Steps
Raise the vehicle and drain the oil
Support the vehicle securely on stands and place a drain pan below the sump. Remove the drain plug, allow the oil to drain fully, then reinstall the plug.
Remove the old oil pan
Remove the pan fasteners and lower the pan carefully. If the seal is stuck, tap it with a soft mallet and pry only at designated points to avoid damaging the engine flange.
Clean the mating surfaces
Remove old sealant from the pan and engine with a plastic or suitable scraper. Keep debris out of the sump and clean both sealing surfaces so the new sealant can bond.
Seal and install the new pan
Apply the specified RTV bead in the correct path and set the pan in place. Start all bolts by hand, tighten them in the specified sequence and torque, and allow the sealant to cure as directed.
Replace the oil filter
Remove the old filter and clean its mounting face. Lubricate the replacement filter gasket with clean oil, install the filter, and tighten it according to its instructions.
Refill and check for leaks
After the sealant cure period, refill with the specified oil grade and amount. Start the engine briefly, inspect for leaks, shut it off, and recheck the dipstick level.
Check your vehicle’s repair manual for exact specifications and fit.
