hey guys i have a 2003 hummer h2 and i believe i have the gm dealership installed block heater and was wondering if there was a bigger/more powerful block heather available? if so any links?
in alberta its been -40 the past week and i wanna be prepared next winter!
thx

 

I'd imagine it is not any Hummer specific and you would a LOT more by searching online for one for a 6.0 Silverado 2500 HD (2003 to 2007(classic) models).
