F-150 won’t start, A/C compressor replacement.

- I went to the gas station to buy a rockstar and when I came out my 2001 F-150 wouldn’t start. I thought maybe the engine had locked up because the starter was engaging but it wouldn’t turn over.
I paid a local towing company $80 to tow it to my house so I could diagnose and repair it. It turned out to be the A/C pump. I got on RUclips for some research and couldn’t find any videos on how to reach the top manifold bolt and wire. So I made my own video with that as the intro.
I’m not going to lie that top compressor bolt almost sent this pickup to the car crusher as the price of scrap is up a bit currently and it tested every bit of patience I have. I’m not a certified mechanic obviously. Take any advise at your own risk. This pickup was my dads. He bought it with 9k miles on it in 2003. He sold it and his camper to me at a discounted price with the promise that it will be my son Calvin’s first vehicle. I don’t know why Ford made the A/C pulley a mission capable part of the 5.4L Triton. A guy used to be able to just kick the belt off and keep driving but I guess that would defeat their planned obsolescence.
I always leave some weight on the jack and some weight on the jack stand when working under a vehicle with the tire removed. I also put the removed tire under the lowest part of the frame as close to where I’m working as possible so it won’t completely crush me if it falls. I’ll put 100% of the weight on the jack stand and then give the jack a couple pumps so they’re spitting the load. I don’t know where I learned it but it’s just my standard for working under a vehicle. It also helps so all of the weight isn’t on 1 spot on the ground. You should always give a jacked up vehicle a good body weight wiggle. You might bump the jack with an elbow or have to pry on something and that’s a similar force so better to test it first when you’re not under it.
To get the pump somewhat held in place I put the manifold bolt in a little bit and hung it on the manifold. Then I tightened it down and was able to use the hard lines to move the pump around as needed without having my hand down on the actual pump. I used a tiny bit of oil to lubricate the top housing bolt so I could get it started easier. I didn’t use locktite. Think this truck will have a new engine before the compressor vibrates the bolts lose.
I dont usually comment, or even like videos. I get what I need and I go. This video however, was the best video I’ve found on this so I truly thank you so much!
Thank you sir or ma’am I appreciate your comment and kind words.
Mike I would love to visit your state one day they say it's beautiful. My wife is sick now and can't travel, but we hope to get out West sooner or later .❤ redbaron Chattanooga TN
It’s beautiful and peaceful most of the time. I’d recommend June. It doesn’t usually snow or freeze that late in the year. It’s usually in the 70-80’s and the mosquitos haven’t gotten started yet. Medora, Theodore Roosevelt National park and the badlands in general would be worth the trip. There are a lot of hidden gems out here.
Thanks. Could not find that 4th bolt on top.
I did a by pass on my 2002 f150 super cab fx4 5.4 v8. I replaced the idler pulley with a 6 rib idler pulley and a shorter belt. Fired right up and no issues no squealing. Go to O'Reilly and ask for Murray pulley part number 2330012 and belt Gates Micro V k060798. Just make sure to route it right.
When I did this repair 2 years ago the reman A/C Pump online was like $20 more than the bypass pulley at our local Napa. I would assume I could’ve found bypass online for less. But I did end up charging the system and had A/C for 2 summers. The transmission on this truck has a shimmy when it goes into overdrive so I pulled the insurance and it’ll be sitting again for a little while.
Thanks but change music, silence is better.
Dude I’m terrible at making these videos. I never thought anyone would actually watch them haha. It’s just an expensive hobby that I’m not very good at and I’m ok with that.
When I first started making videos I didn’t know how to get unmodulated music. I would literally have to play the song on my Chromebook speaker while my phone recorded it in a voice over on the video editor. It sounds pretty bad but it was the only way I knew how at that time. I’m taking a brief hiatus from video making at the moment because we just had a baby on June 5th and I have more responsibilities around the house for the time being.
Your issue was probably a bad pulley bearing I bet that compressor was still working.
I disagree. You can see at the end I found where the leak was and it was wet from oil leaking out of it along with the refrigerant. My assumption is that it pumped the refrigerant and pump oil out of the system and was lacking proper lubrication for the internal pumping mechanisms and it ground itself to a halt internally. Additionally there was excessive clutch material in the vicinity of the pulley indicating that it had been working very hard to keep spinning. It’s possible that a bearing could cause that as well but with the evidence of the oil leaking out I would strongly argue that the pump itself burnt up. If it was the bearing it wouldn’t have been much cheaper to buy a bearing and replace just that. Additionally the average non-certified/diy/parts-swapper isn’t going to have the tools and experience to tear a pump down and replace the bearing. Ordering a reman pump is more efficient and manageable for the average Joe which is who this video is intended for. Also if a bearing had gotten that hot on a shaft that small I wouldn’t recommend reusing the shaft either. Most people don’t have a lathe to turn a new shaft and I have my doubts that anyone would sell one individually. I wouldn’t recommend a junk yard pump because you’d be lying in their mud pit with a hand full of tools trying to get the pump out.
@@MikesMischief I see the main crank seal failed probably.
@chriss4365 there wasn’t any oil on the pump itself. It all leaked where the soft line meets the hard line at the condenser under the passenger side front bumper. I’m not saying the bearing didn’t fail but I’m pretty sure there wasn’t any oil in that pump for about 9 months. It was my only reliable vehicle and I couldn’t afford to have it done and didn’t have time to do it myself. I was working 100 hrs/wk in the oil field and I only drove it about 50 miles/week. That front pulley had zero movement. Not even a wiggle. It felt like it was welded to the pump housing. There wasn’t any rattling or anything. It’s possible it was the bearing that welded itself together but whatever it was for me personally it was cheaper to just replace the whole pump.
@@MikesMischief Any idea why the lines that connect to the compressor would have a leak? Mine is leaking and I cant pull a vacuum no idea why, the lines are tight on the compressor. I will be taking it apart tomorrow again to investigate. Im guessing maybe somehow the seals even though are new are the issue so I will change them. I know it's the seals because I could hear it when I had the vacuum pump running amd is a small amount of oil around the lines where they connect.
@chriss4365 try to replace the O-rings on the end of the lines. They can dry out and crack. Also could’ve had a rock kick up and put a pinhole in the line.
10:47 totally true!
Thank you Lawrence.
Great job and good advice!
Thank you Emil!
I like the lost footage is of the refrigerant being " reclaimed" 😉 I see ya over there. Also I know this is late and all but it's well worth spending the extra money while you have the system discharged to replace the orifice tube that way your warranty on the compressor stays good. Also when the compressor takes a poo poo like yours did it sometimes spits junk into that tube that clogs them up and really gums up if not totally clogs the ac system. Great video btw, as im about to tackle the same exact job on my mothers 99 expedition... They don't give you much room when you're on your back on the ground do they? One more thing, I am damn surprised that your digital dash works for the odometer, those usually go bye bye
There was a leak in the line that the oil and refrigerant had leaked out of. The ac hadn’t worked for probably 5 years. I wasn’t planning on recharging it at all and almost put a dummy pulley in it. I only use this pickup in deep snow or to tow my boat or camper. My neighbor Corey saw the hood up and stopped over and offered to recharge it for free. I thought the engine was locked up. I have rebuilt the cooling system on a D9 Dozer and did it the book way and replaced the orifice and pulled a vacuum prior to unhooking the lines. Lying in my grass with the ticks and sticks I mostly just wanted my snowing and towing rig operational. I put a hose clamp right over the area where the oil had leaked out to see if by chance it would stop the leak. The ac has worked pretty good the last 2 summers of boat towing.
@@MikesMischief I was only joking about the refrigerant bud, I have to say this was the most informative video I have seen.... I am about to tackle this task myself and im trying to see if I need to replace the AC condenser as well...
@Medic 6934 I honestly never thought anyone would watch any of these videos haha. I’m happy to help if you have any problems you can dm me on instagram if you have any questions. I don’t think you’ll be able to do it without that floppy ended wrench. This pickup was my dads and he wants it to be my sons first vehicle. I initially thought that the engine was locked up so when it started after removing the belt I was relieved. The dummy pulls is only about $40 cheaper than this pump so I figured it was worth a shot. Dad refilled the refrigerant at the beginning of summers and only god know where the previous years refrigerant went.
@@MikesMischief its a great vehicle to be a first vehicle.. hell I want my mother's expedition because it's so easy to work on and is still running smooth and reliable... Those 4.6 motors are strong... Thanks for the offer and I will definitely hit you up if I have a problem.
Do you even need a/c where you live?
It would be nice in August. We get some hot ones in the summertime. It’s pretty silly of Ford to design it to need that pulley. Planned obsolescence I think but we overcame and git it done.
For the sheep lol
