Parts can range from $500–$1,800 (more for EPS), labor usually …
What Is Hydroplaning in Driving? Hydroplaning (also called aquaplaning) is when a vehicle’s tires ride up on a film of water and lose direct contact with the road, causing a sudden loss of steering, braking, and traction. It typically happens on wet roads—especially where water pools—and can occur at surprisingly low speeds depending on tire …
Are Hydrogen Cars Safer Than Electric Cars? In brief: neither hydrogen fuel cell vehicles (FCEVs) nor battery electric vehicles (BEVs) is categorically “safer” than the other; both can meet high safety standards, but their risk profiles differ. BEVs primarily contend with battery thermal runaway and high-voltage hazards, while FCEVs manage high‑pressure hydrogen leaks and fires. …

How to Turn On Your Windshield Wipers Most cars use a stalk on or near the steering column to control the wipers: rotate a ring or move the stalk up/down for mist, intermittent/auto, low, and high; pull or push the stalk to spray washer fluid. Some vehicles use a dashboard knob or a touchscreen button. …
How Traffic Lights Know You’re There Most modern traffic lights detect your presence using sensors—most commonly inductive loops embedded in the pavement, along with video cameras, radar, or magnetometers—not your vehicle’s weight. These sensors inform a signal controller that you’re waiting, which then schedules or extends a green light based on demand, timing plans, and …
3.73 vs 4.10 Axle Ratios: Which Is Better? It depends on how you use the vehicle. A 4.10 axle ratio delivers roughly 10% more wheel torque than a 3.73, improving acceleration, towing, and off‑road control, but it raises highway RPM by about 150–250 rpm at 70 mph and can trim fuel economy. A 3.73 is …
Power Brakes vs. “Normal” Brakes: What’s the Difference? Power brakes use an assist device (vacuum, hydraulic, or electric) to amplify the force you apply on the pedal, while “normal” brakes—properly called manual or non-assisted brakes—rely solely on your leg strength. Both can stop a vehicle effectively when designed correctly, but power brakes require far less …
How Air Brakes Work, Simply Explained Air brakes use compressed air stored in tanks to apply braking force: pressing the pedal opens valves that send air to brake chambers at the wheels, where diaphragms push rods to press brake pads or shoes against rotors or drums; releasing the pedal vents air so return springs release …
What Is the Most Famous Lowrider Car? The 1964 Chevrolet Impala is widely regarded as the most famous lowrider car; among individual, named builds, the pink, rose-painted “Gypsy Rose” (a 1974 Chevrolet Monte Carlo) is the single most iconic. This distinction reflects both a model that became the lowrider community’s flagship and a specific car …
Is supercharging a car illegal? Generally, adding a supercharger to a car is not illegal by itself; it becomes unlawful if the modification violates emissions, noise, safety, or registration rules, or if you fail to disclose it to your insurer. In electric-vehicle contexts, “supercharging” at a rapid-charging station (such as Tesla Superchargers) is legal when …
Is NOS Good for Your Car? Often yes for short, controlled bursts of power—if your engine, fuel system, and tune are prepared—but it can quickly become harmful, illegal to use on public roads in many places, and expensive if installed or operated incorrectly. This article explains what “NOS” really is, how it works, the benefits …
Highway vs. Freeway: What’s the Real Difference? A highway is any public road, while a freeway is a specific type of highway built for high-speed, uninterrupted travel with full control of access and no at-grade crossings. Put simply: all freeways are highways, but not all highways are freeways. The distinction matters for safety, speed, access, …
What Is the Most Modern Car Today? The most accurate answer is that there isn’t a universally agreed “most modern car,” because different models lead on different fronts; however, if one vehicle currently makes the strongest single-vehicle case on legally approved autonomy, software sophistication, and integrated safety redundancy, it’s the 2024–2025 Mercedes‑Benz EQS with Drive …
No Gas Cap? Safe Options, What to Avoid, and How to Get Back on the Road If you don’t have a gas cap, the safest move is to buy the correct replacement immediately; for a short drive, most cars can be driven without a cap as long as you close the fuel door, and if …

Can You Drive With a Bad Muffler? You can usually drive a short distance with a bad muffler, but it’s not advisable: it can be illegal due to noise or emissions rules, it poses safety risks from exhaust fumes and loose parts, and it can lead to more expensive repairs if ignored. A failing muffler …
How a Radiator Works, Step by Step A radiator moves heat from a hot fluid to cooler air by pushing that fluid through thin, finned tubes where air carries the heat away (in cars) or draws the heat into a room (in buildings). In practice, pumps move fluid, thermostats regulate temperature, and fins increase surface …
What is the purpose of pretensioners? Pretensioners are safety devices in vehicle seat belts that rapidly tighten the belt at the first sign of a crash, removing slack to position occupants correctly and reduce forward movement. By cinching the belt moments before or at impact, they work with airbags and load limiters to lower injury …
How to Tell If Your Torque Converter Clutch (TCC) Solenoid Is Bad If your torque converter clutch solenoid is failing, you’ll typically see a check-engine light with codes like P0740–P0744, feel shudder or “chatter” at steady cruise, experience stalling when coming to a stop, and notice that the TCC never locks in live data even …
Turbo vs. Supercharger: Which Is Better for a V8? For most V8 builds, neither is universally “better”: choose a supercharger if you want instant torque, linear response, and simpler packaging; choose a turbo (often twin-turbo) if you want the best power-per-pound, altitude compensation, and better efficiency potential at cruise. The right answer depends on how …
Are 4×4 and 4WD the same? They’re often used interchangeably to describe vehicles that can drive all four wheels, but they’re not perfectly identical terms: “4×4” describes a vehicle with four wheels, all four driven; “4WD” (four-wheel drive) refers to the drivetrain system that powers all four wheels. On most passenger vehicles with four wheels, …
How Long Does a 30K Car Service Take? Most 30,000‑mile (≈48,000 km) services take about 1.5 to 3 hours for a typical gasoline car if only the routine items are due; expect 2 to 4 hours if fluid flushes or extra replacements are added. For many EVs, the visit can be 45 to 90 minutes. …
Spark Plug vs. Ignition Coil: What’s the Difference? No. A spark plug is not the same as an ignition coil. The ignition coil turns the car’s 12-volt power into tens of thousands of volts, while the spark plug uses that high voltage to create a spark that ignites the air–fuel mixture in the engine. They …
What types of lowriders are there?
