Battery removal i need to replace the battery and dont know the proper way to take it out

Disconnect the battery: Before beginning any work on the electrical system of your vehicle, disconnect the battery to prevent accidental shocks or short circuits.
Remove the steering column cover: The ignition switch is located on the steering column, so you'll need to remove the cover to access it. Depending on the exact model and trim level of your Montero Sport, the cover may be held in place with screws or clips.
Remove the ignition switch: Once you have access to the ignition switch, you'll need to remove it from the steering column. This may involve removing any retaining screws or clips that are holding it in place, as well as disconnecting any electrical connectors.
Install the new ignition switch: Install the new ignition switch in the reverse order of the previous steps, making sure that it is securely fastened to the steering column and that all electrical connections are properly connected.
Test the new ignition switch: Once the new ignition switch is installed, reconnect the battery and test the switch to make sure that it is working properly. Insert the new key and try to start the engine. If the engine starts and the key can be turned smoothly, you've successfully replaced the ignition switch.
It's worth noting that depending on the specific make and model of your Montero Sport, the exact steps for replacing the ignition switch may vary slightly

Look on youtube if there are any videos for that. I dont know your car but on same autos even qualified mechanics with proper tools need 8-10 hours to replace mounts because many things need to be removed to gain acces

If it will start by jump starting, then the problem is either the battery or the alternator, or both. If the car has proper voltage (or the battery light is not lit) while the engine is running, and if the battery is more than three years old, I'd suspect the battery is the problem. If the voltage reads less than 12 volts or the battery light is lit while running, the alternator is not producing enough power to keep the battery charged. This may mean that the alternator only needs replaced or the alternator and battery may need replaced.

i believe the battery replacement is coincidental.the rear spindles of these vehicles dont drain water properly and as a result corrosion build up forces a white plastic cover on rear of knuckle against the wheel speed sensor which in turn rubs against huib assy.causing false wheel speed signals which engage the abs.simple to check.remove both rear sensors from spindle and look for evidence of rubbing.look CLOSELY its not always obvious at first glance.nissan has a service bulletin for this incident.contact local dealer parts dept. they'll know what you need.

Take it to a garage and pay the $24 to have them install it, they are responsible for the radio codes and any other problem that can occure when changing a battery in the newer cars.

No, it should immediately start if you have the battery connected properly. Are you sure this new battery is fully charged? It may just need charging. If the battery is fully charged and connected tightly then you have another problem.

First unhook battery. Then unplug connectors and wire. Loosen bolts to take tension off of belt. Remove belt remove bolts holding alt. Place new alt in spot remember wich holes go where so not upside down replace bolts dont tighten yet. Install belt on all pulleys tighten tensioner bolt on alt bracket to snug tension after proper tension is achieved tighten all bolts and nuts. replace all plugs and wires reconnect battery pay attention to pos and neg dont hook up battery backwards. Congrats your done.

first unhook the battery, remove the air cleaner box and ducting to the throttle body, you will see the 2 bolts for the top. you will then need to go under the vehicle(make sure the vehicle is properly supported), and you will see the bracket between the engine block and the intake manifold, remove it.the starter wire does not get removed from the starter, it has a connector about 4-5 inches away. disconnect it there. disconnect the battery cable from the starter, remove the last bolt and it will come right out. all in all it takes about 30 minutes. most places will charge a "core charge" on a product like this. dont be suprised, however when you return the old starter you will get your money back. let me know if you need further assistance.

Very possible that selenoid is bad-did you have starter tested?(auto parts stores do this)Check all cables going to starter for corrosion and loose connection at starter. Corrosion gets inside of cables over time, so replace when in doubt. INSTRUCTIONS-remove negative cable from battery and move away from battery(tie off), on selenoid if fender mounted, remove cables from both sides of selenoid(is stamped with letters B and I)-when you remove, mark with tape which is I and which is B, in case replacement is different from old unit. then remove from fender(save bolts)-install new part on fender, and replace cables on proper sides(B or I). install neg. cable on battery-try to start....good luck!!!

Check under your rear seat. If you dont find it there it is Mounted in the the gastank. I would suggest you dont drop the tank and take it to a shop for them to do it. THere are special tools used to remove the gasoline in the tank and also remove the pup itself. If it is in the seat then disconnect the battery and its just a fuel bolts that you can remove. If you remove it make sure to cover the hole where your pump was . You dont want to ignite those Fumes in the sun.
