I need to know how to change the back three spark plugs on my 2008 ford edge , do i remove the manifold.to get to them, is it safe

how to change front and rear spark plugs on ford 500

Ford Freestyle 500 Montego Duratec 3 0 Intake Manifold Removal

I 've copied info on spark plug removal. The front three are straight forward, but the back three are a job.

First off, if you're attempting this, I'm assuming you're someone mechanically inclined or at least somewhat of a grease monkey -
NO NEED for me to tell you how to change the first THREE spark plugs that stare at you when you pop-up your hood - These should be child play for you... if not, take your car to a shop and stop reading... (no offense)...

The back ones are the fun ones to get to!

Keep in mind you will need to move a lot of the wire harnesses around - you may have to cut a few tie-down clips or zip-ties to help you out.

1 - Remove the Air Box - Remove Air Filter - No need to dismantle the whole Unit into pieces... Loosen up the clip clamp at the Throttle Body and pull out the whole Unit -

** Disconnect the Sensors, Disconnect the Front Rubber Hose and the little valve underneath **

2 - Loosen and remove the screws that hold down the manifold (6 total I think in the front) - There is a super long one all by itself in the middle - the others are at the edges

** Also, take your time to detach the Wire Harness/Hoses strapped to the Manifold (in the front) you can do this by removing the black electrical tape and replacing later when you're done ...

3 - There is one screw under the Throttle Body - remove it - it's kinda' hidden but you'll see it.

4 - There is another one on top of the manifold towards the back - it's hidden under the hood cowl

** Look on top of your engine towards the back - Locate two rubber hoses attached to the manifold - FYI - You will be working in a very TIGHT spot, but be patient and make sure you don't give up! **

5 - Loosen/Detach Rubber Hose on the Left (Pass Side) attached to the Manifold (PCV Valve?) - Make sure you don't drop it - it connects the manifold to the Engine - it's a small "L-shaped" hose

** There is a tiny connector right below that valve, you cannot see it but you can feel it, it's easy to remove, just unplug it - AGAIN, it's a tight spot, but not impossible to work with. **

6 - Loosen/Detach another Rubber Hose on the Right (Driver Side) and your manifold is ready to come off - Move it around, and pull it out... careful with the wire harnesses around and the other hoses that are sitting on top of the engine.

Make sure you Disconnect the Mass Air Flow Sensor and Air Temperature Sensors!!!

Once you pull out the Manifold - it is easy as cakes to replace your three other Spark Plugs -

Follow the steps backwards and VOILA! - It is a LOT easier to do then all this jargon I've written

1. Spark plugs removal

1.1. Front cylinder bank spark plugs removal:
1.1.1. Disconnect the battery from car terminals.
1.1.2. Remove the engine plastic cover.
1.1.3. Disconnect the ignition coils electrical supply cable and all three coils connectors.
1.1.4. Remove all three ignition coils screws.
1.1.5. Remove all three ignition coils out from cylinder head.
1.1.6. Remove all three spark plugs out from cylinder head (straight forward).

1.2. Back cylinder head bank spark plugs removal:
1.2.1. Remove the inlet manifold out from cylinder head.
1.2.2. Disconnect all three ignition coils connectors.
1.2.3. Remove all three ignition coils screws.
1.2.4. Remove all three ignition coils out from cylinder head.
1.2.5. Remove all three spark plugs out from cylinder head (straight forward).

2. Spark plugs installation

2.1. Refit all in reverse order.
2.2. Spark plugs tightening torque = 2,8 +/- 0,3 daN.m
2.3. Ignition coils tightening torque = 0,8 +/- 0,2 daN.m

The plenum needs to be removed from the top of the engine to remove the rear three plugs, it can be a bunch of work if you dont know what you're doing. The front three plugs are easy, i would suggest buying some good plugs so you dont need to change them very often.

Need to remove upper intake manifold to reach valve cover close to firewall.
1) The location of spark plugs 456 are under the plastic shield in front of the engine. It takes an 8mm socket to remove the three bolts holding the shield once the shield is removed you will see a coil for each spark plug. Use the 8mm socket and remove the coil and rubber boots. You will now see the spark plug (note there are not any spark plug wires).
2) The location of spark plugs 123 are located to the rear of the eng. You have to remove the air intake manifold in order to get to the spark plus. Remove the throttle wire then remove the other items on top of the intake manifold.

Remove the EGR valve mounts so you can slide the manifold out. Disconnet all vacuum lines from manifold and the air filter inlet closet to manifold. Just take a general look and ensure you have all wiring and tubing disconnected then slide the manifold off the eng and EGR valve. NOW MAKE SURE you cover all intake holes (leading into the engine) with paper towels to prevent droping screws etc into the engine. Then follow step 1 above

Remove plastic cover over the engine ( three screws).
You then have access to the front three spark plugs (cylinders 1,3,5) remove the nut which holds down the independant coils and remove the spark plugs, fit new spark plugs and fit coils on the three front cylinders.
Now it gets a little tricky, you will only be able to access number 2 back cylinder so you have to remove the induction manifold (12 bolts I think) to access the back three cylinders (2,3,6,) properly.
Then proceed as with the front three spark plugs, refit manifold and plastic cover,

The intake manifold is very easy to pull off this vehicle, i strongly recommend replacing the intake gasket when doing so. Cannot find aftermarket repair manual however you can get a ford one of ebay hope this helps

On Ford Escape you have to pull intake manifold Not real bad has oring gasket and is plastic. May be simular FORD charges $600 to do it.

You will need to Loosen the Exhaust Manifolds to get to the Rear Spark Plugs. The Gaskets on the Manifolds will be OK to reuse in the Repair. I Know, It is a Flaw that Ford has not Fixed as of Recent. Please Rate My Response! Thanks!
