Re: any way to bleed cooling system
No heat at all sounds like more than an air bubble (possible leaking head gaskets). Ford recommends filling with a RadKit Plus to make sure it is free of air pockets - but they are expensive! As Heavy Assault mentions, I have found that you can "burp" it a few times and it will eventually clear of air bubbles, if that is all that you have going on. I let the system get fully warm and then CAREFULLY vent the degas bottle (remove the cap - the quicker the better - as long as you protect yourself from possible liquid spray). SAFETY TIPS - Make sure that you have a proper coolant level (at or below the minimum level) so that you will be venting off gas and minimizing the chance to blow out hot liquid. Even with a proper coolant level, put a thick/heavy towel over the cap and top of the degas bottle to protect yourself and hands from liquid spray when you open it.
With typical 8-10 psig pressure and proper level, it should not spray out much, but the cap might have failed and it might be holding more pressure than 16-18 psig. Also, if there is a large air bubble internal to the system, it could cause it to vent more violently.
Then let it cool off and check the level. If you are removing air bubbles, you will see the cold level drop.
It will take multiple times of doing this to clear a system of air pockets.
