When Should Side Curtain Airbags Deploy? Side curtain airbags are engineered to deploy during moderate-to-severe side impacts and in rollovers—either detected or imminent—typically within about 12–20 milliseconds, and they often stay inflated longer (up to roughly 6 seconds) in rollovers to help prevent occupant ejection. They generally remain inactive in minor bumps, low-speed contacts, and …
How a Carburetor Works in a Small Engine A small-engine carburetor mixes gasoline with air using a venturi-driven pressure drop that pulls metered fuel through jets, while the throttle controls airflow, the choke enriches for cold starts, and dedicated idle and main circuits maintain the correct mixture from low speed to full power. In practice, …
Is a 1500 a Half-Ton Truck? Yes. In most U.S. pickup naming conventions, “1500” denotes a light-duty, full-size “half-ton” truck class (e.g., Chevrolet Silverado 1500, GMC Sierra 1500, Ram 1500). Ford uses “F-150” for the same class. The “half-ton” label is historical: modern 1500 trucks typically carry well over 1,000 pounds; always check the door-sticker …
How Long Does a Car Suspension Last? Most modern car suspensions don’t have a single “expiration date,” but you should expect major wear items like shocks and struts to last about 50,000–100,000 miles (80,000–160,000 km) or roughly 5–10 years. In harsh conditions—rough roads, heavy loads, extreme climates—key parts can tire out closer to 30,000–60,000 miles, …
