I've had many cooling issues over the years and decided to ditch the clutch fan and go electric.
I chose the HHR fan for the same reason many do... it's only $55 at Rock Auto and it sucks air like a jet engine.
The fan is controlled by the FAST EFI system.
Found the correct plug connector at a junk yard... bought a few at a buck each.
the middle one was too small a gauge so that was rejected.
Note.. the wire in the connector might need to be swapped to color code them correctly. The HHR fan will run backward if you cross up the wires.
It barely clears the front of the water pump... (I have a 4 core raditor) It wasn't enough clearance to work...
A number of people have made a simple modification to the back of the fan to make clearance and it sure enough works out great.
The "fins" you cut off don't seem to make any structural difference. One post on the net says they are cooling fins, but I don't know. The part you expose is not the spinning part of the fan... it is a solid housing.
I put some paper in the slot to help cover anything below and to help see what I was cutting.
clearance
After I finished the initial cut I realized I neede to get rid of a couple more bits to finish this off...
There are some tabs on the shroud base to remove to gain a little more space.
Note some cutting around the base of the shroud to fit the outlet radiator hose and the tranny cooler bungs.
The final product!
I've had no issues with cooling... this thing is amazing... and a BIG load off my mind.
Another thing off the list!
