The Positive Crankcase Ventilation (PCV) valve prevents vapors from leaking from your 2007 Jeep Libertys engine into the atmosphere. The PCV valve forces harmful vapors back into the combustion chambers, so that they burn off during the fuel combustion cycle. When your Libertys "check engine" light comes on, or when your vehicle fails an emissions test, the PCV valve most likely has failed. Buy a replacement valve from an auto parts store.
Instructions
1 Raise the hood of your Liberty and rest it on the prop rod. Locate the PCV valve protruding from the back of the left cylinder head.
2 Pull the rubber hose straight back off the end of the PCV valve. Unscrew the PCV valve from the mounting area, by hand. Discard the old valve. Thread the replacement PCV valve into the mounting area, by hand, until it is secure.
3 Push the rubber hose back onto the end of the new valve. Push the hose back until it stops, making sure it is tight. Close the hood of the Liberty.

You can reset the change oil message on your 2008 Jeep Liberty right in your garage, saving time and money. The Liberty keeps track of your oil changes and alerts you to when the next one is due. A light illuminates on the instrument panel to alert you to the need for an oil change. Usually your mechanic will reset the light, but not always. If you change the oil change yourself, you will need to know how to reset it.
Instructions
1 Put the key in the ignition and turn it to the "On" position, but dont start the engine.
2 Press the accelerator to the floor very slowly three times within ten seconds. Turn off the ignition.
3 Turn the key in the ignition to the "On" position again. The "Change Oil" light should now be off. If its still illuminated, repeat the above procedure.

The Jeep Liberty is a compact sport utility vehicle manufactured by Chrysler under its Jeep marque. The 2004 model has a choice of several different engines, such as a 4-cylinder, 2.4-liter engine. The oil pump for this engine is attached to the bottom of the engine block above the oil pan. The replacement of the oil pump also requires the removal of several other components to access the oil pump.
Instructions
1 Disconnect the cable to the negative battery terminal with a socket wrench. This prevents you from starting the engine while replacing the oil pump. Remove the mounting bolts for the the timing belt cover and detach the timing belt cover. Disconnect the timing belt from its pulley. Remove the oil pan mounting bolts and disconnect the oil pan.
2 Remove the crankshaft sprocket with tools 6793 and C-4685-C2. Disconnect the crankshaft key with a socket wrench and detach the oil pickup tube from the oil pump. Remove the mounting bolts for the oil pump. Disconnect the oil pump and remove the front crankshaft seal.
3 Clean the mounting surfaces for the oil pump with a shop rag. Apply gasket sealer to the new oil pumps mounting surface and install the new gasket onto the oil pump. Align the rotor flats of the oil pump with the rotor flats on the crankshaft. Connect the oil pump to the engine block with a socket wrench.
4 Install a new front crankshaft seal and connect the crankshaft key. Install the crankshaft sprocket with tool 6792 to ensure that you set the sprocket to the correct depth. The camshaft sprocket can damage your timing belt and engine if you do not install it correctly.
5 Attach the pickup tube to the oil pump. Connect the oil pan to the engine block with a socket wrench and install the timing belt. Replace the timing belt rear cover and connect the cable to the negative battery terminal.
