I have heard a lot of guys singing the praises of the HHR fan set up.
My car has a BIG aluminum radiator and with a single 15 " electric , I thought I would be O.K.
Not even close.
The dimensions of the aluminum radiator are very close to the stock A body radiator , so I bought the HHR fan / shroud combo.
It covers the entire core and I went from creeping over 210 degrees to never going above 190.
If one will fit your deal , it is the best 50 bucks you will ever spend.
