Vacuum pump motor concerns on the Ford 6.0 f250-f350 Powerstrokes Superduty

I get calls asking me how to diagnose the vacuum pump on these trucks so I hope this does not over simplify it. Similar on the 6.4 which I will show in another video

[@laweagle83]

Ron still helping long after his passing. Found that little vacuum line off, just like he said it would be. RIP brother.

[@zman8613]

Just helped me, sad to hear of this news. RIP Ron, thanks for the help

[@sw-iz1ux]

Thank you for keeping Ron's channel up. I would be proud to call Ron my friend. He is still "The Man".

[@jumpinggulley]

Such a great teacher, true professional. So glad he spent the time to make these videos.

[@user-je5fg8mh4h]

So informative, he is sorely missed!!!

[@jonpearson2175]

Second time in a week Ron was able to help me with an issue with my 06' F250. Both times I panicked thinking it was something major and thanks to these videos I was able to troubleshoot and repair with no expense. So sorry to hear of his passing, RIP sir.

[@closnapoli7397]

Ron, first rest in peace, I just found this disconnected os you said. You were the type of person that made things better in this world. Thank you and god bless..!!

[@stanralph9738]

Thank you Ron. RIP ;( . God bless those you left behind.....

[@scottfrancis3072]

I miss ron, his videos helped keep my 6 liter power stroke running. He was is an awsome mechanic. He is stil teaching and helping us diesel guys today. I have learned so so much from Ron. Rip

[@dxpvxo711]

I spent forever trying to figure out what these parts are. Count on ron to the rescue. Rip ron

[@adamcuttler9665]

Thank you RON! You helped me many of times and saved me thousands in repairs by doing it my self. RIP bro.

[@rangerguy196]

RIP?

[@lindabond1569]

So sorry he is gone. What an excellent teacher and sure knew his stuff well.

[@atcaleb]

this video fixed me today. 03 f250 6.0 4x4 had heat only thru defrost. i followed the steps and found my egr vac reg was bad. i pulled no hair in the process. thanks. a million.

[@1stiholland]

thank you for the help just fixed mine, I live in Florida an today it was 95 and was sweating bullets. thanks again awesome videos

[@markymarqca]

Thank you Ron - solved the vacuum pump not shutting off in about 30 seconds thanks to this video; it was the line off to the heater control valve. Thank you!

[@TJSTEDMAN]

Just bought an 04 6.0 dually that runs great but I heard a little noise when I start it and a hissing when I shut it off turns out it was the vacuum pump I thought I had 2 separate issues. This man has helped me so much in the last two weeks learning all kinds of things to look for diagnose for upgrade to. Thank you very much.

[@danb372]

Still helping us out, brother! It's been a great run with my 6.0, she's been my daily for 15 years. I just took delivery of my 2024 F250 in the 7.3. Found a good home for the 6.0, some 6.0/7.3 guys up in PA. But wouldn't ya know it, checking the 4WD today the vent air blew out the defrost which is always the tell-tale sign of a vacuum leak, so I had to check in with Ron one last time. Thanks for everything, Ron. You are missed!

[@echotoday]

Diesel Tech Ron has saved me thousands of dollars. An excellent resource for a DIY individual.

[@richardcabitto5108]

Started dealing recently with several 6.0 and 7.3 Powerstrokes with different issues . Found Ronald's info to be spot on! RIP

[@daviddennison3339]

And also me today! A great teacher never stops teaching, Thanks so much.

[@langstonmcgee]

I had this problem. I was extra concerned because I had manual Warn hubs on my rig but the hose lines still go to my hubs. I inadvertently fixed the problem by removing the gray vacuum line (5:36) and putting it back on. It must have not been seated correctly. Hey! I'll take a win whenever I can. Thanks Ron! You are the best!

[@brianlong828]

Well done. My 2006 F350 Vacuum pump started running the other day and ran almost incessantly every time I turned the key on. I prowled all over the diesel tech sites and everyone was pointing me towards bad solenoids and leaks in the HVAC/FWD lines. I watched your video and, as you described, the grey line to the little black heater control valve at the back of the motor was unplugged and hanging all the way down the back of the firewall. Popped it on and presto, good as new. Thanks for your great and explanatory videos.

[@theschmerbs435]

Hay man I️ got a 06 engine check light just came on wile I️ was toeing my boat it runs fine system check was fine but light has not reset and ideas..thx for your time

[@jacobpeek9699]

I find you to be an excellent teacher thank you so much for taking the time to make these instructional video, if you ever decide to make a complete 6.0 troubleshooting dvd I will be the first to purchase! God Bless and thank you again!

[@MrParanoidmedic]

Thanks Brother! I fixed my truck. It was the 4wd Solenoid.

[@YahikoHaldane]

Ron, Thanks for the tip on the heaver valve. Mine was in the wrong place. The last one to work on it was the Dealership. Head gaskets. Funny that got missed.

[@yeahno1016]

You rock bud. Great vids for owners trying to learn DIY to save huge hourlys.

[@robelpesao]

Awesome!! Thank you so much. Followed your steps with patience and BINGO!

[@kturne06]

Thanks for the help. You diagnosed my problem at 02:10. That hose was off it's port. The vacuum pump would cycle on and off, on and off, but with that line disconnected no air except to the windshield vents. I think it was knocked loose a couple of weeks ago when it was in the shop for a turbo problem repair.

[@rangerguy196]

Air was only blowing through the defrost vents in my 2005 F350 Super Duty. Several people were telling me the climate control in my truck was shot. I stumbled across your video and sure enough, the vacuum pump in my truck wasn't working. One trip to Napa and an hour later and everything was working correctly again. You saved me from wasting $400 on a new climate control unit. Thanks Ron!

[@tuckerhodges5896]

We miss you Ron. Still helping me to this day!

[@Coachbob41]

Ron's Lives! Fist it was the FICM...fixed. Then dummy plugs..fixed. Now vacuum pump....Ron Lives !! Thanks again Bud ! RIP

[@brendasmith5937]

Ron is gone but not forgotten. Still schooling me and my Ford! RIP Ron!

[@dut822]

Thank you for this post. Was able to narrow it down to my 4x4 actuator.

[@salvadorortiz-wt5ne]

Thank you for sharing. My vacuum pump would not stop running. Mine turned out to be the hub locking solenoid. Seems to be working properly now.

[@jjmcq2327]

Ron thanks for the video, My pump has been doing this for too long. I went out did your test found an unplugged The heater has been defaulting to defrost with the AC on. Hopefully the fix will be permanent.

[@912cal28son]

You saved me. Thank you. The dealership did this to my truck.

[@noacktexas]

You fixed my issue!! My grey line was just sitting there not connected to anything! Thank you sir!!

[@joshuarockwood]

Where does the grey line that goes to the valve come from? Mine is missing

Sorry to hear that....

[@kevinkovalesky9383]

Ron I watched your video and determined my vacuum pump went out completely. I have replaced the vacuum pump and now all of the heating and cooling vents in the truck are working properly. In addition, the grey wire was not attached so thanks for the heads up. Now, the SOF 4x4 still does not work for either 4 high or 4 low after fixing the vacuum pump issue. If I manually lock the hubs then everything works fine. Is it possible the 4wd solenoid has gone bad? Is there a way to test if the solenoid next to the vacuum reservoir and vacuum pump has gone bad?

[@chadsmith8779]

Great video!

[@jimmymontes7426]

God bless RON. My A/C was not blowing through dash. Tested my pump and what do you know, it's not working. Simple fix

[@eddiebreedlove1293]

[@seanreynolds1081]

Ron..regarding my ac & heater, I'm not getting any air through my interior vents? Is that a possible vacuum issue?

[@rvproductions3632]

Muchas Grasias Amigo Dios te tenga en la gloria

[@dirtyminerapparel]

Wish you were still around brother. Hope you found peace.

[@jongreene6888]

Not a bad video, of course besides all the hoses you stated, I'd also check inside at the bleed door behind the glovebox. Especialy if after all the checks you stated, if the bleed door is losing air then the pump will keep running.

[@AlexXHitchcock]

I had a vacuum leak not mentioned in this video. I had a battery fail and leak acid. It got on the resivoir and ate away at the side causing it to leak. The first symptoms where the AC vents taking time to shift from defrost. This was on an 03 F250 7.3L

[@echosixdefensesolutions912]

William, your reply was how I just found my issue. battery acid put a hole right in the side of the box. guessing an epoxy fix?!

[@AlexXHitchcock]

@@echosixdefensesolutions912 that would have been an option. However, my Father is a pack rat for vehicle parts and actually had a replacement for it in his shop. Glad I could help!

[@echosixdefensesolutions912]

@@AlexXHitchcock i mixed up some double bubble and in 5 minutes I had wind again!!!

[@denniswakula1446]

what if my vacuum pump continues to run when i hold my finger over the hoses to the vacuum reserve tank? i have factory manual locking hubs so i do not have the pulse vacuum actuator.

[@Mikeynuts21]

Thanks Ron

[@scottfree3719]

The 6.4 vacuum reservoir has 2 ports out a small one goes the tree from the vacuum pump and the way goes 4x4 solenoid. the other port i don't have a hose, but Ford schem for the 6.4 shows a hose but I can't find any information on where this hose is suppose to go or what it does. If Ford makes it it would be on the King Ranch, .

[@scottisaaks]

After all this I think my res tank is bad. Is it ok to unplug the vacuum pump so it doesn’t try to feed the system and burn the pump out tto drive it for awhile before getting the res replaced ?

[@Jay-ff8mw]

Hi Ron, my pump will not shut off even when I plug the lines coming off the reservoir. The reservoir holds air pressure even over night so I know there are no leaks. But it will shut off if I plug the intake nipple on the pump. Will a weak pump cause this? Seems like it takes a while to get good pressure.

[@rustynail3159]

this morning when I got into my 2004 F250 6.0 diesel I heard that same humming noise from up front and I just ignored it and started the truck and took off and in about 4 miles down the road I lost throttle response and my truck died, I then waited for a few minutes and tried starting the truck and it fired right back up but then I only got a couple miles and it died again. Could this have something to do with that vacuum pump?. Thanks

[@erickmejia5593]

hello have a question about the vacuum, if the vacuum failure, the break and the power steering wheel well lock. experience I was driving my f350 2003 6.0 about 80km and that happen the break and the wheel lock 🔐. that is related to the vacuum. thanks

[@kasparsfreimanis4196]

Thanks... nice video..

[@shbroneswygert6243]

Do the 05 F350 super duty have a reservoir on them

hey Ron how are things...well i hope ?got a question my temp. on my ac fluctuates from cool to warm or hot while on.so i turn the function control to off wait a few min. then its cool again,,,but keeps repeating the symptom over and over.can you help plz going on a vacation shortly?Thank you Ron

[@Dan.mapp.]

+DieselTechRon i have a problem with my 4x4, both hubs are new, when i turn the hub to "LOCK" and have the ESOF switch on 4x4 it drives both wheels fine. However when i turn the ESOF to 4x4 with the hubs in "AUTO", the transfer case engages and both axles spin but no drive to the wheels. would this be the switch you spoke about? if so how do i diagnose this

[@102375jhr]

I have a 2004 f-250 6.0 and the horn is popping fuses. Any suggestions on where to look to fix it? Thanks.

[@happy123854]

can you tell me where the transfer case module is located on a 1999 f350

[@aoleson]

I have a question Ron.. Are the 7.3l hubs known for going out in the vacuum side of them??? I have one and the hubs seen to have a mind of their own lol.. They will work when i don't need then like when I go to back up my big trailer in reverse up my steep driveway.. I put it in low to keep the stress off the trans but I don't like the Hubs to lock do I don't get all the binding on the pavement... But when I really need them like when I'm in the sand they never seem to work so I have to get out and lock them.. Do the early years of the super dutys have hub problems?? Cause I have yet to see the newer design on the late 6.0s and 6.4s not work...

[@DieselTechRon]

They can. In the video I was talking about vacuum bypassing the valve and causing a leak. Your talking about the effect. If it bypasses then yes it will apply the hubs.

[@juanalvarado7328]

hi i have ford f 350 6.0 2004 i change turbo but keep going engine ligth turbo under booster

i am just trying to figure out what the figi is a vacuum switch and vacuum gauges is doing under my dashboard near the gas pedal. my net is experiencing some turbulance so i can only play about 8 seconds of video for every 10 minutes. I have a 2000 ford f250 gas 5.4L. with some weird vacuum switch unit under the steering wheel.

[@quadragin]

Our pump seems to be working fine no leaks, pump will tun off after vacuum build up occurs, our issue is this, we have ONLY air flow to the floor, Nothing to Defrost or dash vents. All we can find is Air pressure at Defrost only which means no vacuum to controls..

[@392nightrunner]

2:15. Thank you.

[@davidpatrick1813]

I more or less did all this .. but the vacuum actuator, ... idtentifx I think said if it doesn't hold a vacuum to replace it. So I put my mighty-vac to one side of the actuator and put my finger over the other and it does NOT hold a vacuum or move the needle. I can pull plug the red hose at the actuator unplugged and it pump stops. I am thinking and actuator is kaputs.

[@keionhartzog1069]

[@michaelcorrieri6117]

Are you still watching this? where does the OTHER end of the heater control valve vacuum line go? my vaccuum pump runs constantly. I isolated that it's not the 4wd or other front items by disconnecting the line as shown at 3:31. But the hose you connect at 2:21 comes from somewhere that is disconnected.

[@gogoj1]

Thanks! very Informative. My '05 Super Duty 6.0 has problems starting up in MAX AC - it blows through defrost. Pulling the dash and listening for hissing vacuum leaks at the control switch - in MAX AC and 'O' setting can hear a little leak where the tubes plug into the control panel and the vacuum pump never shuts off. All other settings no hissing and pump turns off. Any thoughts?

[@Mark_Tschetter]

How much vacuum should this pump make?

Hey Ron- i know you are talking about a vacuum pump. But could you make a video about The power steering box? IM having a horrible wonder issue but im not sure what is the problem. The Pitman arm bolt seems looose. But only moves Up and down when i hardly turn the wheel. But no side- to side movement. any tips?

[@jeremylb86]

I'm no Ron but I have owned 3 of these trucks and all were lifted this is what i'm going to use to solve this problem bulletproofsteering.com assuming your running over sized tires as i am the factory joints and tie rods cant handle it like these over knuckle joints can and the whole system is cheaper than replacing your ford factory steering parts. hope this helps

[@DieselTechRon]

We got a lot with the pitman arm being loose if not worn. some of them with lifts are hard to check the torque but you should esp if it moves. We have seen the shaft break so be careful.

[@Zero12495]

DieselTechRon The output shaft is solid- Arm movement is up and down kinda like some teeth are gone on the arm. :/ But i will check out bulletpproofsteering thanks jeremy! and thanks ron. i just hope i can drive my rig still up and down play being about 2 inch play is bad?

Ron, I have a 2001 f250 Superduty 7.3. The AC and Heater fan blows through the dash vents perfectly until I place the vehichle in 4 wheel high. Once I take it out of 4x4 high, the fan blows out of the dash again. Ive done the diagnostics tests, replaced the pump and 4x4 actuator as well as the rubber vacuum lines on the hubs. Any thoughts? I'm stumped...

That isn't a bad price if the truck is in good shape, but there are so many variables and it always depends on the condition and options.

its a lariat with everything and the body and frame from the pictures look amazing i see no rust at all ill have to check it out sometime this week

[@DieselTechRon]

Ryan Collins try to start it cold, make sure it doesn't miss. I would take a scan gauge with me. Monitor ficm volts, turbo VGT, oil temp, coolant temp, voltage, make sure the cooling system pressure doesn't get too high and vent out the cap, and you should be good!

now would that all read on a code scanner? i was planning to take a ride there and you know say i saw the truck from the road and id ask if its for sale the i know they wont have it running before i get there. but im also going to bring my dads friend who is a mechanic to help out
