I believe it goes in the front right side of the block on a 4.0 V-6. You have to remove the softplug, but before you do that drain the coolant and then you will be able to install the block heater.
Begin by training the water from your 2003 engine block. Remove the wiring harness from the block heater. Remove the block heater retaining bolts. The block heater will come out. Reverse the process to install your new block heater.
Backside of the engine in the center freeze plug :0)
Remove and engine block expansion plug. Insert the block heater. Seal the block heater. Attached the wiring harness to the block heater.
No.
Since approx 2003 the cord for the block heater has to be purchased separately.
There is a cover plate on the front bank of the six that could possibly be the mount for a block heater. I am not aware that Toyota offers a block heater. Maybe.
The block heater is located near the engine on most cars. This is true also for the 2003 Toyota Rav 4.
The block heater on a 2003 Passat V6 is located in the vehicle's cooling system. Not all vehicles are equipped with this aftermarket engine heating system.

The fuse for the heater AC blower in a 2003 Ford Explorer is located in the fuse box under the dashboard on the driver's side. Specifically, it is usually the 30-amp fuse labeled "HVAC" or "Blower" in the fuse panel. If you're unsure, consult the vehicle's owner manual for the exact location and labeling of the fuses.
