These things basically store mechanical energy. Think of it like winding up a toy—you’re storing power in that little spring inside. In an engine, they do that with movement. They come in a lot of different sizes and strengths depending on what they're controlling. You'll find them on valves, in starters, sometimes even holding tension on belts. They’re all about controlling motion and returning things to a specific position. They’re pretty widespread actually. The most common ones people think of are valve springs. Those control when the engine's valves open and close, letting air and fuel in and exhaust out. Other springs might be in your starter, helping it engage and disengage the engine to get things going. You’ll even find them in things like timing chains to keep tension right. They’re usually small parts, but they affect a lot of bigger systems. A failing spring can cause a whole heap of trouble. If a valve spring breaks or loses tension, you’ll notice if your engine misfires, loses power, or runs really rough. A weak starter spring can lead to a slow crank or even a starter that doesn’t engage at all. Sometimes it’s a gradual thing, and sometimes it’s a sudden failure. A spring doesn't necessarily cause a major problem, but it’s usually a sign that something else is stressed or failing. They act like a shield in a way – when they go, it often means whatever they're protecting is about to follow. We carry a good selection of these at Fixparts Online, and it’s always smart to replace them when you’re doing other engine work, just to avoid headaches down the road. More than just a part: Spring (MPN 030109623J) includes a 12-month warranty!
