Non Dexcool Coolant

I haven't seen Final charge at Walmart, just the usual Peak and Prestone and ST dexclones. Now I'm starting to think Final Charge is the better one. Pep Boys carries it but I'm not sure on price.
 
Hmm I guess Napa doesn't carry Peak Global maybe? I think they are the source for G-05 and I like Zerex. I don't think G-05 is the best but I'm starting to sort of favor it over PGL even though it ahs silicates just because I think it's more proven. If Zerex would offer the P-OAT in concentrate I'd go with that. I don't know why they don't do that.

Actually if I'm using a coolant exchanger or can drain the block drains I'd probably go with one of the pre-mix P-OATs (Zerex or Japanese OEM) despite the little extra cost because I think it's a better universal choice than G-05. I believe draining the block will get 90%+ of the old coolant out and get you about s close to 50/50 as putting in half the listed capacity and topping with water.
 
I bought Peak Global at my local NAPA last year.

Seems like everyone else just stocks generic Dex clones - usually Prestone and their own house brand.

No. I visited my local Napa store and called one a little further away. The one closest said, they don't carry it, and that "most customers want Prestone." lol

I don't really need to do a flush right now, just when I visit an auto parts store I check it out. I'm just going to be interested to see how the Peak GL, Peak PPL(@PB) shakes out. It's still on Peak's website but seems to be getting more and more scarce. Though I'm not afraid of using the universals in my Asians with regular maintenance, I would prefer to give PGL a go in at my vehicle(s) next time.

That said, all Peak now advertises is the Long Life with Danica.
 
Zerex original green is fine for older cars. It works great in all iron engines actually as long as you change it about every 2 years or so. It works OK with aluminum but probably not as good as the others. G-05 would be another good choice for classic cars.
 
Did you guys ever research into Pencool 3000 antifreeze stabilizer. I can vouch for this stuff. I had a 1994 Dodge and I used this stuff and never changed the antifreeze just maintained with the Pencool and after 12 years the outside rotted in, I cut the radiator open and it was like new inside, no water pump trouble nothing. I use it in my 2006 Dodge with the Hoat, since its the same antifreeze Cummins specs and that is originally what the Pencool was designed for(big trucks). It seems to work in old school green very well. Ill swear by it, you can over dose it and have to maintain it with test strips, but for a car sized radiator, a pint lasts 5 years or more. You can get it at Big rig dealerships or Cummins, Cat or Detriot dealers.

Around where I am, Napa is your best bet for coolant. They carry the entire Zerex line.


NAPA is, IMO, the best national parts store for lots of reasons. Price NOT being among those, unfortunately. I almost always use them for mechanical parts. But they can't beat the convenience of a CarQuest and PepBoys, both walking distance from my house, so I shop there for fluids often. CarQuest has much, not all, of the Zerex line on the shelves.

Pep Boys in my area just continues to go downhill. They used to have a big coolant section with Prestone, Peak, and Zerex lines in addition to their house lines. Now they're down to a Prestone shop with a FEW Peak products. In the Peak line, they don't even have Global or Final Charge. Just LongLife. In Prestone they have the true DexCool and then "No Makes No Models" universal ethyl hexanoate [censored], plus their own "No Makes, No Models" bottled by Old World (probably about the same as Peak LL). So around here you can't get a truly correct coolant for your car at Pep Boys unless you drive a GM or something else that specs DexCool.
 
I did see Peak Final Charge at Pep Boys. I don't know if they have it at your Pep Boys or not. I think NAPA use to be a lot better amd is still good on coolant choices (with good prices) and they sell good belts, hoses and OK filters (not so great prices), and they have a lot of obscure speciality tools and parts.

But I have to say outside of that the general quality of their parts and speciality tools has gone way down hill. About all their parts and tools are made in China and they sort of try to hide that fact. I think I might've recently got the last of the USA made tire pressure guages there. I have bought speciality tools form there and they kept breaking and never worked and I had to get the tool somewhere else. That's not to say all their speciality tools are junk but they're all made in China along with most of their auto parts.

A lot of times I find a better part sometimes made in USA at AA, AZ, or maybe O'reilly's. I don't shop at Pep Boys much because there's not very many convienently located to me and they have nothing much to offer over AA and AZ. Carquest is not very big here and seems to have fewer stores now than they use to.

Well, that's true across the entire parts industry. The "Chinese made" bit is ABSOLUTELY true for tools, but not so much for parts (heading that way fast, though). You do have to be careful anywhere you shop. I've found NAPA to have more US-made and North American-made PARTS (not tools) in general than the others, which is why I still rank them high. O'Reilly is pretty darn good too.

Because of their prices, I generally don't use NAPA much for consumables (fluids, filters, etc.) and try to snag those kinds of things at other places. But I ALWAYS read labels: I was looking at the rack of wiper blades in some place the other day. Anco blades were Hecho en Mexico, the Rain-X stuff was Korea (or Malaysia, I forget which) and the generic brand was all made in China.
 
Yeah, I think Napa actually is pretty reasonable on coolant prices. Plus that have the ful range of choice and Zerex, the good stuff.

I don't know much about Pencool or the heavy duty antifreeze so maybe someone else can chime in, but I thought Cummins was using a dexclone? Pencool sounds like something different from Dexcool but I don't know much about it.

Prestone has a Heavy Duty coolant that meantion it's Pencool. I haven't seen it anywhere though.

I think you might be on to something with this Pencool. I was just looking at Penray's, makers of Pencool, website, and they have a boatload of coolantr information. They have some technical bulletins and it mentions how OAT's gave HD engines problems. It goes on to say that dexcool wasn't compatible with traditional coolant. Although some of this info is kind of old.

I'm not sure what Pencool can do for a passanger car above G-05, and I'm not sure how you can add the inhibitor to anti-freeze that already has inhibitors and the compatibility issues. Anyway Penray's site ahs a ton of info:

I did some reading on Pencool, and it appears it is an IAT that uses silicates and nitrites but no phosphates. They recommend to use a fully-formulated IAT coolant such as FleetGuard, then after so many miles test the coolants nitrite level with test strips and add the Pencool 3000 inhibitor as needed.

They don't recommend using it in just any fully formulated coolant but it probably would work OK. I think the formula is vary similar to G-05 having silicates and nitrites, but lacks the OAT the G-05 has. I don't think OAT is a bad thing just that the OAT 2EHA is known to sometimes cause problems.

I think I will just stick with either G-05 or Peak Global as a substitute for Dexcool or other OEM automotive coolants.
