Question about 2007 Nissan Sentra 2.0 SL Sedan
Hi, the spark plugs are located inside spark plug tunnels which are through the valve cover. 2007 nissan Sentras are equipped with individual coils for each plug. So to get to them, first remove all the plastic coverings over the valve cover. 10mm socket and 1/4 inch rachet with a 6 inch extension should do the trick. Before disconnecting electrical parts please disconnect the battery. Remove wiring looms for coils. Remove bolts for coil packs, lift coils out of tunnels. Spark plugs are down inside the tunnels. Use the proper sizing for plug removal. A 3/4 inch rachet with deep spark plug socket and 6 inch extension should get them out. When replacing spark plugs, thread them by hand first, usually a good 2 or 3 full turns and be careful not to over tighten. The plugs screw into the alluminum cylider head. Alluminum is soft and you can quickly ruin the threads. Installation is the reverse of removal.
