So how do you replace the vacuum line that goes through the firewall when it broke off from inside the firewall

So, what happens when you build a car with more computer power than the Space Shuttle? Just because you can do something with a computer, doesn't mean it's a good idea.Cars used to have no computers at all. Solution? Rip out all the wiring and get a street rod wiring harness. Eliminate all the auto-crap. Switches and cables worked just fine.

Whats the name of the sound wand set up your using sir ?

Just get an old spray bottle with soapy water and spray it on the various connections looking for bubbles once you've pressurized the system

Thanks pop's

Excellent video. Helped me figure out it was the switch on my rear passenger door.❤

the best instructions, thank you

Just curious shouldn't you have pinched off the engine vacuum and the line running to the reservoir to narrow it down to the line it ended up being? Your gauge shouldn't have dropped because you still had engine vacuum when you blocked the reservoir. Regardless very helpful video thanks for taking the time to make it.

Yes, the absolute best video on this subject . Hope it helps with my problem. Thanks !!!

Thank you grateful for that knowledge I think that was great because you're right the scanner won't tell you thank you for sharing I'm grateful for it

My car never drived good. only 2 days, no body can help me, is a old car. I put a new sensor and in only do 0.01 volt peak to peak :(.

can i do this with my 2000 ford expedition 5.4 v8? by removing the ignition coil one by one while it is running?

how do I download the pdf? can not find a link to them.

Thank you sir, that was a simple explanation of how it works quickly in my situation while away from home.

First time doing this is it not important for the teeth on the ring gear to be in the exact same spot as the old ring gear?

I've have code PO442 and P0456 for a while now. I replaced the purge valve, Evap canister, EGR valve and gas cap. Still can't figure it out. It is a '10 Forester. Any suggestions?

WOW!! WAT AN ENTRANCE!! All the kids came running cuz they thot I was putting a movie on!! 😂

Hello dear man! I am writing to you from Russia. I have a Dodge Nitro 3.7L automatic transmission 42 rle. I lost reverse speed, sometimes it’s there, sometimes it’s not. please tell me what is the reason for the lack of speed? I will be very grateful to you.

bad that you changed belt and pully before getting out the stethoscope. Ripoff!

I am sure the bird is dead by now, thus is 4 years old. But a trash can lid and a wrench should scare it away. Sounds like it is 3 feet away !

Very smart. In another life in service to a scientific laboratory we chased leaks in our oxygen,nitrogen argon or what ever gases which were piped into the laboratory. We used Mr Bubble children's bathing liquid .cit is semi stick and form bubbles which can be easily seen. We would dilute it ( don't recall the dilution ratio) with water and used a spray bottle. Worked great!

Great video Sir!

So. I have a 2007 Dodge Caravan. The RAP system does not stay on when I shut tge vehicle off. Also, my radio no longer works while driving. Could this be a relay issue or something else. The stereo is an aftermarket Sony deck which I've had for 20+ years. It worked fine but doesn't now since tge RAP system issues. Suggestions?

I didn't have that much trouble putting it in underneath my Dodge Dakota all you do is make sure your liver is all the way over to your passenger side when you hear it click then you can start taking it a loose and taking it down it should drop just like a baby a newborn

How many PSI is acceptable on shop air?

Tell them birds you are videoing and to be quiet

I'm going to try this on a 2007 Saturn Vue Steve C

Thank u

this is very professional (MTM),I have watched your videos for years , Im glad to have found you videos and teaching, I have made a donation. I will subscribe t o your channel

thanks

This happened to mine years ago, pretty bad sound that might make a guy think the bottom end is falling out of the engine! Can happen to any harmonic balancer that uses rubber, but seems a little more common on these.

I know this was posted a decade ago but I wish this could be reuploaded in atleast 1080p. This series has been very helpful.

I've been watching mickey mouse fixes bit this is exactly what I wanted. A 100% fix and it's pretty simple 👍 tysm for the educational video!

Much appreciated.

What if you have no air flowing from the front vents at all? I don't notice any airflow on any fan setting, AC, heat, or defrost. Has it still defaulted to defrost? I have replaced the 3 AC fuses under the steering wheel, the blend door actuator relay, the blend door actuator, the blower motor, and the resistor. Still no air flow. 2001 excursion 7.3 2wd. Rear ac blows cold. No air flow at all to the front. I'm going to try this vacuum diagnosis and see what happens. Best video I've ever seen, great teacher.

Do this method works for an 08 Tahoe

I can't really find these cir diagrams to print out, any directions where to find them will be appreciated. Thanks.

Replace the dryer or vacuum for 2 hrs.

Just recently had one that held vacuum perfectly. Held 125 psi perfectly. Leaked at 175 psi Never any dye anywhere. Heater hose makes a good stethoscope.

Have a bunch of "Wide Range" B1S1 O2 Sensor parameters (impedance, heater, ...) but NO VOLTAGE parameter. Where is it?

Sir, among all the 'professional mechanics' out there, only you provided a workable solution. I found my AC leak in seconds after applying the shop hose. Bravo!

And 11:20 is why we have a drive cycle as the final step in diagnosis

Under the switched power there is a symbol C106, what does it represent in a circuit?

Excellent tutorial. Thank you so very much~! I'm a 70 year old woman and my 40 year old daughter and I are determined to fix this problem. LOL. However, if I were near you, I'd bring it to you for a fixin~!!

You didn't show how to remove the trim panel

Pressurising the system with air will definetely destroy the dryer with moist. Even after finding the leak and replacing your dryer, you will have to first vaccum the system completely, before proceding with anything else..

Because fuel regulation is at maximum and there is not enough pressure or it is in limp mode and does not allow regulation due to failure of some other component, good video and good exam case, I admire you a lot for your knowledge, whenever I have a difficult case you I visualize and think what would you do??? thanks for being

From this video I got the idea to lubricate the mechanical door locking mechanism, since my problem was intermittent. The lock did not spring back far enough to activate the electronic switch on my 2005 Pontiac Montana. WD40 fixed it!

This is the best video I’ve seen on the vac system and how to properly diagnose it from under the hood to the cab ., what a money saver, experience pays , thank you so much for sharing this, well done sir 😊🙏👍💯

I removed the gray block u see on the side of it at the beginning....problem solved....the new replacements are bigger junk than the factory ones
