Ac low pressure switch

coolant has nothing to do with the ac system
coolant goes in a radiator
gas goes in the ac system and should be only installed by an accredited ac specialist shop using the correct equipment
If you have to add gas then there is a leak in the system
second point , when you turn on the ac compressor , and start to add gas ,when the gas pressure is sufficient then the ac compressor will switch on
Best to have the specialist do the job for you

How to recharge ac

There are many ways to recharge an ac system but to do it correctly is a bit more in-depth. You can read the ac tag under the hood of your vehicle and purchase a can of coolant then hook it up to the low pressure side as shown on the can. Start the engine and follow their instructions. If you have a leak you should add UV dye to the system to locate the leak then repair as needed. To recharge system I recommend purging the system to a proper catchment contaner, recycle the refrigerant as required. Put an ac manifold on the high and low ports of the ac system (they are sized to only fit in the proper location) then attach a moisture removing vacuum pump create a vacuum in the system of 20lbs at sea level or more. Close the high and low pressure valves and disconnect the vacuum pump connect the refrigerant to the vacuum line, start the vehicle, turn on the ac (fan on low) add the amount of refrigerant that your vehicle tag requires.

1976 Cadillac ac not working

You can only add to a system that is under a vacuum,
unless you know what your doing
Need the proper manifold gauges,can't use those
store bought cans with the hose,you will let air in & ruin things
Have to check for leaks,if you know your low on
refrigerant, you have leaks to fix first.
The compressor clutch isn't coming one because
the system pressure is too low,you know that

I need to find low pressure port on 1999 Labaron LXI for recharging ac coolant

Without A/C system theory & some training,
I would say no. Leave it to a mechanic with
the correct equipment

You can not just add very well with those wal mart
a/c kits

You have no way of knowing how much to add, without
a manifold gauge set attached to vehicle

If you need to add, you have a leak that needs to be
repaired & your poluting the atmosphere until the repair
is completed

Need to locate the electric fan fuse for my jeep

doubtful fuse blown,but Make sure all the air is out of cooling system,by bleeding it out or filling coolant reservoir ,and radiator full.Then run engine to about 210 degees,or close,then turn engine off.Wait about 30 to 40 minutes,and reservoir should have dropped in the level of coolant.Then add more coolant and repeat as nessasary for the fan to come on.Then make sure the fan goes ogg on it`s own.Then you will know the system is ok.Do this with ac,and heat off.

I have to keep putting water in my car

IF the leak solution was for the radiator then you may have holes in locations you are nit aware of or it may not be enough and you may need to have the radiator replaced. You may want toc heck the radiator cap if it still seals properly as steam may escape from it where it should be recycled back to the cooling system. Check the clamps of the hose and if there are water leaks from the engine which may indicate bad water pump. If you have white smoke coming out of the exhaust you may also have to have the head gasket checked out as you may be burning coolant.

How do I add coolant to the air conditioning system of my 2001 Hyundai Elantra?

You need to locate the low port on the AC.

You recharge the AC connecting to the low port.

You find the AC low pressure at the top of the compressor. Near the compressor you find two ports, the high port and low port.
You can follow the compressor line to reach the port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports , often covered with plastic caps. Only one of the pipes will be cold, the line that is cold will lead you to the low port.

AC doesn't cool

2003 should use R134a coolant for the A/C system. But if it is not gettign cool either you have a leak and/or something has broke.

Either way adding more coolant will not help as if it leaks it iwll just leak back out. And if somethign is bad adding more will over charge the system and maybe break other things.
