On other furums been discussing a 2006 Chevy HHR electric fan module?

You should have a lot more room than that.
Maybe a pusher would have been the ticket?
I was running a 18" flex fan on a two inch spacer and two 12" pushers on the front with the smaller 22" opening in the radiator support..don't worry I will get it in there...that torque strap really holds the engine down
