Today I changed the spark plugs in my wife's 2006 Murano. It was time consuming,but worth doing myself instead of paying the Nissan service department 500+ dollars to do it. Here are the pics and some directions on how to do it yourself. I looked but not could not find one person who have done it themselves with pics. So here goes Section 1 on how to do it. Tools needed - Socket Wench, Torque Wench, 10mm socket, 14 mm socket, low profile bit socket for tight areas with 10mm bit socket, painters tape to mark wiper arm position, paper towels, power screw driver or driver"helpful, but not necessary", Slim spark plug socket with long extension or two regular extensions, and patience. First mark the wiper arm position using painters tape, next remove round plastic dust cap on wiper arms to access the nuts to be removed. The nuts are 10mm or 14mm, I had to change sizes a few times during the process. Must nuts on the Murano are 10mm, but a couple nuts are 14mm. Then remove the rubber weatherstripping off the plastic cowl by removing clips with a clip removal tool. Next, unclip the plastic cowl from the metal cowl, but be careful with the washer nozzle tubes underneath, because they have to be removed before the plastic cowl can be removed. Next remove the wiper motor assembly by removing three 10mm bolts. Next, remove a number of 10mm bolts that secures the metal cowl to the body. I used a power impact wrench to do it quickly, but can be done by hand. Next remove washer tube from metal cowl and remove cowl. Next is Section 2.
