2007 Toyota Camry Hybrid Repair Question
Toyota Camry Hybrid Coolant Problem
First, how do I change the Synergy drive coolant? Is there a way to flush it out? Is there a process for bleeding it after a change?
Second, how do I change my tranny fluid? Will Dextron VI work in the CVT transmission? Is there any special things I need to know about changing it or is it like any other transmission fluid change?
Automatic Transmission Fluid Type
Change Automatic Transmission Fluid Only As Necessary.
Generally, it is necessary to change automatic transmission fluid only if your vehicle is driven under one of the Special Operating Conditions listed under one of the Scheduled Maintenance Guide or Owners Manual Supplement.
When changing the automatic transmission fluid, use only "Toyota Genuine ATF WS" (ATF JWS3324 or NWS9638) to aid in assuring optimum transmission performance.
Notice: Using automatic transmission fluid other than "Toyota Genuine ATF Type WS" may cause deterioration in shift quality, locking up of your transmission accompanied by vibration, and ultimately damage the automatic transmission of your vehicle.

ADD COOLANT (for Inverter)
HINT: Coolant (for Inverter) capacity: 2.9 liters ( 3.1 US qts, 2.6 lmp. qts.)
(a) Add coolant from the reserve tank.
(b) Connect the intelligent tester to the DLC3.
(c) Follow the intelligent tester screen to perform the active test of the water pump.
(d) While adding coolant so that the coolant level is kept between the FULL and LOW lines.
HINT: If the water pump operates without a sufficient amount of coolant for approximately 5 seconds, the protective circuit will activate to stop the water pump for approximately 15 seconds. If a sufficient amount of coolant is added, the water pump will start operating automatically.
When the operational sound volume of the water pump becomes small or when no air bubbles can be seen in the inverter reserve tank sub-assembly, bleeding of the coolant system is complete.
(e) After bleeding is completed, stop the water pump, add coolant to the FULL level, and install the inverter radiator cap.
NOTICE: Make sure to add more coolant than was drained initially.
