pressure range between 32 to 35 PSI. But consider checking the user manual for recommended pressure for your tires.

How to Inspect Tires for Signs of Uneven Wear and Alignment Issues:

Start by visually inspecting each tire’s tread depth using a tread depth gauge or the built-in wear indicators. Replace tires that have worn down to the minimum tread depth to maintain traction and grip on the road.

Check for signs of uneven wear, such as excessive wear on one side of the tire or in the center. These patterns may indicate misalignment, improper tire inflation, or suspension issues.

Perform a hands-on inspection by running your hands over the tire surface to feel for any abnormalities, bulges, or flat spots. Any irregularities should be addressed promptly to prevent tire failure while driving.

2. Brake Inspection

Maintaining your vehicle’s braking system is paramount for safe driving and overall vehicle performance.

Here’s a comprehensive guide to brake inspection, including how to visually inspect brake pads, monitor brake fluid levels, and detect potential brake problems early:

Visually Inspecting Brake Pads and When to Replace Them:

Start by visually inspecting the brake pads through the wheel spokes or openings. Many vehicles are equipped with wear indicators that make it easy to assess pad thickness.

New brake pads typically have around 10-12 millimeters of pad material. As the pads wear down, they should be replaced when they reach approximately 3 millimeters of thickness.

Look for signs of uneven wear or damage on the brake pads. If one pad appears significantly thinner than the others or if there are grooves, cracks, or chips, it’s time for replacement.

Listen for any squealing or grinding noises when braking, as these can indicate worn brake pads rubbing against the rotors. Ignoring these sounds can lead to brake rotor or disk damage and compromise braking performance.

Monitoring Brake Fluid Levels and Signs of Brake System Problem:

Regularly check the brake fluid level in the reservoir, located under the hood near the firewall (a panel between the engine compartment and the passenger compartment). Ensure the fluid level falls within the “min” and “max” marks on the reservoir.

Low brake fluid levels can indicate a leak in the system or excessive brake pad wear.

Soft or spongy brake pedal feel can be due to brake system issues and may indicate air in the brake lines, worn brake components, or fluid contamination.

Tips for Detecting Brake Problems Early:

Schedule regular brake inspections as part of your routine car maintenance. A qualified mechanic can perform a thorough inspection of the entire braking system, including pads, rotors, calipers, and brake lines.

Pay attention to any changes in brake performance or behavior, such as increased pedal effort, vibration, or pulling to one side when braking. These signs may indicate underlying brake issues that require immediate attention.

Remember: a bent brake rotor might lead to jerking sensations and uneven braking. Worn out suspension bushes and misaligned tires can cause vibration while braking at high speeds.

When replacing brake pads, consider upgrading to high-quality, ceramic brake pads for improved performance, longevity, and reduced brake dust.

3. Suspension and Shock Absorbers

Your vehicle’s suspension system plays a crucial role in providing comfort, stability, and handling on the road. 

Here’s what you need to know about inspecting suspension components and shock absorbers:

How to Check Shock Absorbers for Leaks and Visual Damage:

Start by visually inspecting each shock absorber for signs of leaks, such as oil stains or wetness around the shock body & axle. Leaking shock absorbers can compromise ride quality and handling.

Look for any visible damage, such as dents, cracks on the control arms, broken bushes or corrosion on the shock absorber housing. Damaged shock absorbers should be replaced promptly to ensure safe and smooth driving.

It is recommended to replace shock absorbers in pairs (Both Front or Both Rear) for a better ride quality.

Pay attention to any unusual noises, such as knocking or clunking sounds, when driving over bumps or rough roads. These noises may indicate worn or faulty shock absorbers or suspension bushes that need attention.

Maintaining Suspension Components for Comfort and Handling:

The suspension system consists of various components, including springs, struts, control arms, and bushings, all of which work together to absorb bumps and maintain tire contact with the road surface.

Maintaining suspension components is essential for ensuring optimal comfort, stability, and handling, particularly during cornering and braking maneuvers.

Worn suspension components can lead to excessive body roll, uneven tire wear, and reduced stability, compromising both safety and driving enjoyment.

Inspecting Suspension Without Removing Wheels:

While a comprehensive suspension inspection typically requires removing wheels and accessing suspension components, there are visual checks you can perform without lifting the vehicle.

Park your vehicle on a level surface and visually inspect the suspension components from underneath the vehicle. Look for signs of damage, rust, or excessive movement in bushings and joints. Turn the steering completely to one side for a better viewing angle.

inspect for leaks or damage on shock absorbers and other suspension components.

Perform a bounce test by pushing down firmly or by rocking the car on each corner of the vehicle and observing how it responds. A vehicle with healthy suspension should rebound smoothly, without any sound and excessive bouncing.

4. Under the Hood Inspection

Regular inspections inside the bonnet of the car are essential for maintaining your vehicle’s performance and reliability. Here’s a step-by-step guide to checking engine oil levels and identifying potential issues:

1. Start by parking your vehicle on a level surface and allowing the engine to cool down for a few minutes.
2. Locate the engine oil dipstick, usually indicated by a brightly colored handle, and remove it from the engine.
3. Wipe the dipstick clean with a cloth or paper towel to remove any oil residue.
4. Reinsert the dipstick fully into the dipstick tube, then withdraw it again to check the oil level.
5. Read the oil level by observing the markings or indicators on the dipstick. The oil level should fall between the “min” and “max” marks or within the cross-hatched area.
6. If the oil level is low, add the appropriate type and viscosity of oil as recommended by the vehicle manufacturer. Be careful not to overfill the oil reservoir.
   
   Newer cars come with digital sensors where the reading can be observed directly from the infotainment system.

Coolant and Windshield Washer Fluid:

In addition to engine oil, it’s crucial to monitor other vital fluids, such as coolant and windshield washer fluid.

Check the coolant level in the coolant reservoir or radiator, ensuring it falls within the recommended range. Low coolant levels can lead to engine overheating and potential damage.

Inspect the windshield washer fluid reservoir and refill it as needed to ensure clear visibility while driving in various weather conditions.

Signs of Fluid Leaks and Engine Issues:

Perform a visual inspection of the engine compartment for any signs of fluid leaks, such as puddles or stains on the ground beneath the vehicle.

Check for oil leaks around the engine oil pan, valve cover gasket, and other gaskets or seals. Look for coolant leaks around radiator hoses, water pump, and heater core.

The coolant level is not supposed to drop in a closed loop system. However if you notice a decrease in coolant level it is usually signs of leak. Make sure the coolant cap is tightly secured and the engine is at ideal temperature. If you find white smoke within the engine compartment and at the exhaust it is signs of coolant leak. Radiator fluid/Coolant contains ethylene glycol, which is similar to sugar compounds and causes a sweet smell when burning.

If you notice the engine oil changing to a milky white color, it’s typically an indication of coolant or radiator fluid mixing with the oil. In such cases, you must not drive the vehicle and get it inspected by a mechanic.

Listen for any unusual noises coming from the engine, such as knocking, ticking, or hissing sounds, which may indicate engine issues that require attention.

Pay attention to warning lights on the dashboard, such as the check engine light or low oil pressure light, as these may indicate potential engine problems.

5. Air Filter Maintenance

Proper car filter maintenance is vital for keeping your vehicle running smoothly and ensuring a comfortable driving experience.

Here’s what you need to know about inspecting and replacing engine air filters, checking cabin air filters, and maintaining wiper blades:

Inspect and Replace Engine Air Filters for Optimal Engine Performance:

Start by locating the engine air filter housing, usually located near the front of the engine compartment.

Remove the air filter housing cover and carefully inspect the condition of the air filter. Look for signs of dirt, dust, or debris that may be restricting airflow to the engine.

If the air filter is dirty or clogged, replace it with a new one. Most engine air filters are disposable and should be replaced according to the manufacturer’s recommended intervals or every 15,000 to 20,000 kilometers.

Installing a clean air filter ensures proper airflow to the engine, improving fuel efficiency, engine performance, and prolonging engine life.
