You can Select Your Vehicle to check if YF1Z-6268-AA fits your vehicle.

To remove the timing cover for 2008 and earlier models, disconnect the negative battery cable, remove the drive belt and tensioner, disconnect the crankshaft position sensor electrical connector, and move the wiring harness away from the engine cover. Remove the crankshaft position sensor, crankshaft pulley, water pump pulley, and the electrical connector to the power steering pressure switch. Move the power steering pump aside after removing its bolt, then remove the bolts securing the engine cover. For 2009 and later models, raise the vehicle and support it on jackstands, disconnect the negative battery terminal, remove the drive belt and idler pulley, and then the crankshaft pulley. Support the engine with a floor jack, remove the front engine oil seal, water pump pulley, drive belt idler pulley and bracket, and the crankshaft position sensor. Loosen the front cover bolts evenly and tap the cover sideways if necessary before removal. For installation, clean the mating surfaces, install the engine cover within four minutes of applying a 2.5 mm bead of RTV sealant, tighten all bolts to specified torque settings, and ensure to re-time the engine using a new crankshaft position sensor with the necessary alignment tool. To remove the timing chain and tensioner, apply the parking brake, jack up the front of the vehicle, and support it on jackstands. Remove the timing cover, compress the timing chain tensioner, and place a pin to hold it in the compressed position. If the ratchet mechanism needs resetting, remove the tensioner, relieve the tension on the ratchet, and then reinstall the tensioner. Remove the tensioner mounting bolts, the loose timing chain guide, and the timing chain. If necessary, the left chain guide and camshaft sprockets can be removed. For installation, remove the camshaft alignment tool if installed, loosen the camshaft sprocket bolts without removing them, and install the left chain guide, timing chain, and right chain guide. Install the timing chain tensioner, tighten the fasteners, and remove the pin to engage the chain guide. Reinstall the camshaft alignment tool and tighten the camshaft sprocket bolts while holding the camshafts in place. Finally, install the timing cover.

The pulse (trigger) wheel has slots for more than one engine. Note the exact position of the pulse wheel to ensure correct reassembly. On 3.0L engines, the slot marked in orange and stamped "30 RFF" must align over the crankshaft/pulley key.

Raise the vehicle and support it securely on jackstands.

Mark all parts that will be reused to ensure they can be reinstalled in their original locations.

The procedure is very difficult due to a lack of clearance. It may be easier to remove the engine from the vehicle if major engine work is being performed.

Remove the bolts and the timing cover.
