If you have evacuated your air conditioning system, use BlueDevil’s Red Angel Oil injector to add Red Angel A/C Stop Leak to your system, ensuring lubrication and leak protection for your vehicle’s air conditioning system. Red Angel One Shot has the correct proportion of refrigerant and an advanced leak sealing agent that works as a lubricant until there is a leak. If you’ve discovered a need for more refrigerant in your vehicle, add BlueDevil Red Angel One Shot. The best way to ensure the long life of your AC compressor is to ensure that you add adequate oil any time you add refrigerant to your system. This is a difficult life for any pump or compressor so it’s important to take care of your AC compressor. If the R134 canister becomes too cold to handle, wrap it in a towel. Close the valve periodically to monitor the gauges. It also functions in a very high pressure system through a variety of temperatures and has to live in an environment that is constantly vibrating and sustaining impacts from your engine running and your car driving down bumpy roads. Turn the valve atop the recharging kits canister and let the R134a rush into the Impalas air conditioning system. The RPM your engine is turning, and the amount of cooling load on your air conditioning system will determine how often the compressor is engaged or disengaged.Ĭycling your AC compressor on and off like this unfortunately adds a lot of wear and tear. The compressor has a pulley and clutch assembly on the front to allow the belt to always be attached to the engine, and to also allow the compressor to engage and disengage with the clutch. If there is anything you would like to add, please feel free to leave a comment below. Leave the handle on top of the can in this position. Place the valve fitting from the recharge kit on top of the can, then turn the valve handle to draw out the valve stem until it pierces the can. ![]() But, using the info above about how and why a heater would fail can make it a lot easier. Place the refrigerant can on a solid surface. It can be tough to find why your Impala’s heater is blowing cold. The air conditioner compressor is usually mounted on the front of the engine block where it can be turned by a belt on the engine. Conclusion: Heat Not Working Chevy Impala. Your air conditioning compressor is the only moving piece in your air conditioning system but without it, the process wouldn’t be possible. From there it returns to the compressor to start the process again. Cabin air is passed over the evaporator, causing the air to cool and the refrigerant to return to atmospheric temperature. This expansion causes the refrigerant to cool below atmospheric temperature where it then travels to the evaporator which is inside the cabin of your vehicle. The atmospheric refrigerant is then allowed to expand through an expansion valve or orifice tube. It then is cooled back to atmospheric temperature in the condenser at the front of your vehicle. The refrigerant in your air conditioning system gets compressed by your AC compressor where it also heats up. Notice the pump and the hose will get hot partly due to the compression of the air. Have the AC system full cold, fan at high, doors open and engine about 1500 rpm. Place a stick thermometer in the center vent. This door is located in the ventilation system. Blend air door is the reason for drawing hot air to cold air in your car system. So, make sure that you check the compressor as it could be the reason why car AC not blowing cold air after recharge. If you install 134a yourself by adding to the system, only add an ounce at a time. And, when it senses any issue, AC is the first thing to get shut-off. This is the same principle that causes a diesel engine to work, and can even be seen when using a bicycle pump to inflate a tire. They will know that MFG specd amount is installed. As the gas is released, the remaining CO 2 in the extinguisher can expand, causing the fire extinguisher to cool off. You’ve probably seen this in effect if you have ever used a CO 2 fire extinguisher. Turned off the car and AC and spun the compressor by hand to make sure it wasnt stuck. The system began to move to the red so I stopped. I then began to put freon in but the compressor kicked on and off a couple of times but would not stay on. Whether you want to quickly reprogram the computer with a power programmer and Impala tuner or if you want to completely change how the sensors and computer talk to each other with a Chevy Impala PCM, weve got exactly what you need to get the job done. Replaced the manifold and put it on a vacuum which held steady for an hour after it shut down. Most refrigeration systems, including the air conditioner in your car, work on the simple principle that as a gas expands its temperature drops, scientifically called the Joule-Thompson effect. Thats why you need one of the Chevy Impala performance chips AutoAnything sells.
