Thank you so much. You seem to be very knowledgeable about things. I see you are a top contributor to this site. This is my first time on here. I love reading Click and Clack in the newspaper which is where I got the site name. We are checking on battery replacement costs with the Chevy dealer; they said you could drive the truck without the battery for a while until you got the battery replaced. Don’t know how long a “while” is but it’s probably not a long time. They said that the battery isn’t the only thing you have to worry about; components involved could also be very expensive plus labor costs. Thanks again for all your input. Have a great night.
