In this clip we are going to talk about some of the things that may need disassembled in order to gain access to your alternator The components that require disassembly are going to vary from vehicle to vehicle. It may or may not be required for the vehicle that you are working on and some other components may need disassembled for the particular vehicle. This happens to be a 97 Ford F 150. In order to gain access to our alternator, we are going to have to remove this upper radiator hose and get it out of the way. We are also going to have to remove this bracket back here which is holding our ignition cables in place. The radiator hose is pretty cut and dry. It's got your typical style hose clamp up the radiator. Take the flat head screwdriver or a 5/16's socket. Get it good and loose. What I like to do is slide it down a little bit on the hose and snug it back up just a fuzz that way it doesn't fall off when you flip it out of your way. Depending on the coolant level, you may or may not have to drain some coolant out of the bottom of the radiator. This one we've already drained and there's a small valve that looks like a household spicket on the bottom either the right or left hand corner. You are going to want to drain out approximately half a gallon and save that coolant so you can add it back to the vehicle when you are finished with the repair. Once the hose clamp is off, we will just take the hose and flip it out of our way and tuck it back over here. Make sure it is tucked and secure because there is a little bit of tension on this hose that may want to flip up and smack you in the head as you are performing the rest of the disassembly. There are some 10 millimeter bolts that happen to hold the ignition bracket on. Just take and break them loose. It depends on the particular vehicle you are working on; this is a Ford. You can see the way I am working this ratchet. As I am ratcheting it, I am actually holding on to the extension and when I loosen the bolt, I let go of the extension. That makes sure you get a 100 percent effective stroke as you are ratcheting. Otherwise when the bolt begins to get loose, your ratchet may want to free wheel on you some costing you a little bit of your time. Here's our first one, put that in my pocket. As these bolts get loose, you may find that it is easier to actually just take the extension in your hand, slide it on there and use it kind of like a screwdriver. I'm going to put that one in my pocket and we have one more here to contend with and that's in my pocket. Once we've got this bracket loose, it is going to allow us to manipulate these cables so we can gain access to the clips on the back of the alternator.
