On climb out we received an engine bleed air caution message. After completing the QRH it directed to isolate that engine's bleed air which would disable its cowl anti-icing (which was being adequately heated according to the cowl advisory message) and to avoid icing conditions. I communicated the issue with dispatch and maintenance control. After discussing options there were no airports within our fuel range where we could avoid icing conditions and that diverting to [a nearby alternate] would be the best course of action both for maintenance and operations. I decided to reconfigure the aircraft as it normally is so we would have cowl anti-icing abilities on the descent. We made a normal landing and had the maintenance issue addressed with the line maintenance.This issue had been written up twice in the past week and apparently fixed. What was replaced must not have been the problem or it failed too.Possibly further maintenance scrutiny on writeups with a history with more strict preventative maintenance. That's a hard one because maintenance indicated they replaced an item believed to have caused the problem.
