Coolant System Bleed/Purge Air Procedure

[samcrac]

I just installed a new radiator and some new hoses in my FiST because the originals were damaged in an accident. I filled the reservoir up with water and turned the car on to make sure some of it cycled through the cooling system. On my initial drive I drove the car for about 5 minutes and a couple of miles before all the lights came on the dashboard and showed the car was overheating. I stopped the car and pulled the plug on the top of the radiator (doh! shouldn't do that while it's hot) and a lot of steam rushed out. Anyway, I was wondering if there is an appropriate bleeding procedure for this since I want to fill the car up with Motorcraft Coolant + distilled water and don't want to risk having to flush the radiator and lose all the new coolant when I'm done. I'm assuming the car overheated because of the system not being properly bled since all the major components were replaced. Thanks for your help.

This is the same for all vehicles. Flush run with cap off low idle, cycle everything add coolant as required. Repeat. It's not like an oil change you need to make sure there is little to no air before driving around.

coolant venturi for the win. It sucks all the air out and creates a massive vacuum and then you put a hose in a bottle of coolant and magic. Your coolant system is filled and there is no air. Worth its weight in gold.
