Things You'll Need
Wheel blocks
Bucket
Socket wrench
Clean rag
Solvent
Liquid gasket
Torque wrench
5 to 7 qt. of motor oil

Instructions
1
Park the GMC Sierra on a level surface and set the parking brake. Be sure to block the rear wheels to keep them from rolling.

2
Disconnect the battery cables and remove the oil dipstick, flywheel cover, oil cooler guides, front driveshaft. Unhook the exhaust pipes and remove the front engine mount bolts.

3
Put a bucket under the oil pan and remove the drain plug with a socket wrench. Let the oil drain into the bucket, and when it's finished draining, put the drain plug back on. Be sure not to overtighten the drain plug.

4
Loosen the oil pan bolts and take off the oil pan. Clean off the old gasket, making sure all traces have been removed. Wipe out the oil pan with a clean rag and clean the mating surface with solvent.

5
Apply a bead of liquid gasket to the mating surface and replace the oil pan while the liquid gasket is still wet. Torque the bolts according to specifications in the manual.

6
Reattach the engine mounting through nut and bolt, oil cooler guides and dipstick. Reconnect the exhaust pipe to the manifold, replace the flywheel cover and reconnect the battery cables.

7
Refill the engine with about 5 qt. of motor oil. Start the engine and then recheck the oil with a dipstick, adding enough oil to bring it to the full level. 2000 Jeep Cherokees require between 5 and 7 qt. of oil, depending on the size of the motor.
