Good day, I happened onto your video as I purchased the same tool to replace low side core. I’ve tried about 5 times and it just will not bring it out. I put vacuum grease on the end of the tool, but the shut off will not turn 90degree. It’s a 2017 expedition. It’s almost as if the core is not clearing the ball valve
if you can pull the plunger out and the ball valve closes normally it could mean your valve core is in the way of the ball valve closing. sometimes because of pressure you may not notice the plunger can be pulled back a bit more. If you are able to thread the core back in, pull the plunger back all the way and confirm your ball valve is working normally. do you feel the tip of the tool inside catch the head of the core? I pointed out in the video that the low and high side have different sizes depending on what you need and they are interchangeable. once you snap onto the port be sure you ball valve is open fully before pushing straight down carefully. once fully plunged, give the tool head a slow turn until you feel the tool fall into the grooves where it is now tight onto the core. slowly break the core free and un-thread it slowly. the pressure from you system mixed should be enough to push the core out and you can feel the pressure push the plunger back. pull back until the plunger holding the core can't come back anymore then close the ball valve. at this point the core should clear the valve and hold the pressure in your system while you unthread the plunger to replace the old valve with a new one.
@@TOOL_TECHNICAL I tried that as i said, several times. I won’t give up. I’ll follow up as soon as I can. I know the valve core unthreads. But, thanks for additional info.
@@carlosgarza8936 if anything what you could try is threading the core back in fully. turn your expedition on and let the a/c high run for a 2-3 minutes to build a bit of pressure to help the core be pushed out. definitely keep me posted !
Got my whole kit for $20 total and no need for any grease to add at ends as mine is the upgraded version that grabs the valve cores firmly! Came with 10x R134a valves (Low pressure) & 10x R12 valves (High Pressure), 8 extra caps and 20 o-ring rubber seals + extra removal tool with carrying case ... Worth every penny! 😁
The tool is nice. All should be informed the high and low pressure side should have the same RESTING pressure. This should only take about 10 min after turning system off. But wait and it’s best to verify with gauges. If the high side doesn’t drop and low doesn’t rise to equal each other then there is a restriction somewhere (expansion valve, condensor, etc) Good safety precaution and diagnostic note.
thank you for sharing! I did make that clear from 10:35 - 11:51 also noted humidity and summer temperatures cause that pressure to decrease slower As for the gauge yes you should be verifying pressures as I've shown in ruclips.net/video/pa9X-onIHz8/видео.html while doing diag for this same vehicle. 09 honda civic hybrid
@@JStorm24 The hoses on a manifold gauge set connect to the high and low side ports respectively. No they do not attach to the tools used in this video which are only to change the valve cores. It is important to note when checking pressures that you use a bit of refrigerant connected to your manifold and purge air in the lines so that atmosphere and moisture aren't introduced to your sealed system.

@@TOOL_TECHNICAL That would be another good thing to do if it fails again. Thank you
Just following up, were you able to get that valve core out? @carlosgarza8936

@@Trump-The-GREATEST from the same brand? And the grease isn't necessary just a tip for those with stubborn valve cores

My question is does the hoses attach to them?
