Genuine GMC OEM 10W-30 Engine Oil Filler Cap With Seal - Part #12589430, Direct Replacement

About This Product

Hey there, if you're looking for a solid replacement oil filler cap for your GMC, this is the real deal! It's a genuine OEM part straight from General Motors, part number 12589430 (also known as ACDelco FC219 SAE 10W-30). This little guy comes with a fresh O-ring seal already installed, so you don't have to mess around buying it separately. It's made from sturdy black plastic with a painted finish, and it's designed as a direct replacement—meaning it should twist right on like your old one did. The seller notes it's brand new but might come in bulk packaging, so there could be some minor scratches from storage (nothing that affects how it works, though!). Fits where you need it, no universal fit here. Other part numbers that match include 21007373, 24100010, and a few others. No manufacturer warranty listed, but it's an OEM cap so you're getting factory quality. Perfect for a quick maintenance fix or if you lost your original cap. Keep your engine sealed up tight and avoid leaks with this simple upgrade!
