Incredible. Saved me $250. Bought the $28 Chinese hose off Amazon. Size 14mm lower bolt and 10 top. I’m mechanically friendly but this made it possible!
Good video! My car is 2013 Hyundai Elantra GLS, currently at 125k. About a month ago it wasn’t blowing cold air so I decided to use one of this refrigerant cans and accidentally put to much in the system. Had to take it to a shop so they evacuated the whole system, changed the expansion valve and refilled it. It didn’t seem to work cause a/c was working but not getting cold air as it should. Now I’m having this issue with my RPM at idle when the A/C is on. It also have this little noise coming from the blower motor, but it only seems to happen when idling. Car runs smooth, but at red lights or stop signs RPM goes down and it becomes shaky and then this noise from the blower motor comes out (it only happens when a/c is on). Also replaced the throttle body, coils, spark plugs, MAP sensor, PCV valve because of this rough idle, and right now IDK what else to do with this. Dealer was asking for $550 for just a diagnosis and I don’t trust them anymore, so I’m running out of ideas
@@thatboiiraw First thing I'd check is the idle air control valve. The A/C does put a load on the engine, so idle fluctuations are normal, but it shouldn't seem like it's about to stall the whole time the compressor is on. Also, the radiator fan should also come on while the compressor is on.
Thank you. All mine leaked out do to having a hole in the line. I want to try switching it out and not paying $500+ just to replace the hose and fill it back up. But where do you get your oil yo lube it from?
You probably know this already or I missed it in the video. There can be a couple oz of refrigerant in the highside hose. You can unscrew the coupling that connnects to the highside but leaving it connected to the system but disengaging the valve stem. Then open your highside on your gauges so that all of the refrigerant from the highside hose will be sucked into the low side and you have less left in the hose. If you already know maybe this can help someone else :) Have a good one.
There are several reasons you don't want to just release the refrigerant into the atmosphere. 1. You don't want to breathe the stuff. I know it's supposed to be harmless, but it's a fluorine compound. 2. Uncontrolled release may include refrigerant oil. 3. It's bad for the environment. 4. It's against the law and the EPA can fine up to $37500 per day. Yes, it is necessary to vacuum the system before adding refrigerant. You don't want any moisture or oxygen in there to corrode the system. Air will also significantly decrease the performance of the AC.
Ok I understand that releasing the freon is bad for the environment but what if the case is a bit different, suppose I hit some thing under my car like a small bolder and the hose was ripped off with the metal coupler still attached to one end, could I just replace the hose and buy new coolant and be ok.
You also would want to replace the filter/drier or accumulator, whichever your system takes because the dessicant will be saturated with moisture due to being exposed to the atmosphere. Then vacuum the AC system for around 45 minutes or so before charging up with the right amount of refrigerant by weight.
