Isuzu alternator How do i replace the alternator do i have to remove the whole engine from the top or can i work from the bottom?

the sensor is under the timing belt cover at the top of the engine. If you are looking at the engine you'll see a black strip covering your spark plugs, your electrical connection on the camshaft position sensor is under there go ahead and disconnect the sensor. Next is the removal of the timing belt cover. You will need to take the bolts holding the cover in place they will hold it all the way down to the bottom of the engine. The bolt in the center top section is actually the bolt holding the sensor in place inside the engine so you will need to look and see how to maneuver the sensor out after the bolt is removed. Replace with new sensor and replace bolts. Plug electrical connector into the top of the sensor and replace spark plug cover. You are now done. have a good day !! 2.2 engine,

If you are hearing a loud "knock" and it is coming from the bottom of the engine you probably have a bad crankshaft bearing(s) which means engine rebuild or replacement.

Slacken injector pipes and check your getting fuel.The fuel tank is a fault with the trooper, The feed pipes are at the top of the fuel tank, and corrode causing the main feed pipe to draw in air.You have to remove bottom pan under tank and then the three bolts each side of the tank to drop down,taking care not to pull on the outher pipes.im quite sure that's your problem.Any ait that can get sucked into the fuel line.That engine will not start.

On the drivers side on the bottom front of the engine.

look at your belts the alternator will be eather on top or bottom of your engin.

You need to loosen the alternator so the belts become slack. Look for bolts on top and bottom that attach the alternator to a bracket or the engine block. Loosen them and the alternator will move. Since the belts hook to other accessories, you may need to loosen them too. To get them back and the proper tension, you'll need a large screwdriver or pry bar to put tension on them as you tighten the bolts. I suggest you get a Haynes guide for this model that will have photos showing how this is done.

I have a 1998 Rodeo and just replaced the alternator. If I may make a suggestion, pay someone to do this. It took two of us 4 hours to replace. I am not a certified mechanic, but I know a few things about cars. I thought that I would replace it myself and save a little money! Big mistake. It is EXTREMELY hard to get too and there is NO room to work. Once you get it out, you would think that the new one would just slip back in place, not the case. I will take the car in and have it done next time. To answer your question though, yes you need to go at it from under the right side of the engine. you will need to go from the top to loosen some of the bolts. Hope this helped! Good luck!

My son just got the alternator off of my Trooper (1997) and he said removing the wheel is not necessary. He took off 2 bolts from the top and several from the bottom that were very difficult to remove but then the alternator came off pretty easy. He says if it loose then it should come off pretty easy, if it is not loose, you must be missing a bolt somewhere. He also says is you are in our area, call him and he will take it off for $100 =)

The alternator is located on the passenger side of the motor at the bottom. There is a bracket attached to the motor and the alternator. You need not take the bracket off to remove the alternator. Two bolts hold the alternator to the bracket. One bolt is on the front top of the alternator and one bolt is located on the bottom front of the alternator. The bottom front bolt is attached to the tension adjustment for the alternator. Loosen the tension screw then remove the bolt going through the tension adjustment. After you loosen the top, front bolt, the alternator should be loose enough to move side to side. Remove the top, front bolt. Now you must disconnect the alternator from the power supply. Behind the alternator is a screw with a wire attached via nut. Remove this wire. Nextly there is a series of wires with a plug on the end. It is plugged into the side of the alternator. Uplug this item. You can also access both of these from the passenger side front tire well. Something to consider is that remanufactured alternators in Rodeo's as well as the Honda Passport (which has the same engine as the Rodeo) do not work and the problem(s) associated with a bad alternator,ie; not charging, no fan blower, battery light and brake light on, still exsist after replacing alternator with reman. Use a factory original alternator if possible. It will cost a little more than a reman but will most likely save you a lot of time and headache!

Hope this helps you out!!
