    The plate is off but the hole is still not big enough to get it out. We are taking the radiator out right now. Thanks

There is a plate under the car on passenger side. Remove this plate and you will be able to see the alternator. I think it has three bolts

    Why the thanks for trying? I never said you could remove it through the hole, I do this for free that rating is not very nice.

REPLACING ALTERNATOR IN 2007 lUCERNE


If you are on the fence about changing your alternator yourself, let me say: Don't do it!!! This is not a novice job. I spent about 4 hours getting it out and about 3 putting it back together, including about a 1 hr trip to the parts store. I'd say I lost 1-2 hours for having no manual or guide on how to do this work. If you are intent on doing this yourself, the next paragraph will describe the steps necessary. You'll have to fill in your own curse words during the exercise! LOL
  1. Remove the lower plastic cowling to allow undercarriage access
  2. Remove the upper plastic cowling to see the radiator
  3. Loosen the radiator overflow tank
  4. Remove the stabilizer bar that runs front to rear over the serpentine belt
  5. Remove the stabilizer bar mounting bracket that is attached to the engine just above the alternator
  6. Remove the steel body bar that runs left-to-right in front of the engine (I didn't find this until late, costing me extra time) You will need to remove the cover to the fuses to get at one of the bolts. 4 18mm bolts.
  7. Remove the bolts and body nuts that attach the front grill and upper bumper to the chassis
  8. Optional - Remove the air breather assembly if you need more room on the right side of the car - it's an easy pull
  9. Remove the upper radiator hose
  10. Remove the upper radiator clamps
  11. Remove the engine fan tray
  12. Optional - remove the radiator Or
  13. Tilt the radiator back with not enough room to properly work
  14. Remove the alternator
  15. That's it. Now Reverse the steps.
Here are a few notes:

Fan tray - held to radiator by an upper and lower clip. Also, there are two hoses bolted to it on the right side along with the power cables..

Radiator - if you are going to leave it in and work around it, you need to lift it from it's center supports so that it can be tilted towards the front of the car. You run the risk of damaging the radiator as is not enough room to maneuver the alternator out without striking it.

You will need a second person to pull back on the radiator during the alternator removal. I used a bottle jack and a piece of lumber to push it forward as I had no helper. The only way to get the radiator leaning far enough to work was to also have the front grill pivoting forward as well. In reality, you need the bottom section as far forward as possible and less so the upper.

Air Conditioner - In every step of removing anything, the AC hoses were in the way. Sure would have been much easier if I could have pulled those hoses off.

Alternator - Has 3 bolts. Reach one from under the car. It is the pivot bolt. It is a 15mm bolt and nut. Best with a helper as the nut is best held from above and the bolt from under. Next bolt was removed from above. It is located on the alternator face. It took me a while to realize that there was a third bolt that is at a 45 degree angle upwards on the front side of the unit. It's also the battery ground wire location. Also remove the hot wire and the 2 wire connector.

How do u change the alternator


this is not an easy job-you need to remove lower splash shield, air dam, passenger tire and inner fender on the passenger side, the surge tank, drain the radiator,, remove the air box and intake tube, move the engine computer and position it out of the way-remove the headlights, remove the bolts that hold the radiator to the radiator support and frame, remove hoses, remove the bolts that hold the radiator fan to the radiator core, remove the top support, remove the fan harness...then, remove loosen the compressor, move it out of the way then unbolt the alternator and the alternator harness. It will take 2 to 3 hours to do all of this, these were not designed to take apart easily.

Can't remove the alternator! How do you remove the alternator on a Ford Focus 2001 without unbolt the engine mount?


The other option, but be warned could cause damage to the motor mounts, is to use a cherry picker to lift the engine up enough to clear the alternator from the engine bay.

Best way to replace an alternator on a 1988 honda accord


Disconnect battery.
Remove under engine shroud if it's still there.
The alternator is at the front of the engine down low on the radiator side.
Loosen drive belt, the alternator can be removed by patient use of a 14mm wrench, the wires should be removed before dropping the alternator out. Frankly I forget whether they are in a jack or screwed on.
It is necessary to turn the alternator sideways to get it out.
Have fun!

How to replace a thermostat on a 2003 chevy trailblazer with a 4.2 engine. One source says it is off the top radiator hose, and another says it comes from the bottom hose right behind the alternator. If it...


The thermostat is under the alternator.

If you have a memory saver to keep radio & PCM settings, install it now.

Remove negative battery cable from battery. Remove positive cable from alternator and disconnect harness plug from alternator.

Remove accessory belt noting how it is installed for later reinstallation.

Remove engine lifting hook in front of alternator.

Remove (3) bolts holding alternator on.

Drain coolant from radiator (may want to start this as first step as it takes a while). Loosen pressure cap to aid in system draindown.

Remove radiator hose from thermostat housing.

Remove two bolts from housing and remove from engine.

Reinstall is reverse keeping in mind the following:

Cleanliness counts where thermostat housing seals to engine.
Thermostat spring should point into engine.
If the thermostat has a bleed port, it should go to the 12 o'clock position (up).
