Lost your oil cap? Is the old one cracked or not sealing right? This ACDelco FC232 Engine Oil Filler Cap is the real deal – it's a GM Original Equipment (OE) part. That means it's the exact same cap that was installed on your Chevrolet, Buick, GMC, or Cadillac vehicle when it rolled off the assembly line. The part number is FC232, which also crosses to 12621520. Why does that matter? Because an OE part is engineered to fit perfectly and seal properly, preventing oil leaks, keeping dirt out of your engine, and maintaining the correct crankcase pressure. Using a cheap, ill-fitting gas station cap can cause problems. This one is built to GM's specifications for durability and performance. It's a simple, small part, but it's super important for your engine's health. Installation takes two seconds – just twist it on. If you want to maintain your GM vehicle with the same quality parts it was built with, this is the oil cap to get. Don't risk engine issues with a generic cap; get the proper OE replacement from ACDelco. Keep your engine clean and running smoothly with the correct factory part.
