Acura Repair Questions? Ask a Mechanic for Answers ASAP
I am trying to understand what you have written. Sounds like your main concern is bleeding the air out.
First to answer why the reservoir did not change much. When there is a crack or leak in the system there is no pressure build up. Pressure and heat makes the coolant expand and when cooling a slight vacuum is created which would cause the coolant to flow from the reservoir into the radiator. This can not happen with a leak.
Doing the repair yourself, if you have the front of the car raised off the ground you can run it until the fans come on and then after it cools remove the cap and top up the radiator. You might have to do this a couple times but it will cause the air to raise to the top of the radiator.
You may not see coolant flow through the radiator which is normal and running it with the cap off coolant will overflow from the radiator as the car warms up. If you make sure the radiator and reservoir are full when cold you should be fine.
