TK826 has a pic of a shield that looks nothing like above, but was stated to be a police shield. TK, can you post a pic?
None of these had a battery heat shield. Marin County MHP blue Fury king-of-the-hill buffalo fire department 440RULEZs e-bay-huey-to-luuk cop-cars-online museum missing-alternator-bracket 74 CHP
Well, at least none had a heat shield recently.
So it seems we have a police brochure, and some knowledgeable people stating that 74 CHP monacos always came with a heat shield. But we've never seen one. Why? It seems strange that none of these cars would have their shields.
your friend in learning the truth about monaco battery and battery accessories, arthur
Mine does have one, previous owner Dave did not have it installed for whatever reason (can't remember), he sent me a care package back then as stuff resurfaced in his garage. By that time the tremendous heat from the 440 had killed one battery and the next one was sort of medium rare already...
Will take photo asap and post here, say in a year from now?
Your friend in fine cooking,
PS: The one from the pic above, IF it is a replica shield, it's a good one, mine doesn't look much different. Can pull it out and take more detailed pics of course.
He talks about the shield being only on one edge. Here's the pic in the parts catalog:
that shows it only on one edge. And this pic looks like the pic of the red monaco. The parts catalog shows that the heat shield came ONLY on monacos with the 420A battery (and not the standard 380A battery)
I'm guessing the red monaco had the "F25" option.
Which got it the bigger battery, which automatically got it the heat shield. Notice that F25 came by default with the 440 engine.
This car didn't have the 440: > The 400 CI automatic V8 engine is full loaded with a tow package > including heavy duty radiator, transmission cooler, and a hitch.
so I think they must have ordered the F25 specifically. But who knows. The parts catalog says "420A", but F25 says "440A".
So back to police options. It looks like police cars could get the heat shield without getting the 420A/440A battery. Not only could they get it, it looks like they always got it. But not so fast. I think maybe the police brochure is wrong, and police cars always got the best battery, and the shield came with it.
440RULEZs build sheet shows F28 for battery:
Looking in my Govier code book, F25 is "70 AMP BATTERY-H.D. 440 AMPERE-RED CAP", and F28 is "70 AMP BATTERY-POLICE".
It would be weird if cop cars always got the heat shield, but they didn't get the best battery to go with it. Or maybe the bigger battery only came with the bigger alternator.
Either way, I can believe that cop cars always came with the shield. But if so, why haven't we seen more of it? I guess because it's so easy to remove (attaching basically just on one edge), and batteries always need replacing, so it gets fooled with often, that it doesn't usually stay with the vehicle over the years.
I wonder if the police battery looked the same as the heavy duty civilian "red cap" battery, and if a "red cap" battery looked the same as the fallapart monaco:
The option list shows that the biggest battery came automatically with a 440:
and the parts catalog shows a standard "size 24" battery, with a "size 27" battery for the 440:
The parts catalog has some pics of what the batteries looked like:
and has the info on "24" and "27" batteries:
Maybe the "F25" option (which came by default with civilian 440s), was the 420A (cranking) A-27 battery, and the F28 option (which came with 440RULEZs CHP 440) was the higher performance 27 size battery: SC-27.
My Fury has F28 (ultimate battery) on the build sheet, and not on the fender tag. And my Fury has F15 (Leece Neville alternator) on the fender tag and on the build sheet. I bet 440RULEZs car is the same way.
So it seems options are: 1) all cop cars got the ultimate F28 battery 2) all cop cars with a 440 got the ultimate F28 battery 3) all cop cars with a Leece Neville got the ultimate F28 battery
We'd need to find a cop car with a 440 without Leeve Neville, and see what battery it had. Like Marin County. I don't have much of a build sheet, but I have the alternator and battery section:
440RULEZ's above. Marin County below.
You can see that I had alternator: F18 battery: F28
So I had the ultimate battery, like 440RULEZ, and I got it without ordering it special on the fender tag (I'm betting just like 440RULEZ), and without the Leece Neville alternator.
So we're down to: 1) all cop cars got the ultimate F28 battery 2) all cop cars with a 440 got the ultimate F28 battery
I guess we need a cop car without a 440 to know for sure.
Current thoughts: All cop cars came with battery heat shield. If a cop car came without a 440, we don't know what battery it got. If it came with a 440, it got the F28 battery automatically.
From the black-and-white battery pics, it doesn't look like the lid/top is a different color. So it looks like the blumo battery is aftermarket (and is missing the shield). I think "red cap" is different than "red lid", and looks like this:
The police brochure shows that k-code VIN cars got the 380A / 70AH battery and shield:
and that A38 cars got the same 380A / 70AH battery and shield:
All the cop cars that we currently have info on (which is just 440RULEZ CHP, my Fury, my Marin County), all got the F28 battery, which I'm guessing is the SC-27: 515A battery.
And then we have this statement: > The Valiant did lose out on some features. The 500 amp battery > with long-life heat shield was reserved to the B and C cars;
Now that might mean > the 500A battery was reserved for the c-body cars - but only > c-body cars that earned it through some selection of options or > motor but it seems to imply > the 500A battery was on all c-body cop cars
And by 500A battery, I think they mean F28, which I think means the SC-27 515A battery.
This place: shop.turbostart.com/Collector-Car-Series_c2.htm has some reproduction Mopar batteries (green cap, yellow cap, red cap), but all are AGM and don't need to be filled with acid. None of their part numbers match those listed for a 74 Monaco, but it looks like the same concept.
So maybe the 75+ thermoguard is rare today, not because it was produced in low numbers, but because most everyone threw them away.
I see the catalog actually has two different thermoguard part numbers for 75 (without oil cooler, and with oil cooler).
I would have guessed that 1974 civilian cars didn't come with shield standard, since we've only seen one car with it. But that logic doesn't seem to apply, since we know that 1975+ cars all came with shields, and we haven't seen any civilian cars with their shield.
I think the only hint is that ma mopar was just beginning to figure out that they needed some type of shield in 1974 (hence the new style plastic shield in 75+) and there wasn't time to make it standard in 1974. And the parts catalog (wrong as it is at times) seems to show that in 1974, dodges with 380A batteries didn't have a shield.
1974: ... Cop cars got the heat shield (either because cop cars had whatever civilian options got it the shield, or because it was just added on extra for all cop cars).
It looks like it was just because they were cop cars:

Some interesting thermoguard info, discussing how the shield doesn't fit with newer batteries. This would explain why we haven't seen any 75-77 civilian monacos with them. So a 1974 civilian car, with the big battery option, would at least have the option of still of having the shield still being installed on the car today (as it would fit with sealed batteries available today).
As the 1975 Factory Service Manual page above clearly states, aside from the VL (Valiant/Duster and Dart) line, the ThermoGuard was standard equipment on all Chrysler Corp. products beginning that year. I know Cordobas had them through the last of the B-bodied cars in 1979. (Note: 1978 and 1979 models incorporated the windshield washer solvent bottle into the plastic battery heat shield).
This was a standard equipment item, installed at the assembly plant, on every new Cordoba built.
FYI: Part # 3874151 appears in the 1977 parts catalog as well, and was used in production until 8/6/76. After this date, the number changed to 4005059.
The ThermoGuard is a part that is often missing today. Our cars started life with batteries that still had serviceable cells. In other words, while today's batteries are maintenance free, these were not (see photo above). Later in life, when the original battery was replaced with a newer "low maintenance" design, the openings in the ThermoGuard would not clear the low maintenance tops, and were often cut to fit, or discarded all together. 30+ years later, a lot of the 75-77 cars are missing their ThermoGuard all together. An uncut original is quite a junkyard/swap meet find.
