Was trying to find the "hidden" low pressure port on my 99 5.4. Your video quickly covered location on all engines, something I found no one else has bothered to do. Great job . . . . I have no doubt you have helped many with this.
Thanks for showing the port location of the 2002 F150 with 4.2L 6 cyl . That helped me verify the low side . Many show the port with cap on the V8 and is def in another location. Many thanks
Hey I’d appreciate some feed back I have the 4.2 v6 aswell and I feel like my truck is feeling super sluggish. First gear takes me to 10mph, second takes me to 30mph 3rd takes me to 40 and 4th takes me to 55mph, overdrive does 80mph no problem but the first couple shifts it’s taking way too long to move… the engine sounds fine and the tranny shifts fine .. idk what the problem is
Thanks for showing the location of the recharge port. I'd add you should have gloves and protective eyewear to save yourself from a world of hurt. And on our truck the a/c compressor was rapidly cycling on and off due to a low overall refrigerant amount, which caused the gauge to change from high to low pressure reading. When the compressor kicks on, the pressure drops too low and the compressor shuts off. Then the pressure temporarily increases to "high," triggering the compressor to run until the pressure drops too low again and shuts off the compressor. In that case, if the lowest reading you get (when the compressor is running) is at the low mark, the system doesn't contain enough refrigerant overall to meet the compressor's requirements. So you may have to and I definitely had to add refrigerant until there was enough refrigerant for the compressor to stay running. Then i could get a stable pressure reading which showed that the pressure was low (i think it was 20 psi). But knowing the desired low side pressure is tricky as it depends on the temp around the truck. And the low side pressure may normally even be be close to zero if it is cold outside with the a/c running, apparently. Ideally you should have a manifold gauge for measuring the a/c system's pressure, because it can measure both the high and low pressure lines and make sure both have proper pressure. And it's also tricky to determine the ideal high side pressure. I only used a low pressure line gauge built into my low pressure recharge hose (that is all you get with those "easy" diy recharge kits), but that is only a hack. I guess it's okay to get the a/c working again in a pinch. The proper way is to measure both high and low pressure lines using a manifold gauge which is rentable from auto parts stores. If you are using the manifold gauge to measure pressures or refill the system, never open the valve to the high pressure side. The pressure of the high pressure side can be read with its valve closed, and never open the high pressure valve as you would get a dangerous high pressure refrigerant coming out of the manifold gauge. (I would imagine it being a huge explosive release of vapor or freezing liquid but i dont know what would actually happen) This is all info i learned from Eric the Car Guy's ac recharge video.
Thank you for doing one with the 4.2L Engine. Wasn’t 100% sure where the port was until now. Had a good educated guess, but wanted to see it done first. I have an 02 as well. Love this old truck.
Thank you so much for posting this video! My brother has a 2000 f150 Triton V8 7700 with a propane system installed. So you can say I was a little turned around at first. After playing the video a couple times and making comparisons to his truck I had my aha moment remembering he had a propane system as well. With those extra hoses it makes it a little more tasking. Lol
So, I just replaced the compressor on my truck and had the system vacuum at a shop. He said he couldn’t get the compressor to turn on to fill it with Freon. But from what I’m seeing online it has a fail safe where if there’s not enough Freon it won’t let it turn on until there’s a Ohhh Freon in this system. All fuses and relays are good also.
Ok... would like to see and understand more about the hook up of the hose.. I haven't got a hose just yet, and understand there are certain refrigerate and hoses that have to be used, but guessing as this video didn't talk about that, the Auto Zobe guys will know and show me...
They all hook to the line the same way. I do have links in the description for the hose I use. They are universal for vehicles using R-134a refrigerant.
@@DirtRoadAutoRepair Don't get me wrong, I still found your video useful. It was just something I noticed. I know that ford made some slight changes after the 98 model year, I wonder if this was once of them
when I tried this the gauge moves between 25psi and 45 psi but a lot faster than it does in your video, like the click of the compressor turning on happens every couple seconds so the needle is basically always moving from one side of the green section to the other back and forth constantly. idk if you know what's wrong with it
@@DirtRoadAutoRepair I used the entire small sized can and it still does that, should I have gotten the bigger can? I guess I'll go buy a bigger can and see
