The instructions below include lifting the front of your Subaru, this can be very dangerous. Please make sure that you support the vehicle with approved stands, do not work under the vehicle while it is off the ground. Make sure that the hand brake is sufficient to hold the vehicle while you are working on it, if there is any doubt in your mind regarding safety STOP and do NOT PROCEED with these instructions until you are 100% sure that everything is safe.
Warning: The water in the Subaru cooling system can reach boiling point, be VERY careful when working on the cooling system, keep away from any open hoses, radiator or header tank when racing the engine, use extreme caution at all times!
