Question CT owners, there looks like two coolant bottles in the engine bay on the CT. One on the right and one on the left. Both seem to have pressure warning lid. Can anyone explain what both these are please?

Assuming you have a hybrid CT (your profile shows an IS250?)

Hybrids have two coolant circuits. The engine coolant and the power control unit coolant

Yes I have a 250 but was looking at a CT for a friend of mine so just curious what the two seperate coolant tanks are for. So does the bottles actually pressurise on these instead of a dedicated pressure cap on a radiator or something like the petrol equivalent? 

So I'm assuming both coolant circuits need servicing at the same time?

One is engine coolant and the other is inverter coolant and are both under pressure as are driven by the electric water pump as the 2ZR engine is not a belt driven water pump.They both use the same type of coolant are both serviceable via the service schedule.
