It was idling in my driveway yesterday I bleed it again this morning but haven't driven yet . If I remove cap with engine off to check level do I need to bleed again ?
Expert:  Pete replied 10 months ago.

You dont need to bleed it again if the cap is removed.I would run it until warm and then shut it down and allow it to cool then check and top off the engine coolant level.Do this more then once if needed but make sure it has cooled over an hour before removing cap to top off coolant.

The cooling fans for a hot engine usually do not kick on until around 220 to 225 degrees on some models so if your not reaching that temp this may be why the fans are not turning on without the ac being on.

If your only reaching 160 degrees and a new thermostat is installed and all the air is bled out then you may have a faulty engine coolant temp sensor needing replaced.

I guess my biggest question was about removing cap & rebleeding . It seems to have worked out /. So far . So I have 4 more questions this month - is that right ? Also I'm not going to have anymore charges on my card correct . I don't want a monthly bill .
