2002/2003 subaru outback does not have one!!!!!!!!
To install a block heater on a 1999 Subaru Outback, first ensure the engine is cool and disconnect the battery. Locate the engine block's freeze plug, usually found on the side of the engine, and remove it using a socket wrench. Then, insert the block heater into the hole, securing it properly, and connect the power cord to an electrical outlet. Finally, reconnect the battery and test the heater by plugging it in for a few hours before starting the vehicle.
No mention of a block heater in the service manual. It appears that they install heaters on the left side rear of the engine. Of course this type of heater plugs in to household power so if you have one it should be fairly easy to find the cord/plug and trace it back to the heater.
Since they no longer make a 2001 Subaru Outback, it depends on whether yours was equipped with one. It was an option so if you are asking if every one had a block heater, the answer is "no".
Do you mean where on a car is a block heater install or who do you take the car to to install?
