Hello,

I just replaced my AST with an aluminum one, and afterwards the coolant buzzer went off. I believe it's because there is air in the system, but I am not experienced enough to know how to get it out.

If the buzzer is going off, you've got air at the high point in the cooling system. If you open the upper radiator cap (the one to the left of the alternator) it will probably be dry in there. Fill that sucker up. Also double-check for leaks.

Getting all of the air out of your system can be difficult. My method:

Jack up the car slightly on the drivers front side. Disconnect the coolant line behind the throttle body. Slowly fill the filler neck. This will force some air to escape thru the TB coolant line. If coolant starts to come out, reconnect the line. fill the filler neck all the way, and cap it.

This should remove most of the air in your system. Drive it, let it cool, and check the filler neck. Filling the filler neck a couple of times should now get all the air out.

But why the TB hose? Why not just jack the front end of the car so that the AST will be the highest point of the coolant circulation and start the car, you will see pockets of air flowing out. until it stops, then refill it in the position it is. (I used this technique before and never had problems) Cuz sometimes,(on certain cars) the heat rad is higher then most components and a pocket of air can be held there.

The TB hose is pretty high already, and it allows a secondary source for the release of air. Regarding the earlier post, I meant to say that the AST should be filled slowly first, then the filler neck.
