When you’re fitting a replacement Subaru engine or Subaru radiator, it can be difficult to get the trapped air to bleed out of the cooling system.
You may already have your own system to bleed a Subaru cooling sytem, if not here are some ideas we found will work.
The instructions below assume that you have the proper proffesional cooling system bleeding funnel: if you don’t please click here to go to our online Subaru accessory parts website where you can purchase a kit for a reasonable price, believe us when we say this kit will save you a lot of trouble!
The instructions below include lifting the front of the vehicle, 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 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!
