Ford Crown Victoria Spark Plug Change

[@gustavbabic5004]

If you're not familiar with changing plugs on the 4.6, I recommend going down to the local wrecking yard and practice on an old police car or taxi cab they got sitting around there. Also, be very careful when removing the coil from cylinder number eight (last one on driver's side) because it is very easy to strip the head of the bolt holding the coil down, and it is also a little bit tricky getting the coil in and out of that location. Also, if you're new to this, I would recommend doing one spark plug at a time. Also, when putting the new spark plugs in, I recommend using a length of 3/8 fuel line instead of socket and an extension. The 3/8 fuel line will grip the ceramic insulator tight enough that you can screw it in, but it will slip if you start to make a cross threading mistake.

[@Chaos_]

Good advice!

[@davidyoung8521]

The fuel line trick goes way back. You can't cross thread using hand power. You can feel the thread catch.

[@Mikol_Billy]

It’s obnoxious how clean your engine is

[@mteachwo]

Thanks for the video. I recommend to remove and replace only one plug at a time. With all 4 plugs out at the same time like you did you can accidentally knock dirt down into one of the open spark plug holes while you are working.

[@corey_roberts7671]

mteachwo that why he cleaned them off first

[@roystump6676]

P pl lqq

[@davidyoung8521]

One at a time.

[@dowbuford8468]

I really appreciate being able to see how you accessed and removed all 8 spark plugs. The other videos I had reviewed only showed one or two. Thanks much,

[@theckblood]

i have tightened my own spark plugs down with my own strength and on warm engines for years and years. on all types of fords. from 5.4 expedtions. to broncos with 0 problems

[@RPSNDRS]

P71 mechanic Gilum what size socket? I'm using a 5/8 on my 99,just feels like it's spinning in either direction. Cylinder #4

[@charleswilson4598]

There are many you tube videos showing how to deal with broken plugs on these Ford v8's but they usually refer to the three valve engines not the 2 valve engines. The 2 valve engines seem to have a problem with blowing spark plugs out of the head.

[@charleswilson4598]

You might have been lucky. A lot of these engines are reported to have problems with spark plugs blowing out. That wasn't a problem with the old 352 or 390 but this is a different year, different engines. Even experienced Ford techs say it is a good idea to over torque these spark plugs. Maybe by doing it your way it is normal for you to over torque your spark plugs which might work ok on these engines. Not to mention the great idea Ford had to use plastic intake manifolds which have an unacceptable failure rate.

[@uhsenli6424]

if you tighten them too tihgly you're going end up messing with the gap

[@soloban81]

Thanks for this video - I just did this job on a 2005 CVPI. The tip about the air gun to blow out dirt and debris is spot on. Changing the plugs made a noticeable difference in how the engine was running. Prior to the plug change it was throwing a P0307 code so #7 may not have been firing or only sporadically. Definitely recommend using a 1/4 ratchet to remove the 7mm bolts from the coils - I didn't have a 1/4 joint so I had to use my 3/8" ratchet and it was a PITA for #7 cylinder.

[@2006Mercury]

I always use anti seze on the plugs and lower them onto threads and turn left untill i can feel the threads and make shure i dont mess up the threads. Always just thightened them to tight but not over tight. I always use torq wrench on everything but i dont think the plugs need it. Didnt use a torq wrench on my trans pan bolts. Just didnt over tighten

[@ivancedillo8]

15 newton meters or 11lbs of torque is to low these 4.6 engines, a spec that has been updated to 20-25 ft lbs of torque. Otherwise you risk the plugs popping out, literally, it has happen and it’s a known problem with all 4.6l motors.

[@mediaguy4037]

Everybody usually does 15.

[@SlikLizrd]

Man, you're tempting fate with 20-25 ft./lbs of torque on an aluminum cylinder head. Over 250,000 miles on our 4.6 Romeos at 15-18 ftt/lbs (Using Craftsman "Clicker" Torque Wrench) with never a stripped thread OR a loosened plug. HOWEVER, I NEVER use anti -siezeon my spark plugs, for just one very simple reason: It's too easy to accidently let just a bit of Anti-Sieze get on the gap, which shorts out the plug on start-up. Consideirng the difficulty of accessing the plugs on today's engines makes it too risky, especially on transverse V-6s. TO avoid the dreaded Anti-Sieze, I use Bosch Double-Iridiums, which are plated. Denso also makes fine spark plugs, and they are plated, as well. 20-25 ft/lbs is on the shaky side, in my view, and I'm picky, picky, picky. ;>)

[@tomcervenka7404]

@Chuck Hallowell Stop confusing rookies! I'm taking power techs information.

[@theckblood]

i wouldve took the entire throttle body off. because you can clean the gunk out of the throttle body while changing plugs.

[@keithclark8030]

Okay, now that you are done with yours, you can come do mine...haha. Great video.

[@SlikLizrd]

There is no "debate" !! DO NOT USE anti-seize compond of any kind, the reason being that all anti-seize compounds conduct electricity, and a stray bit of anti-seize on the plug gap will short the plug. I recommend Full Synthetic Engine Oil as a plug thread lubricant -- does the job with no chance of shorting out the spark. Bosch Iridium and Denso Platinum plugs are plated, and there is no need for anti-seize with those brands. The Motorcraft plugs are servicable, but the Bosch Double Iridiums are a better design, and offer better performance. Yes, they cost more, but are WELL worth the money !

[@kccodex8931]

Sounds like a lot of speculation to me.

[@SlikLizrd]

@@kccodex8931 Speculation !?? How so ??

[@baird5776mullet]

Great job on the video,just wish you would have let us hear the cold start.

[@ArmedGhost]

No dielectric grease needed? I have seen some use it before re-installing the coils.

[@kenrivers9757]

Warped Wackos i suggest using it, and anti cease on the plugs.

[@usethenoodle]

Thanks for the video! Its on my to do list for tomorrow.

[@WJHandyDad]

Do you have a link to your source for the "don't use anti-seize?" It seems that if you ask 100 people you get 50 that say use it and 50 that say don't. But I have yet to find anything official from Ford.

[@uhsenli6424]

ngk doesn't need anti seize, any other brand you may need it

[@nickseulovski]

Doesn’t matter on the brand of plug if u never want the plug to seize then use it when u don’t use it there is a small chance. I’ve done both ways and never had a problem either way

[@mediaguy4037]

A little tiny dab on the threads won't hurt anything. As long as you torque them right.

[@gtaelement137]

Thank you for your help change the plug was helpful

[@davidyoung8521]

The back plugs have always been a bear on a V8. Back in the day when the Big 3 would shoehorn a big V8 in a little compact car. Sometimes, we had to take the engine mounts off to lift the engine to get to the plugs.

[@davidyoung8521]

Drilled holes in the inner fender to get to the plugs.

[@Leo-zf7ne]

Called a shop, asked for a tune up on my 2005 Ford crown vic p71. [ idle was acting weird. Bouncy.. while warming up car or at stop lights] was told that it needed new spark plugs and possibly ignition coils? And for this I will pay 289.99. I thought a tune up ment more then jus spark plugs. Thoughts?? Thanks .

[@Yophillips3272]

If You can change the plugs for $20, why the heck would you pay $290?! My cars doing the same thing I'm just going to change the plugs first because it's cheaper. For $290 you could probably change the plugs, coils and air filter and oil change.

[@gtamonkey3061]

Toad Phillips lol exactly, do it yourself, even if your aren’t mechanically inclined changing out spark plugs are the easiest work to do on a car. Great for beginners and saves you money just like changing your own oil.

[@pilgrimpassingthrough2228]

Great video and very complete! Didn't take you very long either! Show off! Just kidding! Thanks!

[@BBT609]

Is there a special orientation on how to put the spark plugs in?

[@SlikLizrd]

YES !! Spark Plugs are to be inserted into the cylinder head with the threaded end going in first.

[@MarcoTheCarGuy]

Damn didn't even check to see if they were gapped correctly... savage 😂

[@ArmedGhost]

Did you watch the video? He said he already gapped them. 14:46

[@MarcoTheCarGuy]

Yea saw it when i rewatch the video to change the plugs on my crown Vic , i guess I missed heard him the first time and I thought he said they were already pre-gapped, but too lazy to delete the comment 😂

[@MarcoTheCarGuy]

Jamar Jackson when I had the car at idle I notice it was much smoother than before and far as acceleration I could tell much cause the torque converter was bad currently doing a transmission swap with a slightly higher stall from 2400 to 2600 to see if helps the launch from dead stop

[@Tomtom62]

Don't the plugs break when u take them out ? i have a 05 and i'm scared shitless of breakin one off. anybody have any tricks ?

[@SlikLizrd]

Plug threads release best when the engine is SLIGHTLY warm. Use the proper size plug wrench -- and remember -- "Lefty-loosey; righty-tighty!" When installing new plugs, use a good-quality torque wrench to be SURE that all plugs are seated properly to maintain maximum compression in each cylinder. On the 4.6 Liter's aluminum heads, I recommend a 150 inch-pound setting on the torque wrench.

[@n.b.p.davenport7066]

Nothing on the threads no anti seize or Loctite?

[@domramos1563]

Can you PLEASE tell me ALL the tools I need,I've never done spark plugs and keep getting confused😵. Please please please PLEASE. And I've watched your video like 5 times

[@twinsonic]

If you are still confused after 5 times, get it done by a mechanic..

[@mediaguy4037]

I'm doing 15 foot pounds so they don't blow out.

[@lebrone4621]

Great video!!!

[@BulletSpoung]

I like using a small amount of copper anti-seize on the plug threads so they don't get stuck in the head.

[@Anythingautomotive]

BulletSpoung if their changed regularly then they shouldn’t seize.

[@kccodex8931]

Absolutely, you'll have much less chance of pulling the threads out with the plug. The change in the torque setting is nominal and not enough to worry about. I've been doing it for 45 years without a problem, ever. No torque wrench, somewhere between snug and good and tight. This younger generation is paranoid. I've seen them use a torque wrench on drain plugs!

[@JCGascon001]

14:29 super info tks

[@hasanalzaabi]

Whats the socket size ur uaing to losen the spark plug?

[@jgwalling]

5/8. Spark plug socket

[@keithclark8030]

Another video said to set torque to 22 instead of 11. Claiming it would keep it from blowing out. Any thoughts from anyone?

[@tinytim9453]

22 lbs seems excessive, I did 15 lbs. I wouldn't go pass 20 lbs. Keep in mind the 4.6/5.4 heads only has 4 threads down in the spark plug wells.

[@tomcervenka7404]

I hear 22-25

Please point the camera at what you are trying to show, instead of above it. This allows the viewer to see what you are talking about. I put the same Motorcraft Platinum plugs in my Crown Vic two months ago, I have had 3 coil packs die since then. How has your car been since your change?

I agree with Derek bad coil pack

[@dylanstevens8542]

Coil pack? How could it possibly be the coil pack of its isolated to just 1 cylinder? Move the coil on cylinder 8 to another cylinder and see if your misfire moves to that cylinder, make sure to clear the codes before u do that.
