Common car problems and how to fix them
Car ownership can be a challenging experience due to the myriad of issues that can arise unexpectedly. While many of these problems have straightforward solutions, identifying them can often be a daunting task. Here, we aim to help car owners navigate through some common issues, and provide effective strategies to fix them.
Dealing with unusual engine noises
Unusual engine noises can be a cause for concern for car owners. These sounds could indicate a variety of problems, from loose components to oil pressure issues. If the oil level is not within the recommended range, metal parts may rub against each other, causing these noises. A decrease in power or engine misfires following the rattling sound could suggest a problem with the timing belt. Loose exhaust components are also known to cause rattling within the engine bay.
Fixing a broken air-conditioner
Turned on the air conditioning only to feel the same old room-temperature air? It's likely your car's A/C system is having issues. Check if the refrigerant level is low—it could mean there's a leak somewhere. You can top up the refrigerant yourself, but if you're unsure, it's best to consult a professional or mechanic.
Addressing issues with soft or spongy brake pedals
Issues with braking system, like softer-than-usual feel or excessive pedal travel, require immediate attention. These symptoms could be due to air pockets in brake lines, leaking disk calipers, or leaking wheel cylinders. Air in brake lines can disrupt fluid flow and make the pedal feel soft. This can be resolved by flushing the fluid. Corroded disk calipers may cause piston seal to leak brake fluid. If brakes pull to one side, it might indicate reduced fluid pressure at one caliper.
Identifying a malfunctioning alternator
The alternator—crucial component connecting the battery to the engine—can cause various symptoms if it malfunctions. These include a dead battery, faulty electronics, and unusual smells. To determine whether the issue lies with the battery or alternator, car owners can jump-start their vehicle and observe its behavior. If the engine dies shortly after removing jumper cables, this could indicate an inefficient alternator unable to properly charge the battery. A burning rubber or wire smell may suggest worn-out parts of the alternator.
Managing engine stalling post-battery replacement
Modern cars operate on complex computers that need a consistent power supply to function and maintain settings. When replacing a battery, the power flow to the computer is interrupted, causing it to lose VRAM settings and revert to default ones. These default settings may not be suitable for an aging car, leading to potential engine stalling. To help the car relearn its settings, owners should start it on level ground and let it idle with all unnecessary electronics switched off.
