Ford 4.6L V8 Intake Manifold Replacement

Complete instructions for intake manifold swap on 4.6l Ford V8 engine. It is easy! I got new Dorman 615-175 to replace stock OEM part. Each step was relatively easy but there were a lot of steps. Took me 6 hours total for removal and repair. The Dorman part came with new thermostat and O-ring. Also had new alternator bracket as old one could not be used. This part is improved over original OE as has O-rings for all ports so a gasket is not needed. No more leaking coolant. Fits 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009 and 2010 Crown Victoria and other Ford, Lincoln, Mercury V8 motors such as Mustang, Explorer, Expedition, Grand Marquis, Town Car. The 5.4l truck and Expedition should be similar.

I'll venture to say that you maintaining your composure throughout as you clearly did will have resulted in more people attempting this, and succeeding, than otherwise would. (I, who would ordinarily never consider such an operation, have gone so far as to price a manifold... I have even thought it might be a pleasant task if I had a friend of your bearing standing by during the process. I know this much: I sure would like to have a successful operation like this behind me, to brag about!) Thank you.

[@beauregardb6108]

Kent, thanks for the vid. Just learned that this needs to be done to my wife's car, and this shows me that it's no harder to do than the last time I did one, about 1980, on an Olds. The only things I would suggest to you, in this age of phones that are smarter than I am, is to take step-by-step photos, and to buy a bunch of muffin tins. You can use them to hold your hardware, label them with a china marker or grease pencil, so that you put the right bolts on the right holes, and be more secure that you haven't lost any parts. Then you can use them to make corn muffins...I m'self also prefer to label all hoses and electrical connections, but that's just my lack of confidence...Appreciate your posting this!! Of course, it's December in Chicago...Anybody have a heated garage I could borrow for a day? I'll bring all my own tools, even the 8mm allen wrench...

this video really helped a lot and saved me a lot of money I found the manifold on Amazon for 300 bucks the local auto shop was trying to charge me 12 to 1400 for parts and labor took me a few days to get that bracket due to the weather conditions however I did not reinstall the bracket after replacing the manifold there was also another bracket wiring harness in front of that bracket I ran into during disassemble of the manifold bracket

[@Rikkoshaye]

Thank you so much for making this video! Me and a friend of mine had to take apart his Grand Marquis' intake manifold in order to fix a really serious leak. The job was way bigger than anything we've done before and without this video there is no way we would have gotten it apart and back together again. You did a fantastic job of showing every important part of the job, and had a lot of helpful tips too! Thank you!

[@73challenger5031]

Congrats on a job well done, Sir! I want to add a few things for anyone attempting this procedure. If you are going to disconnect the fuel line, start your car and then give your inertia switch(usually in the trunk) a smack with a screwdriver handle which will cut off the fuel supply and the engine will run out the fuel and then stall. Just make sure to reset the inertia switch button when you're done or the car won't get any fuel to the rails. You didn't mention draining the coolant below the level of the thermostat before removing it. If you don't, you and your engine will be wearing coolant. Good tip when purchasing a new intake: make sure the mounting holes have the brass inserts so you can use the original screws. Those self-tapping screws into the ABS plastic is a hideous idea! You know that ain't gonna last long! One last thing. When removing any hardware(screws, nuts, washers) either try to see if you can keep them installed into the component you're removing or at least bag-n-tag them. Leaving them out on a surface can get bad real quick. Imagine the dog or your kids come running through and bump the table they're on and everything goes flying and what you can find is all mixed up! I'd hate to have my project on hold while I have to hunt for hardware at the auto parts store or online or at Pick-N-Pull, of all things!

[@LOLpsyentist]

Started watching this because I had to do the gaskets on my 04 4.6l explorer. Helped me greatly! I found that i had an internal piece of one of the coolant passages broken on my 20 year old stock manifold so I'm about to put in the same Doorman manifold! Thanks for the guidance.

Great video Kent! I discovered a leak recently while changing out valve cover gaskets on a 2000 Ford Mustang GT.

[@mrelectron6220]

AKS the one he had on there was not shit it had the aluminum crossover for coolant. The all plastic models suck and fail. His got fucked up not failure there is a difference. Also Dormans suck look at the plenum the runners feed into on the new dorman intake very small the oem is much bigger it makes a difference in performance. If your seeing failures of the aluminum cross over design at 100K its because some one don't know how to use a torque wrench. My all plastic pos intake didn't fail untill 165K

[@Mega_Mikey]

At 5:30 , on my gf's 01 mustang, that little hose WOULD NOT come off for anything. It had no clips and it spun freely around the metal fitting but I couldn't pull it off, even after all the fuel pressure was relieved. I didn't want to pry it off and damage it so I just kept them connected and set the rails off to the side without the injectors. Thanks for posting this video! Although for some reason the 4.6 I'm working on is a little backwards, the air intake is on the passenger side and the battery is on the driver side.

[@MrWontstopthefunk]

[@BNew-xv4ce]

Ok wanted to ride around a little bit to make certain that the problem was fixed. I think I figured it out, as I said my thermostat would go up high and drop back down to normal and my car would hesitate. I changed out the intake manifold and the problem still persists. I even change my ERG valve, but to no avail. So I took it to the Mercury dealer and they pulled up two misfire codes. Then they proceeded to tell me that to fix this problem it would run me $2500!! On top of that they couldnt tell me Definity what was leading to the miss firing of my vehicle. I was just on the verge of selling it when I decided to change out my spark plugs and coil packs. Lo and behold upon changing my spark plugs I noticed that I had burned antifreeze all down in the spark plug bay. You can see where antifreeze had gotten down into the spark plug base and had burnt off around the spark plugs. Not to mention that all of my coil packs appear to be worn. After changing this my car rides like a beast!! So to anyone who changes there intake manifold which is composite I would advise to change out your spark plugs and coil packs on this make and model of vehicle. Ford, Lincoln, mercury.

I believe the ford modular engines are all metric, thank you for the video

[@charleswilson4598]

You are correct. All mounting hardware on American cars that I have worked on are all metric since about 1985. If you look at a decimal size chart you will see that there are a few sae sizes and metric sizes that are close but most are not. You may be able to fit a standard sae size wrench on a metric bolt and if it is not too tight that combination might actually work, but if the bolt is very tight where you have to put a lot of pressure on it the standard sae wrench will slip. When i started working on cars all hardware was standard sae and I bought a lot of standard size wrenches. Then metric came along. So now I have two sets of tools, one is metric and one is standard sae.

Old cars become money pits . I had both front power windows fixed . The blend door actuator replaced for $1,000. They had to take off the complete dashboard . The part is about $20.00 part . The labor is the problem. My brother has two Prius cars both with about 140,000 miles . Neither one has had any problems so far . I like the car for its size and highway driving . They are very old school cars. Only one wheel drives the car . Very old school. Merc only has 72,000 miles on it .

Had to replace two coil packs so far. The coils are super expensive at auto parts store. You can get all 8 for $60 on Amazon. Too bad you did not see my air blend door replacement video as you would have saved $1000 for two hours work. I did it without removing dash. You should not smell any gasoline so look for a leak in fuel rail area. if you look at how expensive a new car is each month you still come out way ahead with the old one.

Thank you for the video, i changed mine and i followed everything you did. Now it runs great! I think i need to change my air actuator, I think i might be why mine busted. Any ways thanks again and good luck to you in the future :)

just did mine on a 2008 F150 w 4.6L ... I ordered this part # from Amazon APDTY 726486 Intake Manifold .... I do have some mid level experience working on my own vehicles and a good collection of tools... so depending on your experience - you may find this somewhat difficult... It is not a complex procedure, but tedious and took me 5 hrs to complete... I also replaced the orings on the injectors while I had the fuel rails off... unlike this video , 2008 model has a half/ throttle body attached to a plastic housing - I disconnected 4 bolts an just laid it to the side EZ... if in doubt - take pictures of wires and hoses... the only pain in the ass was the drivers side manifold bolt closest to the firewall - the wire harness is laying on top of it ...

Looks similar to Doorman. Suggest you use Ford OEM replacement part. Can order PI improved model from Ford Racing.

[@rts100x5]

are you actually suggesting I take off the one I just put on....send it back and order the much more expensive Ford part and .......... you see where Im going ?

[@KentDiego]

Guess my advice was a little late. I lost a solid 1 MPG by using the Dorman. Wished I spent the extra $75 for the Ford PI unit for exact OEM replacement. Hope yours works OK. Be sure to save the old bracket and bolts just in case....

[@Mmagz6]

Thanks for the excellent video Kent! You showed great patience with this too.. Since this was 10 years ago anyone found a decent aftermarket brand now that we don't have the Ford oem option? I know this is Dorman here. Have they improved any? (96 Mustang GT npi) Not looking to do the PI upgrade yet.

I tried the cut-&-tap fix with a brass fitting and some JB plastic weld. The plastic is too weak to hold. It'll get you by for a very little while, but it is in no way a permanent fix

[@joeyg7447]

Great video! Great patience. Thanks this video was very helpful.

I just bought a new intake manifold and I'm going to do it

[@kennethdurbin3385]

I think mine is leaking in several spots on my 00 mustang gt. It already had the pi intake swapped when I bought it in 2010. Leaking around a few COP holes and just yesterday I saw a huge coolant puddle on the ground above the firewall. Cant see up in there from underneath or on top so gonna finally pull it. American Muscle has them for $249.

Thanks for this Video, My 03 Crown Vic Interceptor has the infamous t-stat crossover coolant leak. I'm gonna try the Dorman intake, cause the original ford part is too expensive. .... Thanks again Sir !

[@rompn4x]

You don't have to take off the alternator. I just removed the top bracket and had room to pull intake up and out. I noticed a smoother idle after swapping the intake on my 03 Crown Vic. One thing you do not want to do is bend the EGR pipe. I did and ended up breaking it...

[@philipdecook7604]

Thanks for the tip on the alternator. I didn't have to remove mine from my 4.6L F150 either and it saved me a bunch of time.

[@Ilusha77]

Thank you for making the video, this helps a lot!

[@Westportnez]

it was my first time but I did it and it worked out for me and saved me some money thx

[@booknikYT]

Don't break anything... THAT SHOULD OF BEEN THE FIRST THING YOU SAID! SHEESH! 🤪

[@christina5664]

same heater nipple broke on mine, home depot got pvc adapter 1/2" to 3/8" JB weld right onto and over that port, good to go, less tgan $6 total and 6hour cure time.

[@KentDiego]

I was thinking of drilling and tapping threads for a brass nipple. In any case there is always an increased risk of having the repair fail when you are in the middle of nowhere.

[@scottk7679]

GREAT instruction

[@davep.6543]

WARNING: if you use an intake manifold with a heater hose outlet on the back, like the Dorman replacement, you will need to change the rubber cap ever few months if you do not use this for the heater hose. these rubber caps will not take the heat. Buy a manifold from ford and it will not be there or will not be plastic but aluminum.

[@KentDiego]

I lost 1 MPG with Dorman. The original factory replacement PI manifold can be bought from Ford Racing at a reasonable price. I was rushed for time so used Dorman.

[@ILikeThemFast]

I have replaced my oem intake manifold on my 2007 F150 4.6L this weekend with the help of this video. However I am running into issues now. The Dorman has a different size and shape of the rear coolant passage that is blocked off, and as soon as I started putting back the coolant once everything was installed, coolant was pouring out the rear drivers side coolant passage...if anyone has any solutions to this, would be much appreciated

[@Motivationthatdrivesyou]

thats what I need to do to my 06 grand marquis.

[@paulratcliff763]

My heater hose nipple corroded off while driving and overheated.
