Air Sick Honda

courtesy of Bob, The Auto Answer Man


Bob,
My '95 Honda Civic has air pockets in the cooling system. The Honda Service Shop told me that it wouldn't clear up if I drained it or even went ahead and opened up the bleed screw. They told me I needed a container that would connect to where the radiator cap would be and the container would sit higher than the engine. Then they would fill it up with radiator fluid and let everything heat up and all the air pockets would be out. Somebody else told me that if I put the hose into the block for the cooling system where the bleed screw is, my problem would be taken care of. I was wondering if you could help me out because I don't want to get charged a lot and this hopefully could be simple.

A,
It's very odd that they would say that the bleeder screw would do nothing. However, they are correct in that you must get the air out from the highest point. One other way to attempt to do it is to park the car on a hill with the engine facing upwards. The hill (or vehicle ramps) should be high enough so that the radiator cap is now the highest spot in the system. Bleed the system normally using the bleeder screw, then top off at the radiator. You may need to repeat this procedure a few times.
Good Luck!
Drive Safely!
