🙁 Hey, Just wondering what the deal is with those 3 hoses… The recharge kits at Walmart only have the 1 hose and you just pop it on the air conditining thingy and pull the trigger. :dry:
The blue and red are too the two A/C ports. One upper and one lower. The yellow goes back to the gauge set-up which also regulates the flow of the freon from the can into the correct A/C port.
The ones at Wally World, you just hook up to the correct port and squeeze the trigger.The set-up here is a professional mechanic set-up.
Hope that helps ya.
with this set-up, I have the ability to monitor high and low side pressures during the recharge.
blue = low side
red = high side
yellow = ‘maintenance line’TV advertises the devil out of those DIY recharge kits and those things can be a good way for a non-knowledgeable DIYer to end up with a non-repair at the least or a damaged car or their own body at the worst.
You do not have all of the required tools to do A/C maintenance.
- Remove any remaining refrigerant
- Pull a vacuum and confirm that it will hold for 30 minutes.
- Repair leaks. Pull vacuum again.
- Add refrigerant with leak detector.
Next year, when you have no refrigerant, get out a black light and look for signs of the leak.
