It has a rubber sealing ring that keeps the engine oil and crankcase vapors in, while keeping water and dirt out. This original equipment engine oil filler cap has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Replaced old one and glad I did. The old one’s rubber ring seems to have shrunk and deteriorated a little after five years. I did this because I recently learned that you should replace the radiator cap every 50,000 miles or so, to keep the system’s pressure correct. I haven’t researched it yet but figured it would be wise to also change the oil filler cap and brake fluid cap too. This new one looks much better than the one I replaced with 67,000 miles. The rubber seal looks much better and it seems like a good way to make sure that contaminants don’t get into the engine block. It’s worth the peace of mind knowing I’m doing what I can to keep things clean and running smoothly. Fast shipping. Correct part. Fits perfectly.

Ok so if I hadn't forgot to put it back on I wouldn't have needed to order one. But lesson learned it first great and I'm happy with my purchase.

How does one lose the oil cap on your engine??? IDK, ask my son. Lets see, what can be said about this product? Its OEM, it fit right on the motor where the old cap used to sit and it and its doing an AMAZING JOB of keeping the oil IN the motor and dirt OUT of the motor.
