How much oil does a 2.0 L engine take?

The exact capacity depends on the specific engine family, …
Three Signs Your Cabin Air Filter Is Clogged The three most common symptoms of a clogged cabin air filter are weak airflow from the vents, a persistent musty or unpleasant odor in the cabin, and windows that fog up more easily with poor defog/defrost performance. These issues arise because a clogged filter restricts air movement …
Is It Worth Replacing a Car Radiator? Yes—if your radiator is leaking, clogged, or structurally damaged, replacing it is usually worth it because overheating can destroy an engine and transmission, leading to repairs far costlier than a new radiator. In other situations—like a bad cap, failing fan, or minor hose leak—targeted fixes can restore cooling …
Can I use a 28-inch wiper instead of a 26-inch? Usually, no—stick with the manufacturer’s recommended size. A 28-inch blade in place of a 26-inch often extends too far and can strike the windshield trim, the hood, the A-pillar, or even the opposite wiper. It may work on some vehicles with ample clearance, but you …
Is 4 mm OK on brake pads? Yes—with caveats. On passenger cars and light trucks, 4 mm of remaining friction material is generally safe for short-term driving but is close to the typical replacement threshold, so you should plan a brake job soon. On motorcycles, 4 mm is usually serviceable and often mid-life. On bicycles, …
Is It Worth Touching Up Car Paint? Yes—touching up small chips and light scratches is usually worth it to halt rust, keep the car looking presentable, and protect resale value at low cost. It’s not worth it for larger or numerous defects where a professional repaint will blend better and last longer. Here’s how to …
Is It Worth Fixing an AC Compressor in a Car? Often yes—if you plan to keep the car for several years and the vehicle is otherwise in good shape, repairing or replacing a failed AC compressor is typically worth it.

Is It Worth Replacing a Car AC Compressor? Usually yes—if you plan to keep the car for a few years, the rest of the AC system is healthy, and the total bill is a reasonable share of the vehicle’s value. It’s often not worth it when the car is near end-of-life, the system is contaminated, …

If you’re replacing pads on both axles (eight pads …
Are H7 and H11 the same bulb? No. H7 and H11 are different automotive headlight bulb types with distinct bases, connectors, and mounting systems, so they are not interchangeable. Both are single-beam 12V halogen categories often used for low or high beams (and fog lights in the case of H11), but their physical fit, electrical …
Are 9004 and 9005 Bulbs the Same? No. 9004 and 9005 headlight bulbs are different in design, socket, and function, and they are not interchangeable. The 9004 (HB1) is a dual‑filament bulb for combined low/high beams, while the 9005 (HB3) is a single‑filament bulb typically used for high beams only. Mixing them can lead to …

Used incorrectly, though, it can trap moisture, scuff paint, or flap in the wind and cause damage. The decision …
