Hey all,

 

I'm going to replace my battery in my truck tomorrow. And was removing it so I can turn it in when I pick up the new one.

 

The old one is the ac delco orginial, question is did you re-install that foam around your new batter? or just leave it off?

 

Thanks

I would recommend only reinstalling this foam if you live in a cold climate as it keeps the electrolyte from freezing or becoming a high consistency in cold weather. If the area you live in is hot then it will make the battery sweat and this shortens the life of the battery.

When the dealer replaced my passenger side battery under warranty they did not replace the foam, eventho I live in a cold climate.

 

 

 

I used to be a Toyota tech for many years, and some of our vehicles had plastic battery covers, such as the Supra. Most of the techs didn't re-install them, basically out of laziness. If the replacement battery is oversized, that's one thing, but if it fits, there's really no reason not to re-install it. On our trucks it's just foam rubber, so it's not that big of a deal either way. I just figured that the factory engineers found a reason to put it there, so I reused mine. I wouldn't lose any sleep over it though.

I replaced mine in my truck as well. They way it was explained to me is that the foam is there to protect the battery if it comes loose. It will not allow the battery to be punctured.

 

Besides, it the factory put it there, it is there for a reason.

IMO - If that battery comes loose, I think your going to have more to worry about than the battery. and ya that foam will protect that batteryfrom contact with the fan :D

Been down that road before when I took my Blazer airborne. The battery came loose and slammed into the headers and exploded... It was not a pretty site and had to be towed home...

Ouch! That battery acid must have reaked havoc under there! I can only imagine what the clean up and repair must have been like!

I was also told that the foam will catch any leakage from the battery and keep it from getting to the battery tray.

I hope there's no problem here with me posting a GM bulletin (copyright issues?).

 

Here's the definitive answer on what the insulator is for...

 

 

Battery Insulator Replacement #99-06-03-002 - (Mar 4, 1999)

 

1999 and Prior Passenger Cars and Light Duty Trucks

 

It has been found that the battery thermal insulator (1), installed on many new General Motors vehicles, is not always being placed back on the vehicle's battery (2) when the battery is removed or replaced. The installation of the insulator is essential for battery life.

 

When a battery insulator is specified for use on a particular vehicle, the underhood temperatures for that vehicle are high enough to be critical to battery life. Omitting the thermal insulator when installing the battery will considerably reduce the life of the battery by exposing it to higher underhood temperatures. Inspect the insulator for any damage. If the insulator is damaged or missing, replace as required.

 

Refer to GMSPO Parts Group #02.333 for the correct insulator.

 

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Blazer is all put back together. Another hard-won battle. The 4.3 is not easy to work on in such an archaic and narrow chassis originally designed for an inline 4.   My baffle issue is solved. I returned to the OG junkyard but was ready for a fight. The Blazer I had picked from was stacked on another vehicle so I had no idea how the heck I was going to get myself to working height to pull the front end apart. I had seen an S10 pickup on the ground so I was hoping the part would be the same, AND, I couldn't remember if the S10 still had a front end or not. But I didn't need to worry because it turned out to be my lucky day. The yard had just taken in a '98 Blazer, sitting right up front, on the ground, with room to work around it, and the front end hadn't been hit. The baffle and all the clips were factory perfect. I also scored another good handful of odds/ends and the whole shebang only cost me $20.   Got everything back together and it fired right off, sounds good, runs good. I've got a little coolant drip from a lower water pump bolt (D'OH!!). I did the right thing and snugged it down a little bit, and of course that didn't fix it. Yet again, I will have to soak everything in coolant to drain it down to the water pump, remove the bolt, and attempt to re-seal it. Nothing is easy on this truck. Nothing. But now all the radiator plastics are correct, snug, and fully functional. No more rubbing on the cooling fan. It runs, drives (took it for a 30 mile drive last night), no Check Engine lights, EGR is working, no vacuum leaks. We're getting closer...   The replacement wiper motor arrived yesterday. The tailgate was already disassembled and waiting, so I threw that in. It works! Sort of. Two new issues on the list. While the motor is strong enough and the gears aren't stripped, the wiper is hanging up on the bottom of the rear glass. This is the old style where the lower half folds down like a truck tailgate, and the glass swings up, and they meet in the middle when closed. The glass isn't sitting flush with the tailgate, now that I look at it. No rubber bumpers that I can see for adjusting, so I'll have to look at the hinge adjustment to see if I can correct it. Also, the washer/squirter just dumps fluid underneath the truck. The lines actually run inside on the floor so I'm guessing the tailgate is soaked at the rear trim and the line is disconnected. There's also a drain there....probably for this reason.   The leaky water pump bolt was really disappointing. JUST STOP LEAKING...OMG!!   Replacing the window motor and a rear door speaker are still to do, and then everything will work. I want this to feel like a "good" vehicle worthy of dropping $600 for new tires before I do. That means no leaking first. I hurt, and I'm kind of cranky, so I'll probably take a day of rest and do the water pump again tomorrow.

      Just saw on Jay Leno the new Scout. That’s the way it should be done.

      EV's have their nuances too. Best to operate the current type of lithium batteries between 20-80% charge. No real need to charge until you hit around 20%. Occasionally charge to 100% when needed. Longer term storage, battery should be 50-60%. At least those are the guidelines for our iX. We've been exceptionally good to the battery in that car...easy to do when you can charge at home like we can.   EV's lack so many of the rituals and so much of the visceral feeling ICE vehicles provide, which is why I think they're hard to accept for a lot of gearheads. They're fun in different ways, though.

      Winter Returned

      We have got a lot of rain lately, we needed it. Storms/lightning took out a floor fan. Dirt roads badly rutted from run off.   Power here is sketchy, whole house surge protector in the service panel and all electronics plugged into surge protectors. My biggest concern is my stereo, I've been an audio nut for years. $25 k in equipment. Stereo is on it's own special surge protector.

      Happy Birthday!  I also turned 72 this year.  In some groups I consider myself to be a young senior and in others I realize I have serious years behind me!  In June I spent a week in the hospital due to a blood clot following knee replacement surgery.  The hospital Doctor assigned to my care specialized in Geriatric medicine!  He is a great Doctor but the fact I required this type of specialized care  made me feel old!  Aging comes with new challenges but I sure appreciate getting older!  It most definitely beats the alternative!!
