Thanks, all!

calgaryhhr, my HHR starts also. However, it's my belief that very cold starts are hard on the engine over a period of time - any engine!

Canadian Tire was booked up solid today - and the service guy used to work for GM, and called up the "correct block heater" over $300!!!

I read the thread on block heaters and know that a person there used a "normal" one. I wonder if there is any knowledgable mechanic in Calgary or area that would know that the aftermarket heater is just as good as the expensive "name brand".

Will get it figured out!
