- One Genuine GM oil fill cap assembly with seal.
The cap uses a molded grip for removal and a twist-on attachment to secure it at the oil filler opening. Its seal helps close the opening during normal engine operation.
The supplied cap is pictured with dexos, Mobil 1 and SAE 0W-40 markings. Use the vehicle owner’s manual to select the correct engine oil for the vehicle and operating conditions.
Replace a cap with cracked plastic, damaged locking features or a deteriorated seal. Oil residue near the filler opening should also prompt inspection of the cap, seal and filler neck.
- With the engine switched off and cool, clean loose dirt from around the filler opening before removing the old cap.
- Inspect the filler neck and sealing surface for damage or debris. Compare the replacement cap’s locking features and seal with the original.
- Install the replacement cap and turn it until properly seated, following the vehicle service guidance. Avoid forcing a cap that does not engage correctly.
- Check that the cap is secure after oil service. Use the owner’s manual for oil grade, quantity and oil-level checking instructions.
