The correct size socket and ratchet to remove the hold down. And the correct size socket to remove the battery cable clamp.
Take a socket set and test each socket until you find the correct size that fits snugly.
Take your socket set and try various sockets until you find one that fits...then look at the size on the side of socket...BINGO!!! now you know the size.
The heads take a 19mm socket
14mm or 9/16
You need an 18 mm spark plug socket.
22mm

You need a fitting socket, a socket wrench and an extender. Anyone who works on his own car will have a set.
It will take a 15mm socket to r&r them.
