Steps
Drain the engine oil
Warm the engine briefly, turn it off, then raise the vehicle at approved points and support it securely. Place a pan below the plug, remove it, and let the oil drain.
Remove the used filter
Loosen the old filter with a filter wrench, keeping the pan underneath. Clean its mounting surface and confirm the old gasket came off with the filter.
Install the new filter
Apply a thin film of fresh oil to the new gasket and install the filter by hand as directed. Avoid using a wrench to overtighten it.
Refill and verify
Tighten the drain plug to vehicle specification, lower the vehicle, and add the specified oil quantity. Start briefly, inspect for leaks, then check and adjust the dipstick level.
Check your vehicle’s repair manual for exact specifications and fit.
