1996 Chevrolet Beretta. Where do I add freon?


attach the recharge kit to the valve under the blue cap on the lower front of the vehicle, between the engine and radiator. The hose end from the kit, will only fit the proper size fitting on A/c system. The right fitting is there! Good-Day!

Is the fan suppose to come on whenever A/C is turned on? & can u install freon if the fan isn't running?


Yes, the fan should be running when the A/C is turned on. Install freon in the suction line with the compressor running. The fan may shut off after the condenser coil cools off because of a temp sensor on the condenser coil. You do not want to add too much freon, because higher suction pressures correlate to higher evaporator temperatures, which result in lower cooling performance. As long as it blows cold air, you do not need to add any more freon to the A/C system. I do not know why the spark plugs would misfire with the A/C running. There are four main causes for engine misfires. A loss of spark, an unbalanced air/fuel ratio, a faulty fuel injector and a loss of compression. It could be bad spark plugs or bad spark plug wires. A leaky fuel line, weak fuel pump, leaky or clogged fuel injector can cause misfiring. Leaky vacuum hoses, a busted exhaust valve or a blown head gasket can cause misfiring too.

What is the correct pressure for freon in AC unit and what is the color of the cap where you add the freon?????


The charging port cap is usually blue, The charging fixture hose will not clip onto the wrong port, so you really can't mess that up. the pressure of a system as measured on the low side hose should be about 28-32 PSI with the system stabilized and engine at operating temperature.

Need to add freon to my 1997 gmc sububan diesel. Need to know which is the low side.


The low side is the smaller valve, and if you are using a one hose system to charge it then that fitting will only fit the low side valve which is the small one, good day.

I need to add 134 to the system, it's not blowing cold


First of all, you need to check if the belt is tight, if the electric clutch is turing on and off with the switch, and if there are bubbles in the receiver/dryer cylinder sight glass.
If you add so much freon that the pump has liquid in it, it could blow it up.

But you buy freon with a short hose and valve.
Wear eye protection and gloves.
Then you attach the can to the valve on the side with the thick hose.
There will also be a valve on the skinny side hose, but do not attach freon there. That is only for measuring with a gauge.
The open the freon valve and start the engine and AC.
If the can frosts up, you can put it in a bowl of warm water.
Watch the sight glass until the bubbles stop.
Then close the freon valve.
Turn off the engine and AC.
Disconnect freon can.
