Now you need the Always on Coolant Pump mod LINKY
I plan to do the coolant pump mod on mine hopefully sunday.
This week, when i am home after work i am busy painting the airbox lid black and red on the hhr ss, the calipers red with black reflective HHR SS decals and i bought a spare ecu ($230) to do the aftermarket tune ($350) on it. 285+whp/290+wtq should make for a fun grocery getter.
