How To Replace your Mustang's Battery


No matter how impressive your Ford Mustang may be in outward appearance, if it doesn't have a good and reliable Mustang battery then it will not be able to function as you'd like it to. In most cases, you'll have a clear indication from the vehicle if you need to change out the battery; the car will simply have problems starting or may stall out and stop at various points as you're driving. When this happens, it's a good idea to check the cable and the attachments of the positive and negative terminals to be sure that there's a steady and healthy connection. If that doesn't seem to be the problem, take your car to a service station where you can test the charge on the battery. You may even need to get a jump from another car with a battery that works properly.

If none of these things seem to help your situation, it may be time to replace the battery in your Mustang. Fortunately, this process is easy. Always use caution when replacing a battery to be sure that you don't put yourself in danger.

Step 1 -- Gather Your Materials

You'll need the following materials in order to replace the battery on your Mustang:

  • Replacement battery
  • Socket wrench
  • Terminal puller device
  • Wire brushes
  • Gloves
  • Goggles or other protective eyewear
  • Screwdriver

Step 2 -- Locate and Prep the Battery

When the car has been off and the engine has not been running for several hours, open up the hood of your Mustang and locate the battery on the driver's side. Begin by removing the large black bar that stands in between you and the battery. This should come out by hand, although you may need the screwdriver to help pry it out carefully.

Step 3 -- Disconnect the Existing Battery

Begin by removing the ground wire by hand. Be sure that the wire itself doesn't touch any other part of the car as you remove it, and then set it aside carefully in a place where it will not contact any other metal. If you do happen to touch it against something else that's metal, you may need to replace it entirely, so it pays to be careful with this part of the process. Next, disconnect the terminal ends of the battery as well, using the battery terminal puller device. Begin by disconnecting the negative terminal, then disconnect the positive after that.

Step 4 -- Remove the Battery and Clean the Holder

Carefully lift the battery out of the compartment. use a wire brush to then clean off the surface of the battery compartment to be sure that there is no debris or any other buildup inside of it when you install the new battery. You may even wish to use a damp cloth to clean off the area as well.

Step 5 -- Install the New Battery

Finally, place the replacement battery inside of the now clean battery compartment. Attach the cable ends to the positive and negative terminals on the battery, then use the socket wrench to help tighten them in place so that the connection is secure. Reattach the ground wire as well, and be sure that everything is properly connected before you continue. Finally, reattach the black bar that you had to remove initially which stood in the way of you and the battery. Close the hood and check on the car to be sure that the battery works.
