Replacing the battery then requires that you unfasten the cable attaching it to the negative terminal then the positive terminal. Next, take out the battery hold-down clamp and then extra carefully lift out the rather heavy battery ahead of them. Battery strapping and handling straps can be obtained at auto parts store near you in order to ease on this process. When putting a new battery make sure it is of a different capacity size, and an amperage and cold cranking rating as the old one, and take the heat shield of the battery and place it on the new one. For the battery tray, you just have to un-bolt the battery and depending on your own preference; you can unbolt the air filter assembly for more easy access. Next, you must unscrew the bolts and the tray of the battery compartment. The reinstallation is done in the reverse sequence, that is the positive cable is connected first while the other end is connected the last.
