my little 08 aveo
dosnt really warm for anything. good and bad. these last 2 days it has been below freezing here and my car doesnt seem to warm as much as it did when it was in the 40's and 50's. just today it was at the normal operating temp, parked it and sat in the car before work and the temp needle started dropping. ive never had a car this small with this small of an engine.
so i google make car warmer and turned up a result in a reply to the same question on a message board or something of the sorts. it was said to use some cardboard like from a beer box to block off half of your radiator. is this a good idea or no? any other ideas how to make it warmer in the car?
