I would look for a good pusher fan if you want to keep the flex fan but they don't get the job done...I would get that HHR electric fan ..very strong ,quiet and cheap,,moves a lot of air....Think I paid around 59 $ for mine...as it's an oem fan it is dependable and is quiet and has it's own shroud.I was stuck in traffic one hot summer day for over an hour,,, never ran past t-stat temp.... the 195 t- stat is too high,,go 180. The HHR worked well for me while it was still 440 cid...started to run hot once I went 493 cid stroker motor..then I went to a 28 inch rad and dual fans from a full size Chrysler ...
