I'm impressed. As the original owner of an 01' Navigator, I can appreciate the difficulty and frustration of the repairs you've been making on your F-150. Thanks for posting these videos.
I wish you good results. This was one of the toughest repairs overall that I've done in the last 3 years. I'm proud to say it's still blowing cold as the 3 year anniversary of the repair approaches.
FYI The vacuum pump 1.8cfm is no where near enough. A 2 stage vacuum pump of 4---10cfm Using 4 cfm and under will take over night to evacuate . Using 5--10cfm will take minimum 6hrs These are approx figures as it depends on your moisture level . How do u measure moisture = with a micron gauge , 1000 microns is border line under 500 microns is best . Compressed air has moisture in it . Why do u need moisture removal ,moisture creates acid with old refrigerant and oil ,, moisture corrodes = moisture creates leaks ,, moisture gives incorrect pressures ,, better ac performance with a very dry system . Vac pumps will not perform without fresh oil and need to be micron tested Dedicated vac hoses ,,do a deeper vacuum ,, vacuum quicker Any vacuum hose thats used anywhere else is considered a dirty hose . Manifold gauges can leak vacuum very badly is why standalone vac hoses were invented
Can you check if the installed compressor is working before adding freon? I know that it can leak in the future, but just to try if it operates. I'm also trying to rebuild AC in one car. Thank you for so informative film.
The compressor can't operate with out refrigerant (Freon hasn't be used in cars for 25 or 30 years). The only way I know of to detect where a leak is coming from is to have the system filled with refrigerant with leak detector in it. Then a black light is used to see it.
From other videos.. The best time to check for leaks is during the vacuum process with gauges installed. After the 15 min vacuum process at -30inchHg. After 30 min. observe the gauge for any changes, indicating a leak.

Such attention to detail..
My hat is off to you, Sir..
Beautifully explanation for everybody.
Thank you very very very much.
Thanks so much for sharing this importan information was so helpful to me
Great video, I'm getting ready to tackle the same project on an 02 Ford Escape, lots of good info, Thanks
Great video. Explains everything and shows everything too
Another tip guys if you work on vehicles invest in line wrenches especially for brake systems
Very through. Great explanation. Having AC problems with my 2005 F150. Going to do it myself. Can’t justify $2000 shop repair.

@ No problems with my ac three years later. Thanks for watching and good luck with your repair work!
@@TheOriginalMechanic ok. well, that's good to hear...alright, take care
Great video thank u sir

Video treasure. Just curious if you opened the high pressure valve on the manifold? I noticed the high pressure reading on the manifold gauge.
I think I did. We need to open it to get a reading the gauge.
You've done quite a bit of work to this ford.... Coincidence, I don't think so....
Great job though.
