What is cycling? I am guessing it is the compressor turning on then off? My compressor seems to always be engaged when my a/c is on. Is that bad?

Well I'm glad to be on this forum, you guys have a lot of knowledge :) I added refrigerant today, although the air seems to be slightly cooler, this didn't solve my problem either. I have noticed that as long as my rpm's are 2k and above the air feels cold, not as cold as I would like, but...

So how does this relief valve work? Is it supposed to release refrigerant if the system is over-charged?

I added some refrigerant to the system. It's 103 out side and I have a pressure reading right in-between 50-55psi. It still doesn't seem to be blowing that cold. I have sprayed cold water on the condenser and yes it did start blowing colder air then normal while at idle. The reason I added...

Does anyone know what the air pressure is supposed to be on the low a/c port when it's like 100 degrees out? I think I am going to try to recharge again.

The fan clutch looks spotless. I did the cold start test and the fan seems to be working ok. Would replacing the thermostat and coolant help? I have 175k miles now and I don't know if either of those have ever been replaced. I got this vehicle from my grandfather, who I know did basic...

Is it possible that my fan clutch has gone out? How would I test that?

I checked and I have a metal fan...I don't know what kind of fan clutch it has.

In my experience having only one cylinder misfire the cause has usually been the spark plug or the wire. Have you tried swapping the spark plug wire with a known good one? Is the number 6 spark plug tightening down properly? My brother-in-law has a ranger with the 4.0L in it and he stripped...

Any suggestions for an electric fan I could add on easily?

So if I were to add an electric fan this might help my situation? I did have my car on and ran it for a little while before I tried charging the A/C. I watched the gauge for about 10mins and it stayed the same.

This might sound like a stupid question, but just trying to get a little more information. How do you know it's missing on cylinder 6? Are you sure it's not missing on more then one cylinder?

Ok so it's starting to get hot so this problem is getting annoying now. If I am driving down the freeway my A/C works fine, but once I get in the city and am doing a lot of slow driving or idling on a day when it's like 80 or 90 degrees out my A/C stops blowing out cool air. One day I got a...

I am using the Pioneer AVIC-U310BT system. The Bluetooth on it is working really well for me. I have had a couple other decks with Bluetooth and this one is by far the best. I paid $250 shipped new on eBay for it. The only cons I have with this unit is that you have to purchase and SD card...

Any particular reason you feel this way? There are a couple of people on here saying otherwise...it would be nice to know why you have this viewpoint.

Yeah I've been thinking about giving that a try. I am using the 10w30 clean 5000 right now. I guess it wouldn't hurt to give synthetic a try for an interval to see what happens. I am using the motorcraft filter right now...is this filter ok to use with the synthetic oil? Should I consider a...

I'm using the Mobile 1 Clean 5000 right now. I just don't want to cause anymore issues by switching to synthetic and having it leak or something.

So is this something that should be considered bad? I am not an expert at this and have no experience rebuilding transmissions...so would not know if adding this and having the seals expand is a bad thing.

Ok cool, so I'm not the only one! Is there anything I should be looking for as to oil burning? I am considering trying synthetic...but don't want to try it if I am really loosing a quart of oil. That is a lot to be loosing and have heard not to switch to synth if you are going through a quart...

I have 170k on my engine and my OCI is 2500...It just seems strange that it would go through a qt in 2500 miles.

OCI?? It seems like there is something wrong if a qt is getting burned...i change every 2500

Awesome. Thanks for sharing your experiences. Anyone else have an experience they can share with this stuff? Negative experiences would be good to consider as well. I have read some reviews where people say it's too thick and actually messed up their transmission. Bob is the oil guy did a...

Yes, I change the filter also. I did not check the dipstick before the change, I checked it after and I am right in the middle of the min/max marks. I am just trying to figure out why I only drained about 4 qts. It seems a little odd. Does anyone keep track of how much oil they drain?

I dropped the pan, changed the filter, and 4qts of ATF in my transmission last month. I still have a rough down shift to 1st and a little shutter from 1st to 2nd if I am accelerating quickly from a stop. I have read numerous pros and cons on other sites. What are your opinions about this...

Ok I just had a quick question. I just got this explorer and did an oil change. Read that there is a 5qt capacity, drained the oil, dumped 5qts in, and refilled my 5qt container only to find out there is only about 3-4qts in the container. This is the second time I have done this. Just...
