For lack of a better term, the passenger side battery came with a fiberglass cover around it. Now that the truck is going on eleven years old, the original cover has seen better days. I was going to just remove it and then thought that some engineer put that there for a reason so I called the dealership and they told me it serves the purpose of a heat shield on that side of the engine for that battery. They want 40 bucks for a new one so do any of you maintain this item or just toss it?<O</O

 

Subscribed. When I bought the truck passenger side had nothing. If price was reasonable I'd like to buy it a blanket like the one for the driver's side which came with the AIS.

 

Haven't had one on my truck for 3 years thus far with no ill effects.

 

I figured since I live in the high desert with summers in the 95-115 range for 4 months a year it might not matter.

 

Mine was acid-damaged when I got the truck in 2004, and I was able to find an OEM replacement on eBay real cheap back then.

I believe they are to keep the battery from getting too hot in the summer. It might not matter a lot if you have a serviceable battery and actually check it once-in-a-while. Use distilled water only, BTW.
