altenator

Instructions

1. • Disconnect the battery by turning the positive terminal bolt in a counterclockwise direction. The terminal can be set aside, as long as it does not touch the battery or vehicle frame.
   • 2Remove the radiator fan shroud, fan and radiator by turning their bolts counterclockwise and disconnecting the electrical connections. The coolant must be drained before removing the radiator by loosening the drain plug on the bottom left corner of the radiator frame. The hoses are held on with pinch-style hose clamps that can be gripped with a pair of pliers and slid back on the hose for removal. Once freed from the hoses, the radiator can be unbolted from the top mounts and slid out of the frame toward the top.
   • 3Uncouple the power steering pump hoses with a line wrench by turning the bolt in a counterclockwise direction. The hoses can be set aside. Some fluid may drain out into the drain pan.
   • 4Firmly press against the tension pulley to loosen the primary drive belt. This pulley is located on the right side of the engine as the Aurora uses a transverse-mounted motor.
   • 5Slide the primary drive belt off of the alternator pulley wheel and release the tension pulley. The belt will try to fall, as there is too much slack, but it can be propped up to retain its path through the other accessory pulleys.
   • 6Unbolt the alternator's two top bolts with a socket wrench. It may be necessary to use a universal joint socket because of the tight clearances.
   • 7Remove the alternator's third bolt from underneath the vehicle by turning it in a counterclockwise direction.
   • 8Disconnect the primary positive charging wire from the alternator's output terminal by loosening the nut in a counterclockwise direction.
   • 9Manipulate the alternator out of the engine compartment, taking care to not bump or harm any engine components in the process. The alternator can be worked out of the mount, then wiggled free toward the top of the motor.
   • 10Replace the alternator by positioning it into the mount, then securing the charging terminal by tightening the nut in a clockwise direction. Tighten the bottom mount bolt first, then the two top bolts to secure the alternator.
   • 11Replace the primary drive belt by pressing firmly on the tension pulley and sliding the belt onto the alternator's pulley wheel. It should seat into the grooves on the wheel and should become tight when the tension pulley is released.
   • 12Replace the power steering pump hoses and refill the power steering pump fluid to the proper level.
   • 13Replace the radiator, fan and fan shroud by securing the radiator into the frame and tightening its mount bolts. Connect the hoses and electrical fan connections. Refill the coolant system to the proper level.
   • 14Reconnect the battery's main positive terminal by turning the bolt in a clockwise direction.

Just the bulb or whole assemble??

should have a torx set screw on it, loosen it and use a flat screwdriver to pry button out of slot

I had the same problem and tried several things that didn't help. A friend introduced me to a Northstar mech. that explained the real problem. Internal engine relief was faling which created overheating between cylinder sleeves and engine block creating blow back pressure in cooling system. There is a fix for this. The mechanic helped me with the problem and car is running once more... Anyone thinking they have a head gasket, intake gasket, or thermostate problem should look at this fix.

You need to have the air ride system diagnosed& properly repairedThere is more to it,than just adding air to one or twoair shocks or struts,it is a complete system with aircompressor & various controls

There is most likely a problem with the tiny sensor in the ignition lock cylinder, it is not reading the key chip and locks u out, the problem is u can't just replace the lock cylinder u need a dealer only re-programm of the pass key system since the control module will not recognize the new lock code, catch 22 if u ask me. Do u have more than one key for the car? do both do this?

need the turn signal switch.

When the car reaches a preset temp the cooling fan is supposed to energize a realy the turns the cooling fan on....But if you turn the air on you basicly bypass the temp switch because you must have air moving at all times for the ac.. So now i would be looking for a defective temp switch or defective relay.....
