Howdy folks, I live up in Colorado, just looking for the Part No. for the Block heater for an 03-05 (or third gen equiv.) Coolant Heater/Block heater so I can go grab the part from GM/Chevrolet and get it installed sometime before the snow up here @ the resort starts covering up my car.

Thanks in advance

Also, anyone know about how much it will cost?

Cheers
~D.
