On other furums been discussing a 2006 Chevy HHR electric fan module?
I picked up my spare 26" downflow radiator at my storage today...
The HHR fan does not cover the entire radiator...and it would take some work...but I will look into it farther....I put a piece of aluminum stock behind it to show one option to mount it...it would be at 3 1/2" from the radiator core...I need better than that because the front snout of the pulley is at 3 1/3"...not giving up yet...
