I'm new to the idea of bleeding a cooling system as mine does not contain bleed screws, but this is for my wife's 04 Nissan Sentra. Just need some verification on the process.
This is from the owner's manual's DIY maintenance section.
From what I can tell, I drain the radiator (that's step 1), wash the radiator thoroughly, then refill with distilled water.
I plan to do a modified flush, such as disconnection the upper radiator hose and guide it off into a large catchpan, and run the engine while constantly adding in distilled water to the radiator until it is water coming out the hose.
After that, reattach the hose, add the anti-freeze and distilled water (if anymore is needed) when the engine is cooled, then run the engine till warm and I open the bleed screws until the flow of coolant is constant with no bubbling (correct me if I'm wrong please), and then close it.
Let it cool, top off, open the bleed screw again until the flow is constant with no bubbling (again, correct me if I'm wrong please), and top off one more time.
Is there anything I'm missing? How will I know that all of the air is bled out of the system? In the picture, is the left picture the block-drain and the right is the bleed screw?
