There are EPA guidelines that must be followed whenever you deal with refrigerant. If you are not EPA certified, you should not be dealing with checking the charge of your unit. Having said that, here is the answer to your question The hose colors are typically: Blue for suction(low side) Red for liquid(high side) Yellow for refrigerant tank
Connect a gauge and freon can to the low side port of the ac system. Start the car and turn ac on high. Fill freon till the gauge shows full.
Using a gauge and the proper type Freon, connect to the low side ac port. With the engine running and ac on high, open the valve and let Freon flow until the gauge reads full.
Most automotive places have a freon recharge kits. http://www.bargainoutfitters.com/cb/cb.asp?a=230769&kwtid=203671 I prefer the one with the gauge on it and remember to attach it to the low pressure side. If you are doing a full take down and refill you will need some guages, a vacuum pump, and a recharge system. Because leting the freon out into the air is against the law.
Connect freon gauges and a freon container to the low side ac port of the 1991 Integra. With the engine running and the ac on high, open the freon valve to fill the system until the gauge reads full.
All fuses look good, compressor won't kick on, attempted to put freon in gauge on bottle went all the way over and would not take freon, any guesses? All fuses look good, compressor won't kick on, attempted to put freon in gauge on bottle went all the way over and would not take freon, any guesses?
Freon goes into the low pressure side of the air conditioning system. The attachment from the gauge used to put the freon in will only attach to the low pressure valve so it would be pretty hard to do it incorrectly.
The truck doesn't have a freon pressure gauge. That is a tool that the repairman/mechanic has.The truck doesn't have a freon pressure gauge. That is a tool that the repairman/mechanic has.
Connect a freon gauge and tank to the low side ac port. Start the engine and turn ac on high. Open the valve and let the freon flow until the system shows full.
To put freon in a 2000 F150 car, attach the A/C gauge set to the service ports. Add additional cans of refrigerant, as needed, to fill the system until the pressures are between 40 and 350 PSI.
Connect a freon gauge and the freon can to the low side ac port. With the ac running on high and the engine running, open the freon. Let it flow until the gauge shows that the system is full.
what is the pressure in the gauge with outside 90 degree temperature with freon 22
Freon is added into the low side ac port. Using the proper type Freon, and a gauge that works with that type Freon, connect the hose to the port. With the engine running allow the Freon to flow until the gauge reads in the ok range.
