You can Select Your Vehicle to check if 14081203 fits your vehicle.

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.

In most cases, the engine will not need to be raised, which will greatly ease the procedure, so inspect the pan clearance before beginning. Start by disconnecting the negative battery cable, then raise the car and support it firmly on jack stands. Drain the engine oil into a suitable container and remove the automatic transmission flex plate lower cover if equipped. Disconnect the exhaust crossover pipe at the manifolds, then remove the oil pan attaching bolts and take off the oil pan. Clean the pan thoroughly with the proper solvent, ensuring that the gasket surfaces on the block and pan are clean, smooth, and free of old gasket material. 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. Finally, install the oil pan and pan bolts, torque-tightening the bolts to specifications.

Remove the oil dipstick and dipstick tube.

Lower the engine onto its mounts, install the through bolts, and tighten them to the specified torque, then add the correct grade of oil to the engine and check for leaks.
