Cooling system inquiry
So i have filled my cooling system and bled it properly multiple times. I know you fill it from the filler neck until the ast fills up then close the ast cap and never open again. My question is where does the coolant go once you open the ast cap again? I know your not supposed to but Its not coming out the filler neck. The overflow bottle is at the same level. Where is the coolant draining to? Why cant you open the ast? There is hose that goes to the ast to the filler neck. How can i make sure there is no air in it after i top up the coolant after a few drive cycles?

It shouldn't go out the filler neck when cold. The AST has a vent to relieve pressure on the system. If your over flow isnt moving you should be just fine. Just keep an eye on the overflow. Add as needed (which shouldn't be much or often)

Disconnect your throttle body coolant line. This will allow air to escape the system when you fill the coolant. Fill the AST. Cap it and fill the filer neck. Re connect the Throttle body coolant line.
You may have to do this twice. This should remove all the air from your system.
