You are watching: 2004 ford taurus spark plug replacement


Hello,For the Ford Taurus 2004 SES with Duratec 24 valve DOHC engine (with 80k miles) (please see the picture), it seems that 3 of the spark plugs are underneath the upper intake manifold. I have hard time finding a video or manual to guide with minimum removal of parts to safely and without damage to reach the 3 hidden spark plugs. Any help is highly appreciated. also let me know if I should change the wires.Best regards,Mansour:usa:
No wires to change. Coil on plug, COP. Why are you changing the plugs? Do the ones in the front look bad? The originals last up to 100,000 miles. If they have already been changed leave them in.

I have done this 6-8 times, intake off that is. Coil, plugs, redo plugs and such. Remove the intake is just busy work and keeping all the parts like bolts/nuts safe. And I stuff paper towels in each intake to avoid dropping things in there. Good time to do the PCV, had one stuck at 100K. Stuck closed. Never replaced a gasket, no issue except forgetting that vertical vacuum hose noted that I replace as routine. And I know you have COP"s but the idea is the same. Intake remove takes me about 20 minutes, but I am old and slow. You may uncover vacuum hoses that need help at the same time. Best remember to hook them all back. -chart-
Egh, its different than mine but watching youtube videos gave me confidence to do this job. Most of the engines are close enough you can figure it out. Took me 4 hours the first time (I went slow and carefully and spent quite a while totally cleaning UIM mating surfaces) and now I can blow through it in 10-15 minutes.
There are other videos on youtube as well, maybe even one for your year/model.(Your car will sound like a jet plane if you forget that vertical hose next to the PCV under the UIM! heh)If you have specific questions those would be easier to answer than such a broad one.

I wish you had made a video for the replacement. There are no problems for the front 3, but the rear ones are difficult to reach. Also, the videos seem to remove too many parts than needed? Is there a way of replacing them without removing air intake?
I heard from a mechanic sometime ago that there was a way of reaching to the rear spark plugs without the hassle of opening in the upper air intake. If I remember correctly, he was saying that it was from the passenger side, Any comments will be appreciated.

You might be able to reach them but from my experience it is far easier and less frustrating to just remove the UIM. It"s not as difficult a job as you might think.

On 04 and 05 Tecs you MUST remove the upper intake. Without removing it, you can not get the COPs off to get to the plugs.

Thank you for your information. Considering the need to change the PCV valve as mentioned in the second PDF file, I am getting the impression that this is a design flaw. I checked with FireStone and they quoted $540 to do the job. This is very sad that a company does not make enough effort to help the owners maintain the cars in a cost effective fashion.

I could do the plugs, PCV, and hose in an hour, and I am 76. I have done several "01 and"03. And I do the plug wires too. It is just busy work. And by the 100K mark, you need to inspect all the hoses too. -chart-

The fact that one company charges a preposterous amount for a simple procedure does not constitute a design flaw on the part of another. We are talking about a fairly straight forward maintenance procedure that on average will be done once in the life of most Tecs, as is evidenced by the fact that it is 12 years old and you are just becoming concerned with it now. Someone with no experience and moderate aptitude can expect the job to take no more than 2 hours. I would suggest pricing the job elsewhere or picking up some tools.

Book time for 2004-2005 spark plugs is 2.6 hours for the back and 0.9 hours for the front or 3.3 hours for all 6. They can add 0.2 hours to all of those times if the time category is "severe".Add 0.3 hours for the PCV.Most people will charge $400+ for the job but yeah, the Firestone quote is a bit high. Some shops may have a PCV book time that includes removing the UIM so may double charge you for UIM removal when you get a quote for spark plugs + PCV. Some may mistakenly quote for spark plug wires.

Some may mistakenly quote for spark plug wires - 1 hour labor plus parts.Most other Taurus have a book time of 1.3 hours or less to replace all spark plugs, so yes the design change for 2004 onwards was a bit dumb.

9 minutes maybe. My niece"s "05 had a bad rear cop (cyl 2) so naturally I replaced all the plugs while I was there. I was done in less than an hour and 15 minutes and I have a bad spine that entails my getting upright and walking away for a moment every 15 minutes or so. As far as dumb goes, again, we are talking about something that will happen once in the life of the average Tec.
