Disconnect the cable from the negative battery terminal. On models where it visibly prevents access to the alternator, remove the air filter housing and intake tube. Loosen the right-front wheel lug nuts, raise the vehicle and support it securely on jackstands, then remove the right-front wheel. Remove the right-front fenderwell splash shielding. Remove the accessory drivebelt. On 2007 and earlier 2.0L models, remove the supercharger for access to the alternator. Unscrew the terminal nut(s) and disconnect the electrical connections from the alternator, noting the correct terminal locations for installation. If you cannot easily access the electrical connections at this time, wait until the alternator has been unbolted and repositioned, then disconnect the electrical connections. If equipped, unbolt and remove the engine hoist eyelet bracket located above the alternator. On HHR models, remove the radiator upper support brackets to allow the radiator/condenser assembly to be tilted slightly forward for additional clearance. Remove the 3 alternator mounting bolts, then carefully guide it out of the top of the engine compartment. If the alternator still doesn't have enough room for removal, it may be necessary to unbolt and disconnect the windshield washer reservoir and fluid lines/washer pump electrical connector (HHR models), then, while supporting the engine using a floor jack and block of wood placed evenly under the engine oil pan, remove the right-side engine mount. Raise or lower the engine slightly to allow for better clearance to remove the alternator. Installation is the reverse of removal. Tighten the alternator mounting bolts, and all other fasteners, where mentioned. Whenever the battery has been disconnected, the PCM must relearn its former drivability and performance characteristics.
