Question about 1997 Mercury Mountaineer
I need a new alternator, tensioner, and belt drive pulley- i am poor and know very little about cars- i want to do this myself- i asked 10-15 people and got many different answers- i was told if i do it myself i could screw up the timing and blow the engine- if the car is running it is charging therefore i dont need a new alternator- to replace the cheapest part first and see if it fixes it- i took it to a tires plus and they want to charge me double for the parts and $400 in labor- i really want to be able to do this myself- is it possible without screwing it up? and is any of what people told me true?
It is very important that you know exactly what you are doing when you replace a drive-belt pulley! It is possible that if you get the timing wrong that your engine will fail! The alternator can be replaced with little knowledge but if your car starts and runs then there is no problem with the alternator nor the timing. If your belt looks worn down or has fray marks on it then i would suggest to change it. Also, unless the tensioner is cracked or broken there is no need to replace that.

Excessive belt tension will cause damage to the alternator and water pump pulley bearings, while, on the other hand, loose belt tension will produce slip and premature wear on the belt. Therefore, be sure to adjust the belt tension to the proper level.
To adjust the tension on a drive belt, loosen the adjusting bolt or fixing bolt locknut on the alternator, alternator bracket or tension pulley. Then move the alternator or turn the adjusting bolt to adjust belt tension. Once the desired value is reached, secure the bolt or locknut and recheck tension.

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.
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.

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.
