I'm hoping that one of you forum members may be able to answer two questions regarding my 2008 Rx400h. Referring to the picture below, please note:

What type of fluid goes into the reservoir labeled A in the picture (the reservoir is on the driver's side of the inverter)?

Does this reservoir feed into the transmission cooler that is nearest the front of the car and which is forward of the AC condenser and the radiator? It looks like it does, but I can't tell for sure.

Thanks.

AtlPeter - I moved both of your postings today to the Hybrid Technology Forum. Since both questions are unique to the RX400h you will get more views and faster responses by posting there.

The pink fluid in the plastic reservoir is coolant (Toyota Super Long Life Coolant). That reservoir is for the inverter coolant loop, which is separate from the radiator coolant loop in the standard location behind the radiator. The transmission cooler is on the driver's side behind/below the driver side fog light, so you are probably describing something else. I'm attaching the repair manual diagram of the transmission oil cooler assembly that I'm describing.

Here's a photo I took of my transmission oil cooler for reference.

The coolant for the inverter goes to a small radiator in front of the Engine radiator. The transmission cooler is on the driver side bottom opening in the bumper as shown by Maseace.
