Properly recharging the freon (R-134a) refrigerant in the air-conditioning process in your 2001 Toyota Highlander is required after any repair that results in a loss of refrigerant. A vacuum pump, to remove any moisture trapped in the action, and a locate of A/C gauges are required to organic this project. These tools are available from a well-equipped Car parts store for pay for and, in some cases, may be available in the store's loaner factor programme.
Instructions
1. Quick the valves on the front of the gauge meeting. Attach the hoses from the gauge locate to the advantage ports on the air-conditioning lines. In the Highlander, the ports are located on the passenger side of the engine compartment, near the firewall. Remove the unhappy plastic dust covers and snap the hose ends onto the ports. Twist the stud on the hose ends clockwise to regulate the overhaul ports.
2. Screw the hose heel of the treacherous assistance hose in the centre of the gauge locate to the inlet on the vacuum pump. Plug the pump into an electrical Issue and turn the "On/Off" switch on the pump to the "On" position. Extensive the valves on the gauge meeting and authorize the pump to dart for one date to vaporize and remove all moisture from the process. Accelerated both gauge valves and turn the pump off. Disconnect the low hose from the pump and screw the can tap onto the hose in its habitat.
3. Turn off the engine and disconnect the hoses from the A/C system. Reinstall the dust caps and test-drive the vehicle to verify the system cools properly.
Alpha the engine and locate the A/C controls to maximum cooling. Ticker the gauge pressures until they settle and stabilize. This indicates the can is empty. Close the blue valve and remove the can from the tap. Install another can in the tap and open it. Open the blue valve and allow that can to empty into the system. The A/C system in the Highlander holds 24 ounces of R-134a refrigerant. Each standard-sized can is 12 ounces, so the Highlander will require two cans.
5. Screw a can of refrigerant to the tap and expansive the can with the tap. Airy the blue-colored valve on the gauge assembly To admit freon to flow into the process until the impulse stabilizes. This prevents Exorbitant compressor clutch wear during the course.4.
