I like the mod to the metering valve, making it a coupling while keeping the lines intact when flushing. Great demonstration, thank you! The mess is part of it because having clean lines is key.
I did the same thing with the expansion valve, got 2 used ac lines attached, but I wouldn't use brake clean for the evaporator because you're going to smell it when all done. I used home Depot coil cleaner which is actually cheaper. This process works perfectly and the people that comment negatively obviously they don't have much experience 😁👍x
Am going to be honest, I'm surprised you release this video with so many errors, I mean that hose? High pressure? And you have it sitting on the bucket with no support.
No you can’t hard to reach. The expansion will be closed and also trap dirt. Since the Exp valve is in the way, no easy way to get free flowing solvent into evaporator.
Hey binh when you say drill out the hole bigger on the expansion valve. Do you just drill out the side walls of the hole and not touch the tiny little pin or do you drill out the pin inside the tiny hole also. Also what size drill bit do you drill it out into if you dont mind me asking.
@@TunerwithKids after drilling out the expansion valve. are you supposed to leave the ball and spring out to flush the system, or do you put them back in before you flush.

The 13:33 mark was the real deal. We've all been there. lol Good information man! -Glen
Use Coleman fuel. It costs less than half as much and does a bang-up job. It also evaporates quickly.

Yea trial and error. Most people I see online just dump it on the ground.
I saw the mess coming before it happened. How hard is that crwp to clean up?
Easy, it all went to ground. Should have clamped the hose to the bucket. It’s solvent based so wipe and it evaporates.
Why did you need to drill the Expansion valve? Cant you just flush out the evap from the suction and the HP line behind the expansion valve?

Remove the hex bolt at bottom and take the bearing and spring out. Drill through from that end. Use anything bigger that the existing opening.

Leave it out but out the heat bolt back.
Use acetone as flush
What not to do
I wish you could zoom in. It kinda hard to see whats happening exactly
Shouldn't this be titled "How NOT to Flush Automotive A/C Lines"?
Just make sure to clamp the hose to the bucket 😂
