What Happens When a Car’s Transmission Goes Out When a transmission “goes out,” the car may suddenly lose the ability to move, get stuck in a single gear, or refuse to shift—often accompanied by warning lights, harsh noises, or burning smells. In practical terms, the engine still runs, but power no longer reaches the wheels …
What Is the Clutch in a Car For? The clutch lets a driver temporarily disconnect the engine from the wheels to start, stop, and change gears smoothly; in short, it controls how and when engine power reaches the transmission. By engaging and disengaging the power flow—and allowing controlled slip—the clutch prevents stalling when pulling away, …
How a Car Clutch Works A car’s clutch is a friction-based device that temporarily disconnects the engine from the transmission so you can start, stop, and change gears; pressing the pedal releases spring pressure and separates the clutch disc from the flywheel, and releasing the pedal smoothly re-engages them to transmit power. In practice, that …

Expressways vs. Freeways: What Sets Them Apart The main difference is access control: freeways provide full access control with only grade-separated interchanges and no at-grade crossings, while expressways often have partial access control and may include some intersections, traffic signals, or direct property driveways. This distinction shapes safety, speed, and traffic flow, though terminology can …
Should You Connect Jumper Cables Directly to the Battery? Usually, you should not attach both jumper cable clamps directly to the dead battery. Connect the red (positive) clamp to the battery’s positive terminal or the vehicle’s designated positive jump post, and connect the black (negative) clamp to a solid, unpainted metal ground on the dead …
How Radiators Work for Cooling Radiators cool by moving heat from a hot liquid (coolant) into the surrounding air through thin tubes and metal fins, using conduction inside the radiator and forced convection to the air; a pump circulates the coolant, a thermostat regulates temperature, and fans or vehicle airflow carry the heat away. This …
Can I change my transmission fluid myself? Yes—on many vehicles you can change transmission fluid yourself with basic tools, the correct fluid, and careful attention to the manufacturer’s procedure. However, some modern transmissions require special tools, temperature-based level checks, or software steps that make a professional service the safer choice. Below, we explain how to …
Bad Idle Air Control (IAC) Valve: Symptoms, Causes, and What to Do A failing idle air control (IAC) valve typically causes rough or fluctuating idle, stalling at stops, hard starting (especially when cold), unusually high or low idle speed, surging when accessories are turned on, slow return to idle, and a check-engine light with codes …
How Often Should You Change Your Car’s Oil? For most modern cars using full-synthetic oil, plan an oil change every 7,500–10,000 miles or about once a year, whichever comes first; if your vehicle has an oil-life monitor, follow it. In harsher “severe-service” driving—frequent short trips, extreme temperatures, towing, dusty roads—aim closer to 5,000 miles or …
Is it worth getting full synthetic oil? Usually yes: full synthetic oil is worth it for most modern cars because it offers better protection in extreme temperatures, resists breakdown longer, and can safely support longer change intervals—especially if your owner’s manual specifies it. If you drive an older, gently used vehicle on short oil-change intervals, …
How Often Should You Change Your Car’s Oil? Most modern cars running full-synthetic oil need an oil change about every 7,500–10,000 miles or roughly once a year; older vehicles or those using conventional oil often require changes every 3,000–5,000 miles or about every six months.
