Ford 4.6L V8 Intake Manifold Cracked or Melted Coolant Inlet Fix DIY

I have a pic.

[@mrshep8215]

This was a great walkthrough , I did this job on my 1998 crown Vic police during the Thanksgiving break (after avoiding the job for a little over a year) , it shocked me how much ease i had doing it thanks to this video. I used a few shortcuts like not disconnecting the fuel line and resting the throttle body to the side after only unbolting it and taking off the two rear houses. I also used a permatex gasket sealer at the top of the thermostat and left it overnight to dry to prevent any potential leaks.

[@encinobalboa]

Yes, yes, five years later. Permatex on gaskets that are exposed to coolant is an excellent idea and will extend service life. There is a gasket underneath the crossover on the top side that fails and cracks the housing. Permatex will prevent ingress into gasket channel and stop coolant crystallization.

[@carlel4219]

You are our man. Thank you for sharing your work with us. Wow so excellently done and clear. I loved doing mechanical work on my cars until I had an accident where I injured my spine and I am trying to size it up if I would be able to do this. It does involve a lot of stretching on your back. Your video motivates me into doing it. It might take me longer. My car is leaking not a lot, but I know I will run out of time. Thank you again for such beautiful work. Stay safe.

[@barrydee587]

Great instructional video. I have a 2000 Grand Marquis that needs a intake replacement and while I have all the tools I lack the experience in some areas. It gets old constantly checking the coolant level and adding to it. You make it look easy. I believe I read there was a recall on those intake manifolds and I may have even ignored it. Hindsight is 20/20.

[@mrshep8215]

I am absolutely grateful that you would take the time time to make and share this video with us. you're the man !!

[@edbreton6693]

thank you for the video. I replaced one of these a few years ago and needed to refresh my memory on the procedures involved. watching and listening to your instructions, for me, far exceeded the quality of the instructions of any written or video material i have seen previously.

[@sc0mer]

Dood! Whoever you are...THANK YOU! I just did this on a 2007 Grand Marquis. Your video saved me so much time. I watched it twice and got the whole job including plugs done in 3 1/2 hrs. Thank you sooooooooo much! Ive done a lot of work on cars and this was actually pretty dern easy. I left that bracket off on the left rear. Didnt seem to do anything. One of the bolts is for the intake manifold so I just put a shorter one in. I think it was for earlier models/different models.

[@50sKid]

glad it helped ya out man!

[@Black8White]

Hey Tom, I am currently doing the same for my 07 Grand Marqui. What did you place on the heated pcb valve ? my old manifold had nothing there, and the doorman manifold has the threaded hole on the metal piece up on the front. Thank you in advance.

[@jaygee6983]

Tom which part number was it ?

[@tommyp8920]

ok. I have been watching you're video faithfully for ~2 months now. Literally every night. I'm finally comfortable enough, and I've ordered my intake. Wish me luck. Thank you for such a great tut.

[@50sKid]

+Tommy Nolips Nice, good luck

[@tommyp8920]

+50sKid Job done. The Dorman alternator bracket provided did not fit, i reused my old one. The job all in all took roughly 8 hours, 2 of those were spent taking everything apart again because i had broken off the thermostat bolt and had to remove the stud from the block. Against your advice, I used Permatex Ultra Blue Sealant around the coolant passages BECAUSE upon inspection of the block, there was severe pitting around the 2 front passages. I figured to use sealant on all 4 so that it would seat correctly (thats my theory anyways). I had put the sealant on the INTAKE side, but after removal to get the broken bolt out, I didn't like how (in)consistent the bead was, so upon reinstallatiion I put the sealant around the coolant passages on the BLOCK side. Don't forget to depressurize you're full system BEFORE removing half the engine.... I didn't have pressure in the lines but there was residual fuel in the rail, which happily spilled all over. The thermostat bolts may be seized in, if it is, pb blast them to get them off. I ended up using my breaker bar to free them. upon reinstall, I greased the bolts and slowly backed them in and out until i was happy i wasn't going to snap it off (again). For that bastard bolt.... a ratchet with a pivoting head is all thats needed. I didn't bother reinstalling it. Thk you for such a great tutorial, you literally walked me through every step.

[@WayneZimmerman]

Great Video, I have a 2004 Crown Vic and it failed exactly the same way this video shows. The job took me about 5 hours, and about an hour of that was just cleaning up the leftover gasket, plus I changed the plugs because it was easy with everything off and out of the way. Used the Dorman replacement part as well. I would recommend using the craftsman max axess for the 15mm bolt on the backside of the engine, it made life so much easier.

[@50sKid]

+Wayne Zimmerman Nice, glad it helped you out.

[@jesselopez7143]

Thank you for videoing your removal of the spacer to stop the leak. I just added a dorman to my crown vic and was worried about what I had done wrong. I had that same leak from the thermostat housing. Awesome video, thanks again!

[@pianoplayer56723]

Ford should have made the entire intake manifold out of aluminum not just one section.

[@DavidHummel-cc4of]

Yes those plastic/rubber baffles,elbows terminals and fittings are built to melt and spill Some old school car makers might be turning over in the grave. Others might be jealous they didn't come up with it. . planned obsolesance.

[@markedward8639]

From what I've read elsewhere, an aluminum intake manifold on these engines suffers from "heat soak", then you have hot air going in, then performance starts to decay.

[@visualmindstv9982]

Facts!!

[@scottflis3925]

Edilbrock makes one.

[@kraigdekoker4679]

Great video, thanks. This was 95 percent correct for a 2001 crown Victoria. Saved my bacon. So the presenting problem was a fluid leak near the rear oil pan of the car. When I looked at the top of the engine block there was coolant on top of the block. I was unsure where the leak was, but after watching the video decided the manifold should be replaced. New one on, and the leak is gone. Appreciate the help. 120k on the car when this went out. I don’t see an obvious gasket problem, but i suspect the plastic is warped.

[@stevep756]

Kraig, how bad was the leak? My 2011 CVPI,140K miles, just developed a very small leak that would drip when not running. Only see it in the front along the oil pan gasket. Top looks dry and don't see any leak by the water pump at all. Thanks Steve

[@johnlarock4486]

@@stevep756 There's a line to the heater that comes out of the back of the water pump and runs under the manifold, I'd replace that at the same time as the manifold or you'll end up doing it twice like I just did. It leaks into the valley between the cylinders and drains through the bellhousing, you really can't tell where it's coming from by looking underneath.

[@brandoncraig6135]

Now this is a tutorial video! Thank you so much for the tips, clear explanation and slower pace. It helped me so much. Keep up the good work!

[@jamesdonovan7946]

Good video You might just mention in the beginning of your video to drain coolant and disconnect negative battery cable. Also if you use a little silicone spray on the fuel injectors O-rings to make it easier and not roll the O-rings off The use of anti seize on bolt threads and EGR pipe nut will help if you go back latter for repairs.

[@THEGAME-tz6yu]

Great advice,i use anti alot .thread sealant is good also.

[@badopinionsrighthere]

16:50 important note: the hard bolt is pointed towards the firewall. Not standing up. THAT bolt is a royal pain to remove because a socket wrench won't fit very well and doesn't need to come off yet. the bolt for the bracket is fiddly, but not as hard.

[@ViciousAdventures-ls2em]

Dorman makes a great kit for this application. Smear a bit of fresh motor oil on those injector rings so they seat easily without rolling... Don't ask me how I know. For those looking to maintain max performance, get the OEM Ford part. It's more expensive, but the longer runners are good for at least 17 HP in the upper RPM range. Sadly, they're getting harder to find.

[@MrKaddyman61]

Nice to see some actual trouble shooting as opposed to a perfect install. I'm doing the same on my 2008 CVPI, my gasket failed. Was able to order a new manifold on partsgeek cheaper than other websites.

[@charleswilson4598]

That stud with the nut that you were wondering about is for a cable bracket that is bolted to that stud with a 13mm nut. If there was no 13mm nut or bracket it is because somebody failed to replace it. You can remove that stud and the crash bracket as you have shown here, but I decided to remove the windshield wiper shroud which then exposes that hard to reach bolt and makes it easy to reach. The shroud is easy to remove and takes 20 - 30 minutes of easy work. But my approach is to remove things that are in the way instead of fighting with them. Most people would probably work around it like you did. I replaced the manifold on my 2001 F150 and my Daughter's 2000 Mercury Grand Marquis.

[@displayfireworks1]

One of the better videos on KZbin about how to correct this issue. My 2003 Grand Marquis had this issue, luckily there is local guy near me that does this job. Cost was a little under $500.00 total. He does this on all the local police cars. LOL I would hate to think how much the Ford garage would charge.

[@twistedguy4106]

Mine split on the tube that's on the passenger side rear I used jb weld yellow in color 5min set time an it worked like a charm I also used it once on a bullet hole in my radiator but with fiber patch as a structure an 4yrs later still works great not a problem at all

[@elppedro77]

Well done video, but at 19:09 removing the fuel cap will NOT relieve fuel pressure! You have to remove the fuel pump fuse while the engine is running to relieve the pressure. Once the engine dies due to no pressure, then turn off the ignition and replace the fuse (or wait until you finish the job) in case you need to work the windows, locks, or listen to the radio, etc. Remember each time you turn the ignition switch to "on " the fuel pump will work even if you don't start the engine.....

[@charliedee9276]

ATK also makes a replacement manifold that unlike the Dorman is an exact replica of the factory design. Dorman changed the intake runners which kills some top end power. Good video.

[@1972mercurycougar]

Nice job While your in, under the intake, in front on driver side cylinder head, replace the cylinder head temp sensor, and wire plug, if need be. Especially, if a mild over heat happened.

[@TheCottonTop]

Note: Pull manifold first, unless you just like leaning over a hood. The throttlebody and fuel rails will be much easier to manage once out of the car.

How long did this take you overall? I just bought an 05 town car with 179k and discovered some bubbling behind the aluminum part on the passenger side right around where that first injector is so I just went to summit and bought a new intake and heater tube since it will be apart anyhow

[@bybeyer6490]

thx for the video, how can I quickly tell whether the intake manifold needs replacing (or is about to)? Looking at used Panthers and i don´t want to buy one where I´ll have to replace it soon

[@50sKid]

+by beyer Look for signs of coolant leakage as I point out in the beginning of the video. Also check for an all plastic manifold without the aluminum cooling channel, that signifies that its the OEM one. But then again, the later models have the upgraded part with the aluminum cooling channel, so, it's tricky.

[@m.n.3490]

I just finished this job on my 97 grand marquis, and your video helped a lot. Thank you. I have a question about the drill tool you were using. I tried to loosen, and tighten, my bolts with two different drills, and neither had the power like yours did. The drills I had access to were a ryobi 12volt lithium drill, and a Dewalt 20 volt lithium drill. I cannot find any spec on torque for these. What drill are you using? What spec should I look for? Volts? Torque? RPM?

[@tommyp8920]

This job is the same for a 98 town car, except for the bastard bolt on the fuel rail crash bracket. The cowl is shaped different, and isn't as forgiving for space. Regardless don't even bother wrestling the bastard bolt from the side; you will have to take out the wiper assembly and front cowl, because there is a plate with harness attached to the bastard bolt with a nut in front. I managed to use an open ended socket for the first nut, and had to bend the plate a little to be able to slide a wrench in to turn the bastard bolt. Like I said the video works for a crown vic, but for a town car there is a little more disassembly. Hopefully this helps someone!

[@50sKid]

Nice, thanks for the additional info.

Yep Tommy the CV and GM owners don't know how lucky they are been there done that too

[@Ian2565a29]

This manifold has been replaced prior to you or at least the wiring in back of the engine was moved around or disconnected for some reason. The annoying stud bolt was for an additional, seemingly unnecessary bracket. When I reinstall, I will probably not install the bracket to the stud

[@phillipt6]

I personally just bought a mustang GT 2002, with 91k and some change on it, come to find out that they had put a new motor in it from jasper. I'm guessing that the engine failed because of this, but there was no documentation from it.

[@johnnystephens6329]

50's kid, as they say, there are many ways to skin a cat. The throttle body with cables can just lay over to the side. Eliminating taking the cables off. Also I left the alternator on and just wiggled the intake out, it wasn't bad getting past the EGR tube. Just don't get carried away and move your gaskets. Check them before you bolt the intake down. Same thing with the fuel lines. Leave the fuel lines hooked up and set the injectors and rail off to the passenger side. Maybe these ideas may help you in the future

[@98snakehorse]

If this is going on a car that is just a daily commuter the dorman intake will work just fine. However these units are not a good replacement for the mustang platforms as the intake runners are much smaller and rob hp&tq to the engine. They also have issues with the ports not being big enough to get a socket to change the spark plugs.

[@Driftking-dd6wx]

About to do this tomorrow to my 2000 mustang gt hopefully I don’t have to buy a new intake manifold just the gaskets but we will see !

man my 04 mustang gt literally started leaking from the bottom of the aluminum crossover thermostat housing, i heard the this is a notorious issue, also the nipple on the rear passenger side of the intake where the heater hose connects to, shattered on me lol. I managed to fix that (long story) but was just searching around seeing how exactly people went about changing the manifold etc. Even though there are slight differences between this 4.6 and mine, the information you gave was very applicable. Yes i actually watched the whole video lol, gonna tackle the job tomorrow morning see what exactly is wrong. Either way great video dude very helpful, Thanks!

Nice how-to video, I think the intake on my 06 Crown Vic’s 4.6 is leaking in the rear at those coolant passages. My most rear spark plug wells are getting coolant in them. I’m adding about 1/4 gallon of coolant every 300 miles now...

[@neilouellette3004]

Yes, it's the intake manifold. When coolant is getting into your spark plug wells, it's this manifold.

[@scottdillon1337]

it doesn't matter where each coil goes back, but good video

[@jimmyh8934]

The reason why that has a stud coming off of that most difficult bolt you took off is because there is another bracket that goes there...someone may have left it off previously...on mine didn't have to remove alt...I just tilted manifold up to remove and install...

Would a leaking gasket on the 4.6 (I have an explorer) cause you to see anti-freeze dripping from between back on engine block and transmission, dripping onto transmission drain pan bolts (Freeze plug maybe)

[@lowdenzacry]

Check the nipple on the back of the intake that connects to your heater core maybe a lose hose or the base of the nipple has a crack

[@aaronrodden8121]

Most likely, it's a crack on I take and it usually travels backwards (front of vehicle to rear) and drains down between transmission housing and engine (where they meet) so yes, most likely it's the intake manifold or something under the intake manifold (i.e. heater hose, thermostat or something along those lines) so you probably do have to take the intake off just to find the leak and fix it!

[@aaronrodden8121]

Also, the 4.6 tilts to the rear of the car and has a V valley and and a drain port (of sorts) in the middle hence the leak right where your saying!

[@encinobalboa]

I appreciate the effort to make a video. However... Do not remove EGR. Tube can be brittle. Intake will slip out underneath. Dorman is trash. Dorman is for flippers. OEM is for owners. If you can't afford OEM, be sure to apply RTV to the surfaces around water passages. That will stop coolant from crystalizing on the gasket and in the gasket channel. Crystallization expands the channel and causes cracks and leaks.

[@50sKid]

jyg101 No i'm afraid not. If you have the newer manifold that already has an aluminum coolant bypass channel, it is bolted into the black plastic manifold from the bottom. That's why there is a little layer of black plastic between it and the cylinder head. The bolt is recessed in that little later of plastic. And that's where it cracks. It's almost always the manifold that cracks, btw, but it could be the gasket. No way to know until you get it off. Good luck!

another question: 01 grand marquis, 78,000 miles. my leak is back of engine below gets a puddle on ground see dripping down by bell housing and oil pan. i don't want to buy the manifold if the leak is from the metal pipe in the valley area. i don't see heater hoses leaking. saw video guy rechannel the metal pipe due to leak from the valley under manifold to above engine. is there a way to determine where the leak is originating from without remove the manifold i.e. metal pipe? if it was a metal pipe and i want to re route the pipe with a heater hose above engine how would the rubber hose be attached to the water pump area in place of the metal pipe? i wrote the guy on youtube but he did the work 5 years ago so he may not even be on youtube. i get no answers from him or anyone on that cite. any help on figuring if it is manifold. i did see small puddle below the muffler pipe after running car and letting to sit for awhile.

I have 2008 Crown Victoria and I had a PO307 code # 7 engine misfire. I thought it would be a simple fix just change the ignition coil or spark plug and I'm good to go. unfortunately that was not the case, I found coolant around the ignition coil boot. I know the intake manifold is the problem. My question to you what are the chances of a bad gasket and not a cracked intake manifold on 2008 Crown Vic P71 with only 96,000 no including the idling hours?

[@50sKid]

As far as i know, the chances are low that it's the gasket and not the manifold. The manifold is the weak link.

Hello good videos. I got questions about swap engine. is about expedition 1998 4.6. what's ford models use the same engine and years?

[@EarlGuyton425]

Why not just buy the full aluminum intake for the 4.6 thats used on ford f150s?

[@charlespatton8952]

What tools do I need for this job?

[@felmypeto1]

Thank you for your video, I had the same exact problem on my 2005 Mountaineer. What a poor design by Ford.

great video I appreciate all details thank you sir

With the intake gasket leaking will that cause it to overheat

[@DeestarMusic55]

Yes

[@chadbeen6232]

Will this gasket make coolant leak off the back side of the engine?

[@50sKid]

Yes skip to 23:58 of this video, you can see the three brightly colored passages at the back of the engine. Those are coolant passages. Another 3 on the front of the engine as well.
