Ford 4.2 L Camshaft Position Synchronizer Replacement HOW TO 

Probably one of the best tutorials I’ve seen on RU-vid. Thanks

Extremely helpful video! One thought: Your green alignment mark isn't really needed. It's the alignment of the half-circle relative to the pick-up sensor under the cap that is the crucial position to get right. That's what tells the ECU your camshaft position. Your OTC 6469 tool takes care of that. Of course, though, you want the connector on the housing to be pointing generally in that direction so you can get to it. Dang, it would be nice to have a 3D model of this. It would be a simple part to print!

Excelent video thanks for your help I have 27 year working mechanic and this is the first time what I need install this part and believe me I don’t have idea how instal this part so your video help me too much

Hey thanks For this!!! I watched scanner Danner install one without the tool and I was like there has to be a better way!

Great video. What do you recommend if the sensor is missing and can’t mark it for reference.

😃 When you said first thing to do is pull the engine my eyes got big. Great vid

Excellent detailed explanation supporting a good, clear video. Great job!

Great video wish I wouldn't seen this sooner. If you need a Cam Synchronize Tool and you don't want to buy one you can borrow one at any Auto Zone it's 15.00 bucks and when you take it back you get your money back or you can keep it that's what I was told just took it back the other day it worked well it's a Cardone Cam Synchronizer Alignment Tool Kit 84-8400T.

with that install tool is it real needed to find top dead center ? i have to replece mine on my 3.8L 2004 Mustang. thanks great video so helpful

Thanks for the video i will buy the tool and doit on my own. Because my truck is been on 3 different mechanic shops and they haven't do anything

perfect video and very well explained, thanks new subscriber

I got it changed, however, The new one squeaks louder than the old one. Any ideas?

I pulled mine out and put it back in without really thinking about it luckily my advance timing is still around 14 degrees in live data I used the way the wire was shaped and ran I based it off that but I'll definitely tweak it better when I reinstall my old thermostat since my coolant temp seems to run to cold and I have a weird sound when I accelerate now I'm scared I messed up the gear on the synchro and chipped a tooth on it and it's floating around the oil now

Good video. Just installed a .630 High Lift camshaft and dual valvesprings in my 3.8 but didn't leave a mark reference though. It idles but it doesn't respond to throttle. I tuned it for more fuel and it helped a little but i guess the Sensor is still off.

Thats what I be doing Wednesday ...on my 03 Ford F160 4.2

Very good explanation!

Do you need to pull up the whole synchronizer just to replace the bad sensor?

I just replaced mine is there a common problem with these synchronizers getting oil because even though i changed it, when accelerating to 4000 rpms it makes a squeal and kind of sputters and then it catches

Great video James, that helped me out tremendously. Now go take a benadryl and the rest of the day off.🤧

good video well explained, thanks for the posting it.

What or how will sound or what problems will you get if the it’s not on point ..??? Just had mine intstalled and it has aVERY BAD MISFIRE

Thanks helped me out I was able to pull it with out pulling the intake. EGR was a must though

Thank you very much.

Good explanation especially showing the oil pump drive, but do you know that the mark you made doesn’t matter? The cam synchronizer can be installed in any position around 360 degrees if the engine is at #1 top dead centre on the compression stroke before removing the old one and the engine is not turned. I explain this on my channel in detail.

I did everything just the way you said to do and now my car pops through the carb i went back over every thing a dozen times and its still poping could it be the sensor is bad the car ran great before i put a new cam cover gasket on could i maybe damaged the sensor some how im lost and could use any advice i can get

I installed the cam and synchronizer. However I believe my crank pulley is not where it's supposed to be at. The sixth tooth is in the middle of the crank sensor but the 0 is not in the timing cover arrow. It's off about by an inch. I know my engine is timed. Since I had a professional take care of that. Would I be ok ? Please get back to me . Thank you

Very helpful pretty straight forward thanks

Why harmonic balancer doesn’t have this numbers are marks??!

Very good video

Thank's sir Hpy nice day Bless u

Thanks man! Good explanation

Great vid. Helped a lot. Thank you!!

Es muy necesaria la erramienta para poner un árbol depocision en un motor 4.2

Actually, you need to install the tool before marking it and removing the part, for acute installation. If you remove it then install the tool, it will be slightly off, hence defeating the purpose using the tool.

Very good information , and video ,thanks

So I pulled the thing off without putting on Tdc first is okay? So long as I move to tdc?

Great 👍 video fantastic explanation

Do you have a video of that motor fixing the timing cover seal??

Very very good smart dude

I think 😢this confusing The crank pulley is keyed to go on one way. Not mentioned. 2 Timing crank pulley to TDCwith the degree numbers on pulley is relatef to camshaft position. The crankshaft goes past TDC twice to one rotation of cam. No mention of theory to that. Only mentions air coming out of hose. But the hose has a check valve, and needs to be pressed in to work. Only lets air out of cylinder when connected to a compression gauge and check valve is then opened

What if I'm just changing the camshaft sensor?? Do I still need to pull the synchronizer out?? And the special tool

Good video bro

I took mine out and installed a new one without a special tool and my truck runs great why do people have such a hard time with this???

So 2002 ecoline 4.2 will work on a 98 f150 4.2?

My truck is using lots of fuel and it starts kicking when driving you think it’s my Timing the problem

Do I need the tool just to replace the sensor by itself?

Buenas tardes disculpe para sincronizar un cougar xr7 3.8 son las mismas marcas? no encuentro información en México gracias!!

Awesome video. Thank you

Does the 6th tooth on the tone wheel apply to the 3.8 also?

Great work fantastic 👌

Perfect! 👍

Very helpfull tnx 👍

Great video, God bless you!

good information tanks

Lmao you shoulda seen my face when you said to remove the engine😂😂 scared me

The special tool was included with my position sensor.

Hi,do you have a video on how to remove the timing cover for this exact engine? I'm stuck at this stage.thanks

Cannot for the life of me get the gears to mesh when I put the synchronizer in on my 98 4.0 ranger cant get my hand in there enough to rotate it in

How do you install it if there is no marks on it or on timing cover? Starting from zero?

I bought an engine without a synchronizer in it, how do I install a new synchronizer into it in the correct position if I have no matchmarks to reference?

Imma try the six tooth trick

I’m having a hard time removing the sensor it’s not budging loose upwards

Don't forget to lube it with clean engine oil or assembly lube

Excelente, saludos

Hey kids. Want to run an msd box? Swap in a Thunderbird distributor.

Bro parties to hard on the weekends

Ah man I removed the truck

Thank you so much
