However, if you're determined to do it yourself, here's a general outline of the steps. Remember, this is a *simplified overview* and may not cover all variations for your specific model. Consult a repair manual specific to your 1987 Toyota Camry for detailed instructions and torque specifications.
1. Safety First:
* Refrigerant Recovery: This is CRUCIAL. You MUST recover the refrigerant from the system using a specialized recovery machine. Releasing refrigerant into the atmosphere is illegal and harmful to the environment.
* Eye Protection: Wear safety glasses or goggles.
* Gloves: Wear work gloves to protect your hands.
2. Preparation:
* Consult a Repair Manual: Obtain a repair manual specific to your 1987 Toyota Camry. This will provide detailed diagrams, torque specifications, and crucial steps you'll need.
* Gather Tools: You'll need a variety of tools, including wrenches, sockets, screwdrivers, a refrigerant recovery machine, AC manifold gauge set, and possibly a clutch puller.
* Disconnect the Battery: Disconnect the negative (-) battery terminal to prevent electrical shorts.
3. Accessing the Compressor:
* Identify the Compressor: Locate the AC compressor under the hood. It's usually driven by a serpentine belt.
* Remove Related Components: You may need to remove parts like the serpentine belt, belt tensioner, and possibly other components to access the compressor.
4. Disconnecting the Compressor:
* Disconnect Electrical Connections: Carefully disconnect any electrical connectors to the compressor.
* Disconnect the Lines: This is where things get tricky. You'll need to disconnect the high-pressure and low-pressure lines from the compressor. Be prepared for refrigerant to escape even after recovery, so use caution. Use appropriate wrenches and sealant to prevent leaks when reconnecting. Take note of which line goes where.
* Remove the Compressor Mounting Bolts: Remove the bolts securing the compressor to the engine block.
5. Installing the New Compressor:
* Install the New Compressor: Carefully install the new compressor, ensuring it's properly aligned.
* Reconnect the Lines: Connect the high-pressure and low-pressure lines, making sure the connections are tight and sealed.
* Reconnect Electrical Connections: Reconnect any electrical connectors.
* Remount the Components: Reinstall the components you removed earlier, such as the serpentine belt and tensioner.
6. Recharging the System:
* Evacuate the System: Use your vacuum pump to evacuate the system and remove any remaining moisture or air. This step is critical to prevent damage to the compressor.
* Recharge the System: Using your refrigerant charging machine and manifold gauges, carefully recharge the system with the correct amount and type of refrigerant specified for your 1987 Toyota Camry. Refer to your repair manual for specifics.
7. Testing:
* Test the System: After recharging, test the AC system to ensure it's working correctly and there are no leaks.
Again, this is a simplified overview. Improperly performing this repair can result in damage to your vehicle, injury to yourself, and environmental harm. A qualified mechanic possesses the expertise, tools, and knowledge to perform this repair safely and correctly. The cost of a professional repair will likely be less than the cost of replacing parts damaged due to an improper installation.
