I have searched and found only that the terminal is a 10 mm. Im finally going to get my car out of storage tomorrow morning. I would like to know what size socket ill need for the hold down to bring with me to change out my battery. the car is an hour away so i couldnt check my self. Thank you for any help.

 

I wanna say its a 13mm for the hold down bolt.

 

Thank you. Ill bring one up and down to be safe. but atleast i have an idea now, Thank you

 

Yea im pretty sure.Just bring a ratchet,extension and a 13 mm and u should be good to go.

 

just FYI, all the bolts on a cobalt are 7mm, 10mm, 13mm, 15mm, or 18mm. its probably a 13, but it couldnt hurt to bring a 10 and a 15 along just in case

 

Thank guys, Its been a long winter with out my car. Im so happy to finally get her back.

 

just bring a small socket set and then you have nothing to worry about. figure it out when you get there. no need to play the lottery.
