GMC 14082348 Pan,Oil

As a rule, it is not required to lift the engine, which makes this process rather easy. First you should check the state of the pan clearance and then remove the negative terminal of the battery. Lift the car and place it on jack stands then proceed to drain the engine oil into an oil pail. If so, unbolt the automatic transmission flex plate lower cover and, also, perform removal of the exhaust crossover pipe at the manifolds. Then, take out all the oil pan attaching bolts and then detach the oil pan from the vehicle. The pan should then be well washed with the right solvent; the gasket contact surfaces, on the face of the block and the pan, should be free from dirt, rough or containing previous deposits of the gasket. Some sealer should be applied in a few places on the new oil pan gasket, then it can be put in position on the pan, the bolt holes should match. Last of all, fit in the oil pan along with the pan bolts and tighten them by applying a torque based on manufacturer's guidelines.

If the engine has been removed from the car, most of the above steps will not be required, and the pan can be simply unbolted and removed from the engine block, with installation following the previously mentioned cleaning and sealing procedures.

For manual transmissions, disconnect the clutch cordon shaft; for automatics, disconnect the cooler lines, detent cable rod or switch wire, and modulator line.

Apply sealer to the new oil pan gasket in several places and install it on the pan, making certain that the bolt holes line up.

Lower the engine onto the mounts and install the throughbolts.

Remove the oil pan bolts and separate the oil pan from the block.
