How to Replace Oil Pan 2006-2012 Nissan Altima

Difficulty: Advanced · About 150 min · Nissan Altima

Replace the oil pan on a 2006–2012 Nissan Altima and allow the specified sealant to cure before refilling the engine.

Steps

1. Raise the vehicle and drain the oil

   Chock the wheels, raise the vehicle at approved points, and support it securely on jack stands. Remove the oil fill cap and dipstick, place a drain pan beneath the pan, remove the drain plug, and let the oil drain fully.

2. Remove the old oil pan

   Remove the pan fasteners, leaving two opposite bolts loosely installed until the seal breaks. Tap the pan with a soft mallet or use a designated pry point, then remove the remaining bolts and lower the pan carefully.

3. Prepare the sealing surfaces

   Scrape old sealant from both mating surfaces without gouging the aluminum, then clean and dry them completely. Keep debris out of the engine and check the pan flange for distortion before applying fresh sealant.

4. Install the pan and sealant

   Apply a continuous bead of the specified gasket maker in the required path, then position the pan promptly. Start all bolts by hand and tighten them in the correct sequence and to the vehicle specification; allow the sealant to cure for its stated time before adding oil.

5. Refill oil and check for leaks

   Install a new oil filter with its gasket lightly oiled, lower the vehicle after the sealant cure period, and fill with the manual-specified oil. Start the engine briefly, inspect the pan and filter for leaks, shut it off, and verify the dipstick level.

Check your vehicle’s repair manual for exact specifications and fit.
