Good stat for the price, beats drilling holes in the factory one and regretting it.
This fits my 2009 Pontiac g8 6.0L v8. It made the car run reasonably cooler in traffic and even 25 degrees cooler on longer highway drives. Completed a full drain and fill along with gm coolant and water wetter. Makes for a good summer upgrade. L it has been in the 95-100degrees f here and I need the car to stay cool in the stop and go. ... show more
