How to Drain the Radiator on a 2006 Subaru Tribeca
- 1). Set the car ramps out in a spacious location where you want to perform the work.
- 2). Slowly drive the vehicle onto the ramps. Once in position, shift the Subaru into "Park". Set the parking brake and turn off the engine. Open the hood. Place a block of wood or a brick behind the rear wheels. Allow the engine to cool down for 45 minutes to an hour.
- 3). Unscrew the radiator cap. Turn it counterclockwise by one quarter turn. You should hear the radiator depressurize. Press down on the cap and continue turning until the cap pops out of the socket.
- 4). Take the drain pan and position yourself underneath the Tribeca. Locate the radiator drain cock (also called the "silcock" or "petcock") on the back of the radiator. The factory default drain cock on the Subaru Tribeca is plastic, but if the radiator has been serviced or the old drain cock was misplaced, then a substitute drain cock made of brass might be in place.
- 5). Set the drain pan underneath the drain cock. Unscrew the drain cock counterclockwise with the pliers. The radiator fluid inside will drain out. Move the drain pan, if necessary, to catch all of the flow. Tighten the drain cock clockwise with the pliers when finished.
