6 Commonly Overlooked Car Maintenance Jobs That Could Cause Big Problems

Ignoring a vehicle’s maintenance schedule significantly increases the risk of mechanical failure. Here we look at six routine car maintenance tasks that help drivers to keep their automobiles running smoothly, safely, and economically, potentially extending the lifespan of the car.

1. Fluid Checks

Monitoring fluid levels is a task easily accomplished at home. Although most modern cars incorporate sensors that alert you when fluids run low, with the vehicle’s longevity and well-being so dependent on various fluids, every car owner should carry out manual checks. Learning how to perform a periodic visual inspection can pay off in dividends, enabling you to quickly nip small issues in the bud before they become expensive, labor-intensive mechanical faults.

In terms of checking car fluids, engine oil tops the list. It is important to check not only that it reaches the proper fill level, but also that the oil is not discolored, contaminated, or burned. You should then check the coolant, measuring levels against the calibrations on the reservoir. Next, you should check your car’s brake and power steering fluids. Some vehicles allow you to check transmission fluid with a dipstick.

Finally, you should check your windshield washer fluid levels. Wiper fluid may seem like a trivial issue, but without it, you risk driving with a smeared or streaked windshield, which ultimately compromises safety. In addition, should the washer fluid pump dry out completely, it could leak or corrode. With some car models, if you turn on your wiper system without fluid, the system could fail.

You also need to maintain the correct balance of antifreeze versus wiper fluid appropriate for the climate you live in. Using plain water is a big no-no, since it can freeze across the windshield in cold weather, obscuring your vision completely.

2. Wheel Alignment

Wheel alignment affects how the car handles. It also impacts tread wear and the lifespan of tires and suspension components. Poor wheel alignment can be caused by a variety of different factors, including component wear, but the most common cause is hitting a pothole or curb, particularly at a high speed.

When the wheels are misaligned, you may notice a characteristic drag on the steering wheel, pulling the car to one side or the other. Poor wheel alignment not only causes premature and uneven tire wear, but it can also make the car dangerous to drive.

The wheels should be checked at least every 12 months to ensure they are properly aligned.

3. Replacing Wiper Blades

It is usually very obvious when wiper blades need changing. If they streak, the wiper blades need to be replaced.

Though there are many economy wiper blades on the market, it is often more economical in the long run to go with name brands, since these often incorporate UV protection and higher-quality rubber, increasing their lasting power. It is vital to retain a firm grip on the wiper arm after removing the old blade; otherwise, it could hit the windshield with sufficient force to crack it.

4. Power Steering Service

Without regular maintenance, a power steering problem rarely comes to light until it is too late. Over time, fluid within the power steering system becomes contaminated with moisture and dirt, clogging up components and eventually causing the system to fail.

The power steering’s function can be maintained by regularly topping up the power steering fluid. It is also helpful to periodically flush out the power steering system.

5. Differential Service

The differential transfers torque from the engine to the wheels. In some front-wheel drives, the differential is incorporated in the transmission, while others have separate units. In a rear-wheel drive, the differential is contained in the rear-end housing with the rear axles.

Over time, gear oil starts to degrade, diminishing its viscosity. This makes it less effective at lubricating the wheel bearings and differential. The transfer case should also be checked when the differential is serviced. Most car manufacturers set a maintenance schedule for checking fluids in both systems.

6. Air Conditioning Service

According to Murphy’s law, if the air conditioning system is going to break down, it will happen at the height of summer. A failed air conditioning system can make for a very uncomfortable ride.

The compressor contains oils to lubricate moving parts and seals. Since the air conditioning system generally only sees action in warm weather, these oils drain away from regions of the system that need them most. Switching on the air conditioning system for 15 minutes or so every month helps to circulate these vital oils, coating seals and helping moving parts to stay functional. Also, it is important to check refrigerant levels as part of the annual car maintenance service, looking for any leaks in the system, as well as topping up oil levels where necessary.
