This applies to 3.6L V6 engines and the interval is different for 2.4L 4 cylinder engines. In some cases, the spark plugs may fail as early as 60,000 miles. In such situations, the check engine light may turn on. Diagnostic trouble codes will be stored in the ECU and can easily be retrieved using a diagnostic scanner.

Tools you will need

This is a list of tools that you will need to change the spark plugs and ignition coils on a 3.6L Pentastar engine. We hope you already have most of these tools. If you don't, we recommend that you invest in a mechanic tool set that has all these tools. 

  1. Allow the engine to cool down. Open the hood. 
  2. Disconnect the negative battery terminal. 
  3. Remove engine cover by pulling it up. You don't need to remove any screws to remove the engine cover. 
  4. Disconnect the vacuum lines. 
  5. Disconnect the air intake from the throttle body. Disconnect any vacuum tubes connected to the air intake tube. Loosen the 8 mm hose clamp screw. Unplug the air temperature sensor near the throttle body. 
  6. Remove the 8mm bolts (in some engine these may require T30 Torx bit) that secure the intake plenum (manifold) to the top of the engine. There are seven bolts that need to be removed.  These are long bolts and don't need to come all the way out. Remove the two 10 mm bolts on the front. Remove the two 10 mm bolts on the back of the intake to replace spark plugs chrysler penta star Remove one 13 mm bolt on the metal bracket and push the bracket back. Next, lift up the intake manifold and move it aside. Cover the intake with a clean newspaper so that no foreign object or dirt falls inside the engine. 2012–2015 Lancia Voyager (Models: Limited)
  7. Rubber Gaskets between the plenum and intake manifold. 
    When you remove the intake plenum you will notice that there are three rubber gaskets between the plenum and intake manifold. These gaskets are typically integrated into the intake manifold part and don't necessarily need to be removed. Do not add any silicone or gasket sealant here as it is not necessary. The most important thing to do is tighten the intake plenum bolts to spec as described in the following steps.  2012–2014 Lancia Thema
  8. Remove the 10 mm bolts that hold the ignition coils in place. 2012–present Jeep Wrangler (Models: Sport, Unlimited Sport, Sport Unplug the electrical connectors from the ignition coils.  2011–2014 Volkswagen Routan (Models: S, SE, SEL, SEL Premium)Ignition coil removed.  2011–present Jeep Grand Cherokee (Models: Laredo

  10. Be careful so that NO foreign materials fall into the combustion chamber via the spark plug holes.  Install the new spark plug by lowering them slowly. Note that all spark plugs that are iridium or platinum spark plug should come pre-gapped. You should always double check them and make sure they are all gaped correctly before inserting them into the cylinder head. Use the extension and your 5/8" socket to tighten the new spark plugs. Tighten the spark plugs to 10 ft-lbs. If you are not using a torque wrench you may want to get your spark plugs snug then turn an extra half a turn.  2012–present Fiat Freemont
  11. Add a coat of dielectric grease to the end of coil pack boot. 2011–present Dodge Charger (Models: SE, SXT, SXT +, SXT Rallye Edition)Insert the coil into the spark plug hole. 2011–present Dodge Journey (Models: SE American Value Package (AVP) or Canadian Value Package (CVP), Mainstreet, Crew, Crew Lux, SXT, R/T Crossroad)Tighten the 10 mm bolt until they are snug, don't over tighten these bolts.  2011–2015 Dodge Grand Caravan (Models: SE American Value Package (AVP) or Canadian Value Package (CVP), SE, Crew, Crew Lux, SXT, R/T SE Plus, SXT Plus)
  12. Install the plenum. If you have new gaskets to install between the intake manifold and plenum now is the time to replace them. Otherwise, go to next step. 
  13. Install the plenum in reverse order of removal. The 7 bolts will need to be torqued to 7-9 Nm (5-6.6 lb/ft). It is important that these bolts are torqued to spec. 
  14. Next, tighten the two 10mm bolts in front of the plenum. 
  15. Next, install the bracket on the other side of the plenum. Place the bracket in place and tighten the 10mm and 13mm bolts. 
  16. Next, reattach the air intake tube to the throttle body. 
  17. Reconnect any vacuum hose you disconnected earlier such as PCV hose and makeup line. 
  18. Reconnect wiring harness that you may have removed.
  19. Reinstall the engine cover by placing it on top of the engine and pressing it down until you hear it lock. 
  20. Reconnect the negative engine terminal. 
  21. Start up the engine and make sure the engine is running smooth.
