How to repair while troubleshooting an auto AC Compressor - Part 1 of 3 - Click here

How to repair while troubleshooting an auto AC Compressor - Learn to properly install a car AC compressor for your Auto AC System. AC hoses, AC lines, and AC condenser must be flushed properly and new car AC compressor is preferred for a good installation. Only use a remanufactured AC compressor as the last option if a new one is not available.  There are very few reputable rebuilders; if you can afford a new AC compressor, don't bother with the reman. 

Part 1 covers how to diagnose a car AC system.  It leads into how to install an AC compressor in a car.  Primarily, Part 1 will focus on how to uninstall the AC compressor and AC system components.  It goes over the proper tools necessary when troubleshooting an AC compressor, what to look for once the compressor is removed, and what to do before installing the replacement.

Part 2 of how to repair, install, and handle troubleshooting of an AC system series goes more in depth.  It shows exactly how a complete AC repair kit is packaged and what it includes besides the AC Compressor.  These parts are the AC accumulator (sometimes called the AC drier), AC O Rings seal kit, AC oil (sometimes called AC Compressor Oil), and an AC expansion device (sometimes called AC orifice tube or expansion block).

Part 2 will also walk you through the most important part of an AC compressor install, the flush.  Flushing the AC system can make or break your repair.  System needs to be clean before the install can proceed - no exceptions.  The video also highlights how to change the AC compressor oil.  How much AC oil you need depends on the car.  Each car is different.  Refer to your car's specific manual to know the type and capacity of AC oil needed in your compressor.

Part 3 of how to repair, install, and handle troubleshooting of an AC system expands on AC components.  Besides the AC compressor, there is the AC Accumulator and AC Orifice Tube.  Both parts are very important to maintain a healthy AC system.  The AC orifice tube is a pressure drop device.  The AC Accumulator/drier is a filter device.  Part 3 concludes with instructions on how to evacuate and recharge the AC system.

Any time the AC compressor is changed, the AC accumulator/drier must also be replaced.  The AC Orifice tube must be examined and it is recommended to replace it as well.  Part 3 shows you how to install each one.  Many do-it-yourself mechanics make a mistake in the final, evacuating and recharging stage of the repair.  The final step in the AC compressor install is also the easiest one to mess up.  Watch closely.
OEM and Aftermarket AC Compressor Switch - Click here
Instruction on how both replacement Aftermarket and OEM AC compressors will not come with Switch for the back of the compressor. Video compares a Delphi air conditioning compressor to an aftermarket compressor. Important to remove c-clip from the back of the compressor pump to swap switch and have a properly installed compressor for your ac system.
AC Compressor Delphi Clutch - Click here
This video shows how most clutches on new AC Compressors like DENSO can be rotated with ease. On the contrary, the OEM DELPHI HD6 and HT6 air conditioning compressors cannot be rotated. Aftermarket and OEM ac compressor auto parts are of better quality than remanufactured air conditioning compressor car parts. Use a certified car part mechanic for proper installation, repair, flush, and maximum cool air for your automobile.

Have a look at this brand new Honda CRV AC Compressor. This AC Compressor is compatible with the '03-'06 Honda CRV. When installing a new Honda CRV AC Compressor you should replace all of your Honda AC system parts including the AC Drier and AC Expansion Device or Orifice Tube. A new AC Kit will include all the AC auto parts you need to restore your Honda CRV AC system. You can avoid AC problems such as black death by purchasing a brand new OEM Honda CRV AC Compressor or brand new aftermarket Honda CRV AC Compressor and kit components including the drier, expansion device, oil and o-ring kit.
How to Repair DENSO AC Compressor - Click here
Electric DENSO ac compressors used on hybrid vehicles have a compressor inside the compressor assembly. One of the leading causes of ac compressor is a lack of lubrication, or the wrong lubrication being used. This is a brief overview of DENSO electric ac compressors, and what can happen with out prpoer lubrication. Without proper lubrication the compressor will start to disintegrate from ths inside, and debris will travel out of the compressor into the ac system.
AC Kit - Click here
An AC kit contains a new ac compressor, accumulator, expansion device or orifice tube, refrigerant oil and o-ring kit. Compare the replacement parts with the original parts to be sure they're the same. Make sure the compressor clutch has the same number of grooves and is the same diameter. Check to see if the mounting ports are in the same position on both the compressor and accumulator.
AC Compressor : Removing your AC Compressor - Click here
An ac compressor should be removed one step at a time. When removing your ac compressor you should remove the clutch wire and hose assemblies. Remove the ac compressor manifold bolts. Be careful not to get any dirt or debris in the hoses.
AC Drier and Orifice Tube - Click here
When you remove the ac drier and orifice tube you want to be very careful not to get any debris inside any of the hoses. Always use a backup wrench when removing any of the lines. Check for any excess metal shavings. Excess metal shavings are an indication that the entire ac system needs to be flushed.
AC Compressor Oil - Click here
When adding ac compressor oil you should empty all of the oil used in shipping first. The correct amount of ac compressor oil to be added is usually stamped on the compressor. The manufacturer recommends a specific amount of oil for an ac compressor.
AC Flush - Click here
Flush your ac system before installing a new ac compressor. Metal shavings or other debris from the defective compressor will contaminate the ac system. Shoot the fluid in one side of the compressor hose fittings to flush the system. Using shop air, push the fluid through the entire system and out the other port.
Air Conditioning Compressor Install - Click here
Air conditioning compressor installation is properly done after the system has been flushed. First put the hose manifold back on. Bolt the compressor to the mounts. Cycle the ac compressor by spinning the clutch plate several times. Install the compressor clutch wire, and install the serpentine belt.
Orifice Tube Installation - Click here
The orifice tube should have an arrow which points to the flow of the refrigerant. Make sure you're installing the orifice tube the right way. The installation is made easier by getting the o-rings wet with oil.
AC Drier Install - Click here
An ac drier is a critical part of any cars ac system. The drier serves as a filter for the entire system which captures debris and moisture. Any time you're replacing an ac compressor you must change the drier and flush the system. Debris and moisture in an ac system can destroy a new ac compressor which is why you need to purchase a new drier when you purchase a new ac compressor.
Evacuating the AC System - Click here
Evacuating the ac system should be done with both of the couplers installed and both of the valves completely open. The low side gauge should start to draw a vacuum. You should leave the vacuum on for 30 minutes to an hour. After you pull the vacuum on the system it's ready to be recharged.
Recharging the AC System - Click here
When recharging the ac system use a charging scale to put the correct amount of refrigerant back into the system. With the system at a partial charge close the high side and start the vehicle. After starting the vehicle and running it with the compressor off check the serpentine belt to make sure it was installed correctly.
