On 2008 and earlier models, open the fuel pressure release, disconnect the battery negative terminal, take out the intake duct connected to the air filter housing, disconnect accelerator and cruise control cables if installed, drain the cooling system and remove the Timing Belt/chain, Camshafts, temporarily install the valve cover, disconnect the camshaft position sensor, remove the complete fuel rail and injectors, take out the alternator and its mounting bracket, remove 2009 and later models need to do the following; relieve the fuel system pressure, join the negative battery terminal, lift the car properly with jackstands, drain the cooling system, remove the variable camshaft timing solenoid, remove the Timing Chain, put marks on the camshafts and bearing caps, remove the camshafts, remove the valve lifters and ensure that you mark them to facilitate reinstallation, remove the Intake Manifold, remove And starting from the last sequence with which the bolts were tightened, undo each of them by half a turn and while jacking up the cylinder head from the engine compartment be careful not to damage the aluminum alloy employed in its construction.
