Tacoma 4WD V6-4.0L (1GR-FE) (2006)
Refrigerant: Service and Repair
REPLACEMENT
1. DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM
a. Start up the engine.
b. Turn the A/C switch to ON.
c. Operate the cooler compressor with an engine speed of approximately 1,000 rpm for 5 to 6 minutes to circulate the refrigerant and collect the
compressor oil remaining in each component into the cooler compressor.
d. Stop the engine.
e. Using SST, let the refrigerant gas out.
SST 07110-58060 (07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080)
2. CHARGE REFRIGERANT
a. Perform vacuum purging using a vacuum pump.
b. Charge refrigerant HFC-134a (R134a).
Standard: 570 to 630 g (20.10 to 22.22 oz.)
SST 07110-58060 (07117-58060, 07117-58070, 07117-58080, 07117-58090, 07117-78050, 07117-88060,07117-88070, 07117-88080)
NOTE: Do not start the engine before charging it with refrigerant as the cooler compressor does not work properly without any refrigerant.
This could cause the compressor to overheat.
3. WARM UP ENGINE
NOTE: Warm up the engine at less than 2,000 rpm for 2 minutes or more after charging it with refrigerant.
4. CHECK FOR REFRIGERANT LEAKAGE
a. After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
b. Perform the operation under these conditions:
-
Stop the engine.
-
Secure good ventilation (the gas leak detector may react to volatile gases other than refrigerant, such as evaporated gasoline or exhaust
gas).
-
Repeat the test 2 or 3 times.
-
Make sure that some refrigerant remains in the refrigeration system.
When compressor is off: approximately 392 to 588 kPa (4 to 6 kgf/sq.cm, 57 to 85 psi)
