- Remove the old gasket and thoroughly clean both the engine block and oil pump mating surfaces. Ensure they are free of old gasket material, oil, and debris.
- Position the new gasket correctly on the engine block; its shape should prevent misalignment.

- Refill the engine with the correct grade and amount of oil, and install a new oil filter.
- Reconnect the battery, start the engine, and check carefully for any oil leaks around the pump.
Troubleshooting & FAQ
How do I know if my oil pump gasket is failing?
Signs of a failing oil pump gasket include visible oil leaks from the area where the oil pump meets the engine block, a low oil pressure warning light on your dashboard, or an engine that is running hotter than usual.
Is this gasket compatible with engines not on the compatibility list?
While it may fit other models, we only guarantee compatibility for the engines listed. To prevent leaks and ensure proper function, please verify that your old gasket's design and bolt pattern match the images and specifications before purchasing.
Do I need to apply sealant to this gasket during installation?
This gasket is typically designed for a "dry fit" without any additional sealant. However, always refer to your engine's official service manual for the most accurate, model-specific instructions regarding the use of sealants.
What is the recommended replacement interval for an oil pump gasket?
An oil pump gasket does not have a scheduled replacement interval. It should be replaced anytime the oil pump is removed for service or as soon as a leak is detected to prevent oil loss and potential engine damage.
