Car running hot would it be a good idea to switch to HHR fan?







I have a spal 16", 2360, straight blade, puller, VA18-AP6-41MA with a shroud. I have a stock mechanical water pump, 50/50 coolant mix, 35 total timing, 20lb cap summit radiator, 180 stat with 3/16 hole drilled. The car runs around 200-205 and wont cool down even at highway speeds.

Swap to 160 stat?
High flow water pump?
Water wetter?
Would the HHR fan cool better? part #15817306
Anybody running one?
