Corteco 12019250B Crankshaft Shaft Seal

Description

The Corteco 12019250B is a crankshaft shaft seal, crucial for preventing oil leaks and maintaining proper lubrication within the engine. This seal is typically located around the crankshaft where it exits the engine block, ensuring a tight barrier between the engine's internal oil supply and the external environment. Measuring 12 x 54 x 54 mm and manufactured in Turkey, this component helps extend engine life and optimize performance by minimizing friction and wear, thus contributing to increased efficiency and reliability.

Key Features & Benefits

This seal basically keeps oil in and keeps dirt and debris out. It sits right where the crankshaft comes out of the engine block. The crankshaft is what’s turning everything, and it’s bathed in oil for lubrication. This seal’s job is to contain that oil so it doesn’t leak all over the place, and it prevents things from the outside – dust, water, road grime – from getting inside the engine where they don’t belong. It’s a pretty simple part, but critical. Think of it as a barrier protecting the heart of your engine. It’s positioned between the rotating crankshaft and the stationary engine block. As the crankshaft spins, the seal has to move with it, maintaining that tight barrier. It’s part of the engine’s sealing system, alongside things like your valve cover gaskets and oil pan gasket, but this one has a particularly tough job because of that constant rotation.

Symptoms, Risks & Replacements

If this seal fails, you’ll start to see oil leaks. At first it might just be a small drip, but it can quickly become a significant leak. Lost oil means less lubrication for your engine, which can lead to major damage – worn bearings, a scored crankshaft, even engine failure. You’ll notice if it’s leaking – usually a smell of burning oil, or a visible puddle under your car. Replacing it is a relatively inexpensive fix compared to the cost of repairing engine damage. You can find a good replacement at places like Fixparts Online, and there are lots of helpful videos online showing you how to install it yourself if you’re comfortable doing that sort of thing. It acts like a shield, really – protecting a very expensive component.
