V-6 answer: Standing at the licenst plate. Remove the plastic shroud on top of the engine (closest to you) and unbolt the metal box directly below it you can gain access to …the front three. As for the back, remove the connector and screw at the 7 o'clock position off to the side of the dist cap. You CAN reach the back three with two 6 inch socket extenders and without remvoing any other engine parts. Should take 30 min regardless of experience. I just did mine and I'm not a mechanic (06/27/07). Hey, I'm not sure if the answer involving removal of the valve covers, and appearently everything else in the engine compartment, is misleading on purpose but...... all you need to do on the 4 cylinder Cougar is pull the wires out by their bases and use a long exstension on your socket. I'm not sure what this guy was trying to do but I hope not too many people followed his advice!! The answer from Greg was exactly correct. To remove the spark plugs, remove the covers and you will see how simple it really is. The spark plugs are hiding under the covers. Greg Hasen Not only you will have to lift the covers, but to reach the back three you will have to remove the valve cover. Here's how to: 1. Remove the water pump belt cover (the black cover in the front of the engine compartment that has ?Duratec? on it.) If you have a 1996+ vehicle, you should think about removing it permanently, since it only serves to trap heat and slowly kill the IMRC box electronics. 2. Disconnect the following electrical connectors from the: MAF, IAT, TPS, IAC, and EVR. The EVR connector is black and is located at the very back of the upper plenum, next to the firewall. 3. Disconnect throttle cable from the TB and the cruise control cable, if equipped. For 1995 5-speed vehicles, take care not to lose the metal clip for the throttle cable when you are removing it. Once the cable is removed the clip will slide right off. 4. Disconnect the vacuum lines from the EVR. You may have to wait until the upper intake is unbolted and partially removed for better leverage. 5. Disconnect the vacuum lines from the top of the upper intake. Push down on the black plastic collar with a screwdriver and hold, and then pull the plastic line out of the intake. 6. Remove the air box along with the MAF and accordion tube. 7. Unbolt the throttle cable bracket from the upper intake (three 8mm bolts, one 10mm nut). Set bracket and attached cables aside. 8. Disconnect the air bypass hose at the upper intake. It connects right next to the IAC valve. 9. Disconnect the hose from the PCV valve that goes to the upper intake, underneath the throttle body. This is also a good time to change the PCV valve. 10. Unbolt the EGR valve from the upper intake. 11. Unbolt the upper intake. 12. Carefully remove the upper intake and set it on top of some clean rags or newspaper. It will likely be oozing some oily gunk out the bottom. 13. Cover the openings of the lower intake with clean rags to keep anything from falling into the openings. Anything that falls in will likely end up in the head or the cylinders themselves. Now you are free to remove the back plugs. Jesus
Answer . This information can be found in your owner's manual, or under the hood on a placard. If you do not have one, then you need to get one. Dealer, E-Bay, Salvage Yard…, and many online sites are sources for a manual. Use Google and search with the term, "Automobile Owner's Manual".

Use a 1/4" ratchet, 4" & 6" extentions, swivel, adapter, and foam filled spark plug deep well socket. Use the combination of these tools that feels right for you. The extentio…ns will be primarily for the three rear (closest to the fire wall). Most mechanics will say it is necessary to remove the plenum. This is NOT true. I changed my plugs without removing the plenum and using these same tools. I still had the original (OEM) plugs wires and chose not to replace them. You can replace with OEM purchased from dealership for about $250, give or take, or replace with after market wires. Job complete about 1.5 hrs depending on you.
Answer . You fail the mention which engine, so I will assume it is a V6: Look here:. http://autorepair.about.com/library/firing_orders/bl-fo-4103.htm
Replacing the tire on a 99 mercury cougar is fairly easy. Jack upthe car, remove the rim bolts and the tire will come off. Put onnew one and reassemble.
same way as you replace the front three. You may need to move 1 or 2 components to access them, and you will probably need an extention and universal joint, or wobble joint.
.52 - .56 Only use Motorcraft or Autolite plugs or your car won't run worth a crap after a couple of weeks. Assuming you have the 6 cyl? Duratec engines in the Cougars are not…orious for not liking other brands.
One at a time... Here's a step-by-step guide for your car (make sure it all goes on one line): http://www.autozone.com/addVehicleId,1612301/initialAction,repairGuide/sho…pping/repairGuide.htm?pageId=0900c1528006b415#hd1-1-2 Have fun!

break off the old ones with a sledge hammer and drill out the stubs with a roto hammer. now pour some epoxy in there.. let it set for three weeks. now sand insides with a drem…el tool and install new plugs, youre all set
take the upper intake off then you can get to the plugs good New Answer: I had trouble getting access to the rear plug wires and trouble getting a plug threaded once I got o…ne out. I removed the plenum, about six nuts, to get better access to the rear bank . Nothing mysterious, leaking, or needing new gaskets under the plenum. Was able to get the spark plugs in and out that way.
repalce one at time with new one until all replace to make the wire are back in the right place
