I got a 2001 f150 leaking freon on the back of the compressor, can't afford to fix this summer. When I add freon should I get the freon with oil in to get oil in the system or just add regular can of freon, it took about 6 weeks before I need to add any.
View 7 RepliesI think the top AC line that runs from the back of the compressor is leaking on my '01. It looks straightforward to replace, but I don't have any way to evacuate or recover the R134a refrigerant. Is this something that an AC place has to fix, or is there a way to do this on my own?
View 1 RepliesOk, '99 F450 has had a/c problem for couple years and finally getting around to fixing it(co. truck and enough people complained).
When dead cold, compressor will cycle quickly, like low on freon. Low side goes from 40 to 20 and back again as it cycles. Put a set of good gauges on it today and I can't get it to turn on at all. Even jumped both hi and lo switches.
Originally I was thinking it was the clutch, but when cold I was able to jump switches and make it run continuously. I didn't have gauges then and didn't want to burn it up so now I have gauges and it won't come on at all(when warm). Will have to wait a couple days til I can try it again when cold(like in the morning before it gets used).
OK, until I figure out what to do with the other truck I overheated, I've got another ambulance that needs some work, and I got to have a truck running.
This is the same config - 2006 E450 6.0 dually ambulance with 122K. Starts and runs; I drove it all the way to Houston from Minnesota when I bought it and made several shorter trips since with no problems except the AC compressor leaks freon. Then, I found oil in the degas bottle. A tech said it needs an oil cooler and he says there's some leakage at the rear main seal that's "common with this engine."
Can't recall reading a lot of rear main seal issues here. Is that right? Is oil cooler the obvious diagnosis for oil in the coolant?
Of course my freon all leaked out of the AC compressor and it is squealing pretty bad. I did not want the serpentine belt to break due to a seized compressor so I looked for a bypass pulley kit. Naturally they make one for both gas engines, but not for the diesel. So out comes the string and sharpie, and trips to 2 different auto parts place to get the correct length belt after trying several that were too short. It's 103 inches (8 groove) for future reference to bypass the ac compressor and upper extra pulley. 7.3 diesel.....
View 7 RepliesSeems like my 2001 f350 7.3 has an ac freon leak on pass side near compressor. AC is blowing coolish air but not cold like is should be. There is green like oil around main line leading out of ac compressor. I have attached several pics to illustrate situation.
View 7 RepliesSo I bought a 2004 Jetta with the 2.0 engine yesterday. I got the car pretty cheap and was told that the issue with the A/C was because it was low on freon. I've never owned a Volkswagen before, but I assume A/C units are all similar. So I go to put in some freon into the low end of unit. I get about half of a 12 oz can or so in and I hear a loud Psst or shooting of the propellant. I look down and it looks like the the side of the compressor shot the oil filter with the coolant. I'm not sure if I sprung a leak of if it was just a valve that releases when there is too much pressure. I've only driven it for about 10-20 mins since and I can still occasionally hear the Psst sound. It is 96 degrees in my area if that makes a difference or not?
Some other information, I noticed that the compressor kicks on, but only for like a second or two and then it shuts off for about 15 seconds or so and then repeats itself. What could be wrong?
I have a 97 expedition that i am having trouble with. It has front and back airconditioner. The compressor is short cycling real fast. Warm air in the front and cool air in the back. I put a can of freon in but still not cooling. The gauges are between 30 psi and 50 on the low side. The high side is between 100 and 150 psi. The ambient temp was 80 degrees.....
View 1 RepliesSo today, I planned on switching the belt, idler pulley and tensioner since at least two of them are making noises. After taking all of the stuff off, belt, idler pulley and tensioner... and since I always compare parts I buy to parts that were in, making sure they are identical and I didn't order the wrong one. So first up I checked my tensioner and the position of them or angles are different, completely different.
So Google it to view a few diagrams and bang! it hits me... the one I took out from my F150 is for a non-AC... so back into the truck and I'm looking. Didn't have to go far when I realized that my AC compressor is missing!!!!
I keep looking around and I see that yes, I did have AC in it before I got it; because the guts are there but sliced! Great, so the job went from easy and easy I mean buy compressor and install; but now since the guts were cut, the PO sliced the thing out simply put.
1.) What are the bolt sizes that hold the compressor in place?
2.) Is there a wire connector on the compressor? or no?
My AC compressor failed so I replaced it.
I put in 1 can of R134, and I don't see the compressor cycling.
How do I remove the connector to the accumulator so I can jump it and force the AC to run.
I have a 01 f150 4.2L and a while ago the ac compressor clutch broke. I didn't catch it in time and the stress it caused on the belt broke the power steering pump pulley. So I replaced the steering pump and pulley and the compressor the accumulator/dryer and the office tube put the 134a back in and everything worked fine. three months later ac stopped working. I figured the condenser was bad so i replaced it. Charged it up still no cold ac. so i thought maybe the manifold that goes on the compressor was clogged so i replaced it. While I did that i said to myself well i should tear out the dash and replace the evap as well. so just about everything has been replaced on the ac system.
Aside from the cycle switch and the high side switch witch from my test both seem to be working. now here is the thing. the tube witch holds the office gets ice cold then goes to the evap but the suction line coming from the evap doesn't get cold and the ac blows warm air. this very problem is what convinced me that the evap was clogged and needed to be changed witch is why i undertook the task of tearing the dash out. in all it took 14 hours to do the whole job. now for the pressures that i get from the ac manifold low side goes 40 down to 20 ..... this is normal. high side is a little high. I charge it to 125 still no cold air. so i dump a little more 134 in. at 90 degrees high side pressure should be around 200ish i get it there still no cold air. I have just about replaced everything i can think of.
My air conditioning compressor is rattling and grinding. I am trying to determine if I need a whole new unit or just a clutch assy. I can say this, when running it's rattling, but when the clutch engages, it clears up.
Would I be right in assessing it's the clutch? 1998 250 5.4 .....
4.6L engine.......Well my A/C isn't working I just found out. The compressor is not kicking on. I checked the charge with my gauges and it is good so I don't think the low limit switch tripped, but I don't have a manual or anything and was wondering which number relay and fuse goes to the A/C compressor.
I also need to know which fuse goes to the power mirrors as well. I downloaded a manual from the ford fleet site, but honestly I haven't gotten around to looking at it. Not home.
I have a 2001 ford f150 with a 4.6 liter v8, my ac compressor is completely seized up, I can't afford to replace the ac right now. So I would like to just get a shorter serpentine belt to bypass the ac for now, need to get a measurement on the shorter belt for my engine? and the proper way to re route the belt without the ac?
View 7 RepliesSunday afternoon I noticed my 97 F-150 4.2 5-Speed manual had a higher idle. When the AC compressor kicks in, the motor revs up higher than normal for about 4 secs then comes down a little. If you barely press the accelerator, I mean just gently touch it, the motor revs up for 4 secs. Dont have a tach, but just idling in neutral, is about 150 rpms more, and when AC compressor kicks in, rpms jump about 300 rpms i assume. Maybe vacuum, IAC??? Plugs, wires, and normal tune up done about 2400 miles ago.
View 2 Repliessoo a friends 03 f-150 w/ the 4.6 has noticed the a/c compressor clutch engaging while heater is on. clutch engages for about 3 seconds or so and kicks back out consistently but only w/ the heater on. a/c dose function property when using a/c functions... Is this normal or does something need serviced???
View 3 RepliesI drive a '99 F150 4x4 5.4 EFI 196,000 miles. Recently I started noticing a growling noise that followed engine speed. I immediately thought alternator going out. So I pulled the belt off and it spins free and doesn't feel rough at all.
So I started it up and realized the noise got a lot louder when the ac clutch cycled. Now I'm thinking ac compressor. A short trip to my mechanic who didn't even really look at it very long and he said the compressor is about ready to seize up. I thought I might just put on an ac bypass pulley to get by for a while. Not really a sound decision in the middle of July, I'm thinking, but I'm poor and it beats having the compressor lock up, right?
Today, when I get off work and pop the hood with the ac off and the clutch not engaged the noise is worse than ever. I put a stethoscope (long screwdriver, I told you I was poor) on the alternator and it is making all of the noise. Turned the ac on again and it was really making noise now. So I applied the stetho-driver to the ac compressor and it is quiet as can be.
I am cautiously optimistic that the alternator is the sole culprit and that it only gets louder when the ac cycles because of the extra drag on the belt.
Does that seem like a logical explanation? Should I just try the alternator? I really don't want to destroy a perfectly functioning ac system only to find out that it was OK to begin with and I don't want to buy a $150 alternator for no reason either.
My 2003 F150's compressor cycles even when the a/c or defroster is not turned on. It has the climate control type of temperature system. This doesn't seem normal.
View 2 RepliesI have a 97 f150 5.4 4x4 a/c compressor and clutch. It won't let my motor turn over because the ac compressor is locked up bc the bearings are shot is there any way to by fix this until i get a new compressor and clutch....
View 6 RepliesI have a F150, 97, 4.6L. I changed my Suspension belt, and now my A/C compressor is not engaging. This has happened before, and when I took it to the shop, they called me and said the A/C works just fine. They did not tell me why the A/C stopped engaging or what they did. I tried to locate a relay fuse, but I can't find it.
View 5 Replies1997 F150... What part of the control system tells the compressor to turn on and off? After not having air conditioning for a year or more I replaced the broken blend door.
When the a/c is turned on and the temp control switch is turned to cold, I get cold air. When I turn the temp control switch to warm, the air coming out of the vents is very warm. However when I do this I noticed that the compressor is still engaged. I think that at this point the compressor should disengage.
