  1. Use a 1/2 inch breaker bar with a socket placed on the tensioner pulley axis bolt and rotate the tensioner to the left (counterclockwise). CAUTION: Do NOT allow the drive belt tensioner to snap into the "free" position as this may damage the tensioner.
  2. Remove belt.
  1. Route belt over pulleys except the belt tensioner.

How to replace a 1998 Ford contour alternater

The Contour alternator is somewhat harder to remove and replace than many cars. The 2.5-liter V6 engine is especially difficult, requiring removal of the right half-shaft to gain access.


2.0 Liter engine (4-cylinder)

1. Disconnect the negative battery cable.
2. Remove air intake resonators.
3. Remove the air cleaner-to-throttle body tube and the mass airflow sensor.
4. Unplug the connectors and remove the cables from the alternator.
5. Raise and support the vehicle.
6. Release the drive belt tensioner and remove the drive belt from around the alternator. (It is not necessary to remove the drive belt from the engine.)
. Remove the alternator mounting bracket bolts and remove the mounting bracket.
8. Lower the vehicle.
9. Remove the power steering pressure hose bracket retaining nut and bolt and remove the bracket with the hose from the engine lifting eye.
10. Remove the alternator mounting bolts and remove the alternator from the vehicle.
11. To install, reverse the procedure.
2.5 Liter engine (V6 engine)

1. Disconnect the negative battery terminal.
2. use a box-end wrench to turn the tensioner pulley clockwise to release tension on the belt. Remove the drive belt from around the alternator. (It is not necessary to remove the drive belt from the engine.)
3. Raise and support the vehicle.
4. Remove the wheel.
5. Remove the wheel well splash shield assembly.
6. Disconnect the outer tie rod from the knuckle assembly, then remove the hub nut from the hub.Tap on the outer spline of the half shaft to make sure it is separated from the hub. Use a hammer and a block of wood to avoid damaging the spline by directly hammering it.
7. Remove the front exhaust Y-pipe from the exhaust system.
8. Unplug all the wires and connectors attached to the alternator.
9. Remove the retaining bolts from the alternator brace and then remove the brace.
10. Remove the halfshaft by pushing out on the knuckle to separate it from the hub and then prying it out of the transaxle with a large pry bar. (Be sure to set a pan beneath the transaxle to catch the fluid that will drain out.)
11. Remove the alternator mounting bolts and remove the alternator from the vehicle.
12. To install, reverse the procedure.

Good luck!

Replace alternater belts

The 3.5 engine uses a serpentine belt which runs everything.
You would release the tension on the tensioner pulley and remove the belt. There should be a diagram on the hood or radiator support showing the belt routing. If not, be sure and draw a diagram before you remove the old belt.

Where is alternator located on 1996 cadillac deville? how do you replace alternator on 1996 cadillac deville?

The alternator will be located in the front of the engine on the drivers side. To replace it you must loosen the idler pulley and remove the serpintine belt, once the belt is off you must unhook any wires goin to the alternater and then there are two bolts at the bottom of the alternater holding it in place. Remove those and the alternater is loose then it may take some jockying back and forth to get it out. Obviously at this point the new one can go in the same way the old one came out.

Change alternater. how do I lossen serpen tine belt to get to alternater

There is a spring loaded tensioner on the belt line. You can put a wrrench or socket, usually 15mm, on the bolt and put pressure to turn the tensioner. Then carefully remove the belt from the pulley and gently allow the tensioner to release. When re-installing it. be very careful not to have your fingers under the belt, there is a large amount of pressure on the pulley.

How do you take out an old alternator and install a new alternator in a 97 honda civic

From the top of the car remove the slide and anchor bolt from the alternater bracket. remove your 3 or 4 pin plug and diconnect the pos power line beside the 3 or 4 pin plug ( on the back of the alternater). now raise the car and from below remove the lower bolt that allows the alternater to swing back and forth. the bolt fits through the housing of the alternater. remove the belt. now the alternater is free. this lower bolt that was just removed attaches to a bracket bolted to the block. remove this bracket and the alternater will slide out of the bottom of the car. complete the above steps in reverse to install new part.
