I assume you are referring to the side mounted terminals on a battery. They are very easily stripped if the wrong wrench is used or more commonly when pliers are used to tighten or remove. I have found that the best tool to use in this and similar situations is a 6" pipe wrench. It will damage the bolt but that's already the problem. It will remove a bolt that is completely rounded off. Just put it on the stripped bolt and apply a little counter-clockwise pressure and the bolt will loosen. Be careful as it is possible to actually loosen the entire terminal block requiring a new battery. It is probably stuck because it was overtightened in the first place.
Every situation is different but for the most part the wrench holds while the socket turns.
If the nut or bolt is really stuck, the impact will crack a conventional socket.
1/2 socket and wrench and rubber mallet
if u know were the spark plugs are located use a socket wrench with long socket so you could fit the socket into the hole and do the exact same things as you would do trying to get a bolt free
Ur gonna need a socket extender and a socket wrench boi
because the bolt is tight with an adjustable wrench and usually an adjustable wrench isn't strong enough so I would use a socket wrench but if the socket wrench doesn't get the nut loose for you then try a skateboard key (skate tool) to loosen the nut but if that doesn't work I don't know what to tell you other then to visit a skatepark because they will explain why the nut wont come off
Dead short to ground in either: Parking light socket or wire to Tail light socket or wire to Dash panel lights Remove 1 bulb and/or socket at a time to try to determine which is bad
Specialized tools are tools that are meant for one job only. Let's take something like a pipe wrench for instance - it can be used to hold or turn pretty much anything within a certain size range. Now if you'd compare that to a socket wrench, the socket wrench would only to be able to turn hexagonal nuts/bolts of one size, so it'd be a fairly specialized tool.
First you need to remove that support bar that's blocking access, 13mm bolt is accessible just behind the fuse box, if you have an extended socket. If you do not have an extended socket, you will need to loosen the fuse box screw with an 8mm wrench. The support bar will slide out after it is unbolted. Disconnect the battery terminals with an 8mm or 5/16 wrench. Then remove the battery hold down bolt, 13mm socket. Now, take the battery out-be patient, it's a tight fit but it will come out. I just changed the battery on our 2006 Rendezvous 3500 V6. I found the above answer to be helpful, however I would like to add the following: To obtain sufficient clearance to remove the battery, the radiator cap must be loosened 1/4 turn so that the cap tabs are out of the way. DO NOT LOOSEN cap while coolant is hot. Also, remove overflow hose at cap location for extra clearance using pliers to open the clamp and slide the hose off. Next, notice the small guard by the the serpentine belt and pulley system that a wire harness is attached to. A 10mm bolt can be felt underneath the metal plate; remove using a 1/4" socket and ratchet. Hand spin it off carefully and don't drop it! The battery may have a foam wrap which must be removed. Lift the battery out by tilting and bringing it upward. Set the new battery in, install battery hold down bolt with a 13mm socket. Re-install the harness plate (start bolt by hand) and secure it with a 10mm socket. Turn the radiator cap back to the original position and re-attach the overflow hose. Connect the battery posts - positive first and negative second. Tighten with an 8mm socket. Re-install the support brace (hint: put some gum or a piece of kleenex into the socket and press fit the bolt into the socket). Re-install the front two bolts of the support brace. Start the car!!
Your lamp could be blinking because the battery might be low so you need to replace the bulb. Or the socket its plugged into might be faulty so you would have to change the socket.
Take off the gas cap. Take off the big plastic cover with a socket and wrench.Then put the gas cap back on. Then pull of the spark plug boot. Then take off the spark plug with a spark plug socket and wrench. It should be 13/16" socket with 3/8" drive wrench. I Think the spark plug gap is 0.025 but you would have to look at a manual.
If you are 100% sure the alternator is good, then either the wiring or the battery are bad. If the battery has a dead cell it will not hold a charge. Disconnect the battery cables and clean the connections. Charge the battery with a battery charger, and then connect the cables. If the battery is over 3 years old, it is more than likely bad.
