- This is NOT 100%... But as close as I can get to it since " Variations " due to different Models / Year and YES, there are differences. If any corrections needed to be done... Please leave it in the comment so I can update the description to help People. I myself had a hard time finding the right " Routing " and this is the best I can come up with.
Where did I get my " Source "? From a 1996 Chevy Blazer and a 2001 Chevy S10 Crew Cab.

@Scott Lawder
- You are welcome!
Thank you brother! This is extremely helpful.
You're welcome!
That has to be the best explanation I ever seen on the 4.3 vaccum system. you should get an award for the most informative car dude🖒
Thankx! Glad it was able to help you!
What aren't there more likes? This is an incredibly useful vid
:)
Thank you sir. I have looked for this for about 3 years.
You are welcome!
Funny how you can't find a good diagram on the 4.3 vacuum system. I had bought one of the "fix-it" books, they had nothing! Thanx for the sketches!
Glad I could help!
Thank you for this video. I had one little vacuum hose unhooked and now I have Ice cold AC.
Cool!
@@JodBronson literally
@@WatsonHerbush - You are welcome!
You did it. The only thing still out there in layman's term is this video thank you again
If you can do better.... MAKE THE VIDEO YOURSELF !!!
@@JodBronson I said thank you. I couldn't understand anything else out there. It helped out a lot. I was getting frustrated and then I seen your video and i got it. 2004 blazer 4x4. I appreciate you.
Man my blazers vac lines are fubar. I gotta fix it. That’s probably why the 4x4 isn’t working lol. Thanks dude
You are welcome !!!
Great video. Helped sort out routing problem
Great !!!
Thank you very helpful
You are welcome!
This was super helpful- clarification question (previous vehicle owner cut one of the lines short) I have a vacuum line running from the Evap-Canister and then it goes down on the passenger side of the car between the distributor and firewall. It seems to be heading down towards the axels- is that one of the lines that go to the three prong transfer case?
YES, from the one that splits and go down to the Axle is the Splits - 3 Prong - Transfer Case breather. Some actually go all the way back to the Charcoal Canister too (Gas Vent). See diagram in the video.
Good south. You know my blazer by dipstick oil motor I saw it fluid transmission tube breathing likes fluids up leak on the cap. I tried figure out as struggling
Great job
Plz correct me there are transmission case and tranfer case both are saprate from each other and both have there own vacume supply from switch when the swith ball moves up the transfer case vapour suck trough into the engine..??
This is why I subbed
@Francisco Verdugo
- If you need help with something, just ask! This was a request from a person that waited like 2 Weeks, LOL. But finally I was able to do it for him since he can't find it anywhere on the Web. If I know something, I can always make a Video and maybe People also can benefit from it as well. Surprisingly...., There is NO Video on RUclips going through these details. This is as much as I understand it!
@@JodBronson thanks lad happy new years
@@franciscoverdugo4021 - You are welcome and anytime! Also, YES... Happy New Year! ✨✨✨✨✨✨✨✨
@Little Skummer Boy. - Thankx!
Great info, very helpful for those who needs it, l wish there was a video at the time l had my blazer, now it's sold.
Is this vacume system in your video is like vacume pump in nowa days car wich drives by cam shaft ??
Umm . I have an 2000 s10 RWD LS. I have a three way splitter next to the vaccum canister, one goes to the throttle body, the other goes into a harness into the dash.. i think ill need to buy a aftermarket vaccum ball because mine is broke. What im confused about is the line yhat goes into a wiring harness lume, and into the dash.. just seems kinda wierd. This on a 2wd version.. suffering check engine lights rough idle, stalling.
The one that goes into the Dash = Heat Actuators.
Thanks for the diagrams and stuff, but my 2000 s10 4.3L has no split line from the 4x4 actuator to a fan under the battery. It's just a single line straight in to the actuator from the 3 point solenoid behind the transfer case. I have a line broken off coming from above my transmission and can't see where it broke off from on the motor side, unfortunately. Is that coming from the canister, maybe?
Not sure.... Just trace it step by step and follow the Lines. As for splits... You can buy the "Splitter" and do it yourself and to your liking. Pause the Video and follow the Video so you can go Step By Step. So far, that is the best known routing I could come up with. This info was on 2 Cars / Truck and it's 1996 Blazer + 2001 S10 Pick Up. NOTE: If yours doesn't have the Split from the Fan / Battery... That means it's an Older Truck / Car and only apply from 2006 and under. At least you don't have to worry about that. NOTE 2: As for the broken line splits, pause the Video where you see a Diagram / Picture which tell you where things goes. SO WATCH THE VIDEO AGAIN AND AGAIN to see if you've missed something.
thanks 4 video...i have 96 s10 4wd 4,3..i have vacuum leaks on this truck.........Where is the starter relay on this engine ?
Starter Relay is under the hood, in the passenger side. Open the hood, you should see 3 of them there. Once of them is the Starter Relay. I am not sure which is which, but the one with the thick YELLOW Wire.
Go to the video link here... You will see it in the video !!! ruclips.net/video/a1tN29zEgH8/видео.html
there are 4 identical BOSCH relays..mounted to firewall inside engine bay...passenger side
i just back from truck S10 1996 4.3 4WD X vin#...NO YELLOW wire going to any of the 4 relays...I also called 2 GM dealers in my area...THEY were useless helping me to find it.
@@williamcox2996 - Amazing what you can do in 2 seconds! Here: www.autozone.com/znetrgs/repair_guide_content/en_us/images/0900c152/80/07/05/df/large/0900c152800705df.gif
The transmission vapour is also going in engine.???
YES !!!
Starting 1996... The EPA (Environmental Protection Agency) forces ALL Car Manufactures to do it. Anything that has a "Vapor" can not release to the enviroment, it has to go back for a "Re-Burn". So vapor from Oil, Transmissions, Wasted Gas (EGR), Etc... Needs to go back to the Throttle Body for a 2nd re-burn.
@@JodBronson so thats y air reservoir and all of that stuf needed..?
@@aliqadri4672 - The Vaccum for Brake and Actuators, Heater, 4X4 Switches, Other Switches etc...
@@aliqadri4672 - BTW... Air Reservoir = Air Reserve. See how English works?
I got a question I got an awd version and the pcv line its cut out what do I need to do its a 99 bravada
PVC goes to the Air Filter.
Pause @ 5:03
Does your vacume system is conected to brake booster too ???
No, Brake Booster is separate. They design it that way for a reason !!!
@@JodBronsonyou help me alot bro thanks. whats the reason why it is not connected to brake booster and give me the list plz wich wich parts does your vacume system is connected to ???
@@aliqadri4672 - The EPA wants EVERYTHING that produces "vapor" connected to the Vaccum System.
@@JodBronson but some one says in this comment one hose from vacume is conected to brake booster for ease of braking
@@aliqadri4672 - Learn to read + comphension.
Geta chinese tech 2, Will work on it
You need to lend me yours, LOL
Won’t fuel line get sucked closed as air line is harder
Check into Fuel Lines verse Air Lines and do a comparison for yourself. Air Lines when hot or old, can collapse really easily. Fuel Line can withstand high temperatures and is very rigid. Except in Low Application like a Weed Wacker or Small Engines, like 2-4 Stroke.
#1: Due to the dangers of fire and or blowing up, Fuel Lines are very rigid because they do not want leakages or fire or blowing up.
#2: Air Lines for your little Fish Aquariums or Air Compressor Tanks, both are different too.
@@JodBronson super. I got some bad corroded hoses at that white 1 way check valve so I guess that’s my issue!
@@Loctain- Check or Inspect all of them for Cracks or Old. In Car or Trucks or this 4.3L Engine, since it's big in HP. Those hard White / Clear Hose are rigid, because they are in a "low/freezing" temperature location, but still not regular air hoses. But if you look at the area that is hot or potentially hot, they use Black Air Hose. Those Black Air Hoses actually get soft when hot and when Old or Cracked, they actually collapse very easily.
NOTE: Black Air Hose is the #1 problematic in Cars / Trucks due to manufacture costs. Those are cheap - cheap hoses that they put in there.
What does maf sensor do in all that vacume system ???
4:20 why this device have ball at bottom ..??
Extra + Reserved Air
@@JodBronson and where does it fix on tramsmision case or transfer case??
@@aliqadri4672 - In the video + diagram
@@JodBronson so when the transfer case pressure is geting high so the ball below on switch is getting up and releasing oil vapours to reburn ??
@@aliqadri4672 - YES.
Is 98 same? I cant find reservoir
I stated 2 known locations in the video !!!
Inside the driver side fender on my 98 Blazer.
Where are you from 🤷🏽♂️ your accent is messing my brain up.
Never mind about my accent... Watch and learn so you can apply to your Car / Truck !!!
