How to Change the Oil Pan in a Chevrolet K2500

by Robert Good

The Chevy K2500 is a 4x4 truck with an optional gas or diesel engine. The "K" in K2500 indicates four-wheel drive. The oil pan on this truck is on the bottom of the engine in the center. It is secured to the engine block with bolts around the edge of the oil pan. The number of bolts, size and torque specifications depend on the type of engine.

Step 1

Lift the front left side of the Chevy K2500 using your jack. Lower the front end on the jack stand. Place the oil catch pan under the drain nut on the bottom of the oil pan.

Step 2

Remove the drain nut using a ratchet set. Drain the oil from the oil pan. Replace the drain nut. Remove the oil catch pan from under the truck.

Step 3

Remove the bolts from around the edge of the oil pan in an X pattern, using a ratchet and socket. After all the bolts have been removed tap the sides of the oil pan with a rubber hammer until the oil pan comes off the engine block.

Step 4

Place the new oil pan gasket onto the edge of the new oil pan. Place the new oil pan on the bottom of the engine block. Insert the mounting bolts into the holes around the edge of the engine oil pan.

Tighten the mounting bolts to the torque specification for the specific engine model, using a torque wrench in an X pattern. Lower the truck to the ground.

Tip

  • Place new paper under the engine before you pull the oil pan off the engine block. Oil will leak from the engine block as soon as you remove the oil pan.
