Yes, a check engine light (CEL) can cause a vehicle to fail an emissions inspection. The check engine light indicates that the vehicle’s onboard diagnostic system has detected a problem with the engine, emissions system, or other critical components. Since the light signals potential issues that could affect emissions, most states require it to be…
Installing a catch can on your vehicle typically does not void your warranty—at least not automatically. However, if the catch can causes damage to your engine or is proven to be the reason for a failure, the manufacturer could deny warranty coverage for those specific repairs. Understanding how a catch can works, how it’s viewed…
Yes, certain types of car batteries, specifically lead-acid batteries, do need water to function properly. Water plays a crucial role in the chemical reaction inside these batteries. If the water level gets too low, it can lead to decreased performance, shorter battery life, and even permanent damage. However, not all car batteries require water maintenance….
Yes, a car battery can charge while the engine is idling. As long as the engine is running, the alternator produces electrical power and recharges the battery. However, the efficiency and speed of charging at idle are lower compared to when the vehicle is driving at higher speeds. Understanding how battery charging works when idling…
Yes, a car air conditioner (AC) uses gas, but not in the way you might think. The air conditioning system in your vehicle doesn’t use gasoline directly to cool the cabin. Instead, it relies on refrigerant gas to transfer heat from the interior of the vehicle to the outside. The air conditioner system works by…
Yes, a bug deflector really works, but how well it performs depends on factors like the design, vehicle type, and driving conditions. Bug deflectors, also known as hood deflectors or bug shields, are designed to alter the airflow over your vehicle to reduce the number of bugs, small debris, and rocks that hit your windshield…
Yes, a blown head gasket can make noise, but the noise is typically not the first symptom you’ll notice. A blown head gasket is a serious engine problem that can lead to a variety of issues, including unusual sounds. These noises often occur due to the pressure buildup in the engine or coolant and air…
Yes, a bad wheel bearing almost always makes noise. One of the most common symptoms of a failing wheel bearing is an unusual sound coming from the wheels or suspension area. This noise can start out subtle and get louder over time as the damage worsens. Recognizing these noises early can help prevent more serious…
Yes, a bad catalytic converter can affect gas mileage. The catalytic converter plays an important role in your car’s exhaust system, helping to reduce harmful emissions. But when it starts failing or becomes clogged, it can directly impact engine performance and fuel efficiency. Let’s explore how a faulty catalytic converter can lead to reduced gas…
Yes, a bad catalytic converter can produce a noticeable and unpleasant smell. One of the most common signs of a failing catalytic converter is a strong sulfur or rotten egg odor coming from the exhaust. This smell often indicates that the catalytic converter is no longer effectively processing exhaust gases. Understanding why a bad catalytic…
