This bolt secures one of your crankshaft bearings. That bearing lets the crankshaft spin smoothly, and this bolt keeps everything clamped down tight so it doesn't move. It’s a fastening component, pure and simple, but it’s doing a really important job holding everything together. Think of your engine like a really complex machine with lots of moving parts. The crankshaft is a major one, turning back and forth to make the car go. This bolt, along with a few others, acts like a shield, preventing vibration and keeping that crankshaft aligned. It’s part of the overall structure that allows the engine to transfer power effectively. It's not directly making the car move, but without it, nothing else will work right. If this bolt fails, or even gets loose, things can go downhill fast. You'll notice if it’s failing because you’ll likely hear knocking sounds from the engine, especially under load. Over time, a loose bolt can allow the bearing to move, leading to wear and damage to the crankshaft itself. That’s a costly repair – way more expensive than a simple bolt! It’s a small part, but it prevents a much bigger problem. You can find replacements pretty easily, places like Fixparts Online have them in stock, and it’s something you’d want to address right away if you suspect a problem. Shop with confidence: Bolt (MPN N90365801) comes with a 12-month warranty!
