Special equipment for 2007 HiHy inverter coolant change?
 

My wife's vehicle referenced in the thread title is a little past due for changing the fluid in the radiator and the inverter. Can this be done by our competent, trusted mechanic without any special equipment, or does it need to be done by a hybrid specialist?

Thanks!

The radiator is just like any other car. The hybrid coolant system can be done by any good tech with a pro scan tool and a manual ( Usually Mitchells or All Data).

This is for 2012 model though. I doubt it's much different for yours. Yes, you can otherwise connect Techstream scanner simply to operate coolant pump. But it can be done without it too:

(c) When not using the Techstream: (1) Turn the ignition switch to ON (READY). *1 (2) Turn the ignition switch off and keep the coolant at the FULL level in the reserve tank to compensate for the drop in coolant level when the air bleeds. *2 NOTICE:

* Be sure to turn the ignition switch off before adding SLLC. * Do not work on the components in the engine compartment while the vehicle is in the READY-on state because the engine operates intermittent. (3) Repeat steps *1 and *2 until air bleeding from the coolant system is completed. Standard:

Air bleeding from the coolant system is completed when the noise made by the water pump becomes smaller and the circulation of coolant in the reserve tank improves.

HINT
Loud noise made by the water pump and poor circulation of coolant in the reserve tank indicate that there is air in the coolant system.
