2006 Murano spark plug change

[Carguy75]

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.

Can't wait to see your next step because I need to replace my spark plugs soon too

This is Section 2 of how to do a Nissan Murano spark plug change. First remove to engine cover, you will need a square bit to remove bolts. Next, you will be removing the center air duct assembly. Do not forget to remove the PVC hose from duct assembly. Next you will unbolt the round vacuum in the center and the VIAS control solenoid valve also in the center. You do not have to unplug them,I move them off to the side while I worked. Next remove the wiring harnesses from it posts by using a set of pliers to squeeze the clips ends together and remove the clips from their posts.Freeing the wiring harness will help give you room to work on the first set of sparks plugs closest to the front. Next unbolt the EVAP control solenoid in front of the throttle body. You do not have to unplug the rubber hoses, just move them to the side. Next unplug the rear PCV hose connected to the PCV valve in the rear of the engine on the passenger side. Also remove the power steering hose bracket in the rear of the engine to the right of the PCV valve using a 10mm socket. Do not forget to remove the harness bracket in the rear of the intake manifold collector as well.It has one 10mm bolt holding it in place. Look around the engine and unplug any harnesses or rubber hoses that is connected to the intake manifold collector and engine. Next remove the five 10mm bolts that holds down the intake manifold collector in the center. Then remove the two 10mm bolts in the rear support bracket behind the throttle body. It is a very tight fit between the support bracket and the fire wall. Now you should easily be able to lift the intake manifold collector of the engine, if not check for any harnesses or hoses still connected. I just gently moved the intake collector off to the side as I worked. Next cover the intake ports with some paper towels prevent anything falling inside them as you work. Now, change spark plugs as normal. First unplug coil pack, then remove coil packs, and next remove spark plugs. Section 3 coming soon.

This thread was also very detailed. Warhammer did I great job.
I actually printed some of those pictures and used them as a reference when I changed mine.

You are right. I wished I would have found this walk-through before I did my spark plugs. I hope my pics and his pics combined will help someone do the job themselves. I did not get too technical with the line pointing because I decided to make a how-to for people who already know how to change spark plugs, but only need to know how to remove the cowl and intake collector only.

Holy crap! How long does a spark plug change take?

Man, I was thinking the same thing when I first asked Nissan's service department how much to do it. I was feeling lazy. When Nissan's service told me 500+ dollars because of the labor involved, I asked why and was told that I had to remove the entire wiper assembly, cowl section, and intake collector. I was amazed that Nissan did not think ahead about making the Murano easier to maintain. I have removed intake manifolds on other car brands before to remove spark plugs-2005 Mercury Montego and 2005 Volvo S40, but never to this extreme as with the Murano. All and all it took me five hours to complete the job, I could have done it quicker if I did not stop to take pictures and charge my power tool. So maybe a three hour job.

Ya thats still a bit of time consuming. Would this also be a quick way to access the incabin filter? Just wondering if this would be a good time to change it since the wiper cowl is off... Unless thats a different process on this car.

The incabin air filter is behind and above the glove compartment and can be easily changed from inside the vehicle, you can see it when you open the glove box.

Search for the threads on this. It's in the cabin behind the glove box and takes all of five minutes to change.

That is actually really scary! It boggles my mind what has to be done to change apsrk plugs. I could never attempt to do that, I'd end up with a car that wouldn't be drivable. If I have my car long enough to need plugs, I'll either sell it, or pay the money to have the plugs changed!

[Carguy75]

Nissan is odd. The cabin air filter is the easiest cabin filter to change in any car I owned before,just open the glove box and reach in and swap filter out, done, but it requires a complete engine bay disassembly to change only three spark plugs in the rear of the engine. Oh well, I still love the Murano. But, I would began to hate it if I had to pay someone else to fix all the little problems that have creeped up lately. Wheel bearings, gas door, sparkplugs, power steering hose, and broken driver's seat frame. I would be in the poor house if I had to pay a mechanic everytime it needed something repaired. DIY is a must for a Murano owner without a factory warranty.

Carguy75, I was fascinated by the great pictures and story on how to change out the plugs. I'm doing this job tomorrow. I've read your post several times and it says that part III will come shortly, but I can find it? Thanks again......wish me luck.

Sorry, i never made a part three because someone else already posted a how-to in the engine maintance section of this forum. I posted part one and two before someone mentioned that fact to me. The one listed in the maintance section is just as detailed or more than the one one I was doing. P.S. part three was just the reversal of the part one and two, reassembly.
