Re: replacing heater core/motor upgrade/ foam baffels

Hey Robert, I found out after I did my motor upgrade, that the Jeep dealer now sells a different fan wheel.
Their answer to the low output fan motor was to re-curve the angles of the fan blades. If you pick up one
of these new wheels along with the motor upgrade, then I think you will be glad you did.
After the motor upgrade, mine still does not put out what I was hoping. Keep in mind that you'll have to
open up the hole in the firewall that the motor fits thru. If I remember correctly it only needs to be about
a quarter inch (or less) all the way around.
Good luck with the upgrade.
