You can move these heater hoses out of the way. Just pull them out of the bracket and slide them to the side. Then you can access the coils.

You can take this wire off right here. Just twist it back and forth. You should be able to do it with your hand, and just slide it off like that. Disconnect the connector. There's a little tab. Just pull up on the tab, slide it out. Now just take a ten millimeter socket, take this bolt out here and the one right there. Get those bolts out. Grab the coil, just slide it up.

Take the new coil. Set it in position. Put the bolts in. Get those started. Right there and right there. Then I can torque these bolts to 71 inch-pounds. Plug in the coil. Lock it in place. Take the coil wire and slide it on. Then we're gonna do the same procedure for the rest of them.

And move these heater hoses, put them back in the bracket.
