Has anyone installed a block heater to CT 200h? There should be a hole in the block for the heater in 2ZR-FXE, but for some reason I can't find installation instructions for CT, only for Prius. There is also this Defa heater kit, but it isn't as effective as this hole type heater.
I got one when I bought the car new, it is an option in Canada so you should be able to order one and the Lexus techs can look up the install procedure on their system. It may even come with a diagram.
It's going to be in same place as the Prius because the motor is the same.
