Replaced Coolant Tank Reservoir Bad Bleeder Valve?

[donaldoc3]

After replacing the coolant tank reservoir on my 2000 cab I started the "bleeding" process of lifting the bleeder valve and running the engine to operating tempearture. After it reached operating temperature, I tried to release the bleeder valve but it does not return to the "closed" position. Do I need it to cool down? or should it have returned immediately?

Let it cool down, the little plastic post will stay up for while if you where running up to temp.

Thanks Izzy, i'll let you know what happens. After putting the tank in the last thing I wanted to do was take it out for a faulty valve!
