How can i reset {turn off} the check engine light?

1995-98 Models

1. Disconnect the negative battery terminal.
2. Remove the splash guard on the right side of the vehicle.
3. Loosen the alternator belt idler pulley.
4. Slip the drive belt off the alternator pulley.
5. Remove the four air conditioning compressor mounting bolts.
6. Remove the radiator fan and fan shroud.
7. Move the air conditioning compressor forward.
8. Disconnect the alternator harness connector.
9. Remove the alternator mounting bolts, and lower the alternator from the vehicle.

To install:

1. Hold the alternator in place and install the mounting bolts.
2. Plug in the alternator harness connector.
3. Move the air conditioning compressor back into location.
4. Install the radiator cooling fan and shroud.
5. Install the air conditioning compressor mounting bolts.
6. Place the drive belt on the alternator pulley.
7. Tighten the drive belt to the proper tension with the idler pulley.
8. Install the splash guard.

TESTING

The easiest way to test the performance of the alternator is to perform a regulated voltage test.

1. Start the engine and allow it to reach operating temperature.
2. Connect a voltmeter between the positive and negative terminals of the battery.
3. Voltage should be 14.1-14.7 volts.
4. If voltage is higher or lower than specification, connect a voltmeter between the battery positive (B+) voltage output terminal of the alternator and a good engine ground.
5. Voltage should be 14.1-14.7 volts.
6. If voltage is still out of specification, a problem exists in the alternator or voltage regulator.
7. If voltage is now within specification, a problem exists in the wiring to the battery or in the battery itself.

Many automotive parts stores have alternator bench testers available for use by customers. An alternator bench test is the most definite way to determine the condition of your alternator.

Hi, it appears there are other belts in front of the alternator belt. In this case, the other belts have to come off first. There are adjusting mechanisms on each the air pump, compressor, and alternator to loosen and tighten the belts. The power steering belt is adjusted by sliding the idler pulley. Please follow the instructions below and let me know if you have any questions.

Alternator
To adjust the tension of the alternator drive belt on all models, loosen the pivot and mounting bolts on the alternator. Using a wooden hammer handle, a broomstick or your hand, move the alternator one way or the other until the proper tension is achieved.

WARNING Do not use a screwdriver or any other metal device (such as a prybar) as a lever.
Tighten the mounting bolts securely. If a new belt has been installed, recheck the tension after about 200 miles (480 km) of driving.

Air Conditioning Compressor
A/C compressor belt tension can be adjusted by turning the tension adjusting bolt which is located on the compressor tensioner bracket. Turn the bolt clockwise to tighten the belt and counterclockwise to loosen it.

Air Pump
See Figures 12
To adjust the tension of the air pump drive belt, loosen the adjusting lever bolt and the pivot bolt. Move the pump in or out until the desired tension is felt.
The tension should be checked between the air pump and the crankshaft pulley on cars without air conditioning. On cars with A/C, the tension should be checked between the A/C compressor and the crankshaft pulley.

Fig. Fig. 12: Moving the air pump to tension the drive belt

Power Steering Pump
Tension on the power steering belt is adjusted by means of an idler pulley. Turn the adjusting bolt on the idler pulley until the desired tension is felt and then retighten the lockbolt.

It appears that your car is equipped with multiple v-belts, rather than a serpentine belt so there most likely aren't tensioner pullies. Here is some general info that may help.

Alternator To adjust the tension of the alternator drive belt on older models, loosen the pivot and mounting bolts on the alternator. Using a wooden hammer handle, or a broomstick as a prying device, move the alternator one way or the other until the proper tension is achieved. Do not use a screwdriver or any other metal device such as a pry bar, as a lever. Newer models use a tension adjusting bolt. Loosen the pivot bolt and the locking bolt, then turn the tension adjusting bolt until proper tension is achieved. Tighten the bolts securely, run the engine about minute, stop the engine then recheck the belt tension. Air Conditioning Compressor A/C compressor (always use caution when working near the A/C compressor to avoid damaging the refrigerant lines) belt tension can be adjusted by turning the tension adjusting bolt which is located on the compressor tensioner bracket. Turn the bolt clockwise to tighten the belt and counterclockwise to loosen it. Air Pump To adjust the tension of the air pump drive belt, loosen the adjusting lever bolt and the pivot bolt. Move the pump in or out until the desired tension is reached. NOTE: The tension should be checked between the air pump and the crankshaft pulley on cars without air conditioning. On cars with A/C the tension should be checked between the compressor and the crankshaft pulley. Power Steering Pump Tension on the power steering belt is adjusted by means of an idler pulley (some models may use just a lower adjusting bracket setup, similar to the alternator adjustment service procedure). Loosen the lock bolt and turn the adjusting bolt on the idler pulley until the desired tension is felt, then tighten the lock bolt.

it sounds like a loose compression compressor.

if the compressor is loose compression, normally it sounds noisy. then suction pressure is above normal and if you accelerate and maintains that high speed, let say 2000 rpm, the suction pressure goes down to the normal level and cools your air conditioning .
