Disconnect the cable from the negative terminal of the battery. Remove the dipstick and dipstick tube from the engine, noting that for 2009 and later models, this should be done after a specific step. For 2008 and earlier models, raise the vehicle and support it securely on jackstands, then remove the splash shield. For 2009 and later models, remove the coolant reservoir. Additionally, for 2009 and later models, remove the intake manifold, although for 2007 and 2008 models, it is not absolutely necessary but helpful for access to electrical connectors and the upper mounting bolt. Disconnect the oil pressure switch electrical connector. For 2008 and earlier models, detach the radiator hose holder from the starter bracket. Disconnect the electrical connectors from the "S" and "B" terminals. Remove the starter mounting bolts and guide the starter out. Replace the dipstick tube O-ring with a new one before installation. Installation is the reverse of removal, ensuring to tighten the starter mounting bolts. Finally, reconnect the battery.
