Can anyone tell me how to remove the positive battery cable? Usually there is a bolt to fasten the cable but here it's round. Thanks.

 

That looks like a cover on the positive cable bolt. Bet it will pull off.

 

Thanks. What size bolts should I buy? Is it a standard size for the Z06?

 

I will try that first but it's on tight.

 

Auto Zone. Mine looked like that when I bought mine. They are the same for all the side post batteries. Think I paid $4.00 for mine.

 

Are you saying that you bought a battery which had the same round top at the end of the battery cable and that you just pulled it off and there was a bolt underneath?
What did you pay $4 for?

 

Mes-can ratchet'll get her right off.

 

If it spins and does not loosen as you turn it, it is a decorative cover - otherwise it is a rounded bolt (but the latter is unlikely based on the photo).

 

When I get it off I will post back to let you know what it was.
In the meantime I have to go and take the smog test shortly so not removing any cables .

 

I bet you are correct.

 

Don't remember for sure, but I think the bolt heads are 5/16

 

I am just talking about the bolts. Never seen those covers before.

 

Look at it, it's SHINY, it's a cover.

 

Well rounded bolts get SHINY too, could be a cover

 

Does look just like a cover there. Should come right off.

 

A Chevy dealer did not have the side terminal bolts that are in the side terminal cables so he cut down a regular bolt. It punctured the NEW DELCO battery and the acid leaked onto the AC hose as well as the fender. The AC hose blew up from the rubber being eaten by the acid.
He LIED to my wife (GF at the time) and said that the acid could not eat into the hose. DAMN LIER.
I replaced the AC line, battery, and put the right terminal bolt into the wiring harness. This was eons ago and the side terminal bolts were few and far between. They are readily available now.

From the PIC it does look like someone put a round cap over the bolt for "decorative" ??? reasons. Use a pair of channel locks or vice grips and see if it pops off. If not unscrew it and replace it with a real side terminal bolt.

 

First let me thank all who ventured to guess what this part could be.
Being the curious type I had to find out what this mysterious shiny object was on top of my battery. Didn't want to wait until I had to change the battery and maybe get stumped.
I took a pair of plyers and started to twist slowly. It was turning but not coming off. I turned some more but nothing was being unscrewed. Couldn't be a bolt so I pulled as hard as I could. Finally top came off and I proceeded to drop it. It fell somewhere way down under the battery. Tried a magnet tool to no avail and reached underneath with the same result.
Since I didn't want to hear it rattling while driving or for some crazy reason making contact with the positive post, I removed the battery.
Couldn't see the damn piece. So proceeded to the next step and took out the four screws holding the battery pan.
Pulled out the pan and heard a sound hitting metal. Fortunately I could see the top so I picked it up and proceeded to reinstall battery.
I was planning on getting a smog test soon but now that I have taken the battery out, it looks like I will have to do some driving to reset the car computer. Good thing I have until November to take the smog test.
Does anyone have a similar story of replacing or changing a part then having to remove it because of dropping a tool or a screw/bolt?

 

Why did you want to remove that anyway? Never heard "if it ain't broke, don't fix it?" (J/K).

 

But that's the point, the top of the battery could have had a broken bolt.

 

Being the "curious type" I'm still trying to figger out WTF "plyers" is/are.
