Re: blazer runs to cool

How cold does it get where you live? In my area it sometimes gets down to the 20's and I've never had a problem with my vehicles getting to operating temp or the heater not working.

I lived in Idaho for a few years and some people used the cardboard to speed up the engine warming but it was never for prolonged use. You might need to check other possibilities if it's something that just happened or if the engine never warms up to temp in long drives.
