How to put in 2003 chevy calvlier alternator my self
1) Open driver's door window (in case the car auto-locks shut), remove keys from car's interior, and disconnect the vehicle's battery's negative terminal wire and tuck it away, making sure it cannot touch the battery negative terminal (you might wrap it in a cloth, just to make absolutely sure) (make sure you have any stereo security codes, before disconnecting this). Also make sure you have any alarm system turned off, or have the key to do so.
2) Remove the alternator drive belt. Serpentine belt types require a spring tensioned pulley to be forced against spring pressure, away from the belt in order to remove the belt (MAKE SURE you take careful note of this belt's route for easy refit. Take a photo if necessary!). Traditional tensioners require a locking bolt to be slackened and then an adjustment bolt to be slackened, plus affixing bolt to be slackened in order to freely remove the belt.
3) Disconnect the wires from the back of the alternator unit. You may typically have one plug connector and one or two heavy duty wires on the back.
4) Remove any remaining alternator fixing bolts which are keeping it affixed to the engine block, and remove alternator.
1) Locate alternator position and lightly screw in all affixing bolts (do not tighten if using traditional type, manual tensioner). Tighten if using a serpentine belt tensioner (spring loaded type).
2) Re-attach all wiring and check for tight connections.
3) Replace drive belt. If using traditional tensioner, then manually adjust the belt tension so that you can twist the belt to about 90 degrees when tight, no further.
4) Clear the engine bay of all tools, reconnect vehicle battery negative lead.
5) Restart vehicle.
6) Listen for belt squeal (may need tightening further if manually adjusted). Take note of dashboard charge warning indicator. If illuminated, then check battery connections and alternator connections.
7) If you have a multimeter, then check voltage across battery terminals with vehicle running. Voltage should measure around 14Volts with a healthy alternator fitted.
8) After running for a few minutes, stop engine and recheck belt tension if using a manual tensioner. BE CAREFUL of any hot areas as these may burn. If in doubt, then wait until the engine is cold and re-adjust if necessary.
