Mini Pentosin (Worklog) 56K Warning

Well guys... while I'm waiting for my parts to arrive I decided to study a little closer the Blue Pentosin coolant since it's going to be the additive I will use. Also I have been requested to post some pictures.

First I ordered the product ($10.82 US) from http://www.car-stuff.com/

Also can be found on any Audi or German auto dealer.

Putting Pento to the test :D Lets see how well will perform for loops with different metal parts at 10% concentration 1(P)/9(W)

I put in the mix: Zinc screw, copper pipe, a dime, a penny, a piece of speaker cable, galbanized roofing screw and a piece of aluminum. I think this will do it :woot:

Well I have seen very ugly metal reactions after 4 or 5 days.. so I thought will be good to get back after 5 days and so on as long my wife allows me to keep my evil experiments :D around the house. Good thing I have no pets.. that stuff is toxic... but I did not notice any smell at all.. in case someone was wondering.

Take a 9V battery and start some action ;)

No destilled water container as control ? Is the aluminum anodized?

Anyway look at the pic from a thread on a german foum Meisterkühler.de, copper pipe and aluminum piece after 2 years and 9 months in G11 (Pentosin) mixture on the left and pure distilled water on the right.

Actually I failed to use distilled water as all I have for now is the Pentosin.. still waiting for all the parts and didn't have chance to get some D Water.. however I thought regular water will accelerate any metal reaction? perhaps I'm wrong with this estatement due to PH? The first intention was just to show the color of the water/pento ratio as I was asked so then I said why not lets just go ahead and do some metal reaction study.

Your picture it's just stunning .. I'm glad I picked the right stuff ;)

I have tried researching on Pentosin and found very little due to language barrier ;)

Wow...Pentosin is that good? I was going to just use some standard anifreeze...

Wow, I'm really impressed. That Pentosin is superb stuff. Have to get some.

http://store.impartsol.com/antifreeze.html

They have red and blue here.

I personally been using a G12+ from BASF for ages, which is also silcate free unlike G11. The G12 (don't mix with G11) and G12+ (G12+ can be mixed with G11) are formulated especially for aluminum engines, so I would think it might be better suited. I know quite a few people which run either G11 or G12 from all kinds of manufacturers in their WC setup and never had a problem, so i assume as long as it meets the standard, the manufacturer is really secondary.

Edit: (G11 can be mixed with G11) replaced with (G12+ can be mixed with G11)

Any way you could get some pictures of the coolant mix being pumped through some tubing? I can't verify that Pentosin is sillicate-free so it might become cloudy in use with Masterkleer tubing.

What about putting a small cut piece of tubing in the mix as well? I would be curious to see if it "Stains" it in anyway.

I don't have the parts with me not even a piece of tubing yet but check this thread... it has some cool pictures with Pentosin in the loop.

I totally agree with you.. I noticed it was formulated for aluminum engine also saw the german link you placed before there was the BASF product picture.. BASF has always made great products as far as I have memory.

Thanks for the link. Pentosin looks nice, that’s for sure. IIRC others reported that Zerex and Water Wetter left a slightly opaque film on their tubing. I have not seen any reports of that with Penstonsin yet.

Not sure how I am going to proceed yet. Optimally straight distilled H20 and a couple drops of dishwashing liquid to kill any "baddies" floating around would be best. I will admit though, the Pentosin is tempting.



edit: spelling!

Get Pentosin. Its expensive, but whatevers its good stuff. You might wanna see if someone is parting some out cause there's no way you can use up 1.5L of the stuff.

Is Fricofin G12+ (from Fuchs) the same as Glysantin?
Because I picked up a 1,5 L bottle in the Bauhaus in Aachen today, for 3.95€.
It has a lila color, like G12+ is.

Glysantin is the brand name of BASF coolants, if you have a G12+ it should be virtually identical to a Glysantin G12+. The purple color indicates it's a G12+, G12 is red-pink, G11 blue.

The automotive Industry in Germany has lots of standards, if it meets the standard I very much doubt there are any major differences and maybe not even minor ones. Products of the same standard have to be interchangeable without ill effects. The basic composition is the same, and the additives are probably too to guarantee compatability.

Just ordered some of the blue stuff, hope it works well.

Thx.
I wasn't that sure about it. At an Esso station, they had some own branded bottles which contain Glysantin Protection Plus (=G11). Just to make sure I had something right to bring back, I bought 1 bottle of that too. Color is blue.

Which one would be better to use now, as I have a CC25 reservoir? G12+ or G11?

Guess depends on what color you like best :P Personally i use G12+, but most people i know use G11 and it works just as good.

Any updates?

booooooooooooooo well I have some comin anyway

<<< Update >>>

It has been a little over 3 weeks and so far all the metals look just like the first day.. no corrosion no stains no problem.

So far so good...

One interesting thing is while I was putting my loop together I left some Pentosin mix leftover on a plastic container on the basement and open.

Yesterday as I was working a little bit on drywalling the basement I saw the container and noticed some contamination floating... so I said what the heck... I first I thought hmm maybe are pieces of wood or drywall dust.. as I grabbed the container.. there were lot of little dead ants floating and some still semi alive.... wow.. first I said .. it has been dry and maybe they just went kamikaze with the water... but the interesting part is right next to that container there was another one with regular distilled water... so what's going here? It seems like Pentosin has something that attracts ants.... and obviously kills them.. I kind of tried to smell the container and it does have a little sweet smell very little I wonder if that's why they are getting attracted.

Also the container was an empty winshield liquid bottle I washed very good.

I'll post some pictures of the amphibious invasion later when I get home

:D

Pentosin: When Ants Attack! :o

ill guess the ants failed to read the warning on the bottle;
Poison-harmful or fatal if swallowed or inhaled.


still nice and blue with "only" 10%. is 10% safe too use, shouldnt affect colling that much?
Is this antifreeze or just coolant additive, guess its not any glycol in it?

its antifreeze, used in german cars. not sure if its glycol-based tho.

apparently its 95% glycol http://www.worldpac.com/msds/WP_088.pdf

ok. now i had to check the colour on the antifreeze i got standing here.(glyco based though)
pictures in 5min.. mine is blueishgreen.

Just looked on the bottle, it contains ethylene glycol and diethylene glycol.

ok that explains the ant thing. it tastes quite sweet. (dont taste to much on it:D )

ok.
first its pure, then 50\50 and then 10% and then 5%. dont need more than 5% for color... :) but i want the rally blue pentosin thing. this is a bit greenish.

Wwll, you should easily be able to find some in Europe...

Yeah, a 3L tank from the audi store maybe... Marci said he's having trouble finding a supplier (i suggested it on the over-clock.co.uk forums)...

Well, basically there are three "colors" of that stuff. Red/pink (Audi/Volkswagen), blue (BMW) and some "general" stuff used for many kinds of cars.
Castrol has some nice pre-mixed coolant which should be sufficient when used in a typical additive amount :) Has just the same color as the stuff above.

bmw you say... ill go look there.

Yes. Used to work at a BMW dealership, we always used that stuff... I'll try to get a picture of the Castrol stuff tomorrow, especially its "ingredients" :) Castrol is a official BMW supplier here, so maybe it's just that stuff you can get there, just not pre-mixed.

Hei hei eXa :)

I bought mine anti freeze at statoil( :p: ), and it's just as blue as the pentosin. Yours however, eXa, is green! The dealer said the one I bought was for audi and vw, but then again, she was blond :D

The Pentosin that I bought was also for VW/Audi and it is blue.

ok thanks ill sheck out statoil. the one i got is shell:stick:

LMAO..!

Well here it is:

It really looks like pieces of wood but are 100% Pento-Ants :D

One more to go...

http://img125.imageshack.us/img125/8...ttleanttj8.jpg

we call them sugar ants here, you can gues why lol.

I found some pentosin at a local auto parts store that specializes in inport parts.

Before ordering online, you may want to check your local yellow pages. I'm saving about $5 in shipping and that is with tax figured in.

This stuff is great! It does not foam at all which cut my bleeding time in half. Looks great too!

Well guys finally got the Pentosin G12 demo from Petras along with some 7/16 Masterkleer tubing :banana:

Thanks Alex..!

http://img96.imageshack.us/img96/2174/g12samplews6.jpg

To be honest we should not call it Red Pentosin... instead we should call it Pink Pentosin... Hey ..! Still looks cool.. I'm sure your girl will love it :D

Regarding the UV reactive part.. I don't really have anything yet to make it work.. but I placed the tubing demos on the direct sun..... so you can get the idea ;)

Thanks Petras.. for your interest on Water Cooling Research :toast:
http://img91.imageshack.us/img91/1782/g12finalfy3.jpg

PinK.SkY will be all into that stuff.

I hear there's 2 different versions of G12 one pink and on reddish? I think Radical mentioned something along those lines...

mmm...kooollaid....i mean pentosin!

did you try mixing it with the blue yet? :cool:

You shouldn't mix G11 with G12....

Anyways, that's an erm...manly colour ;)

mmmmm, pink pentosin. Mixing with blue :D purple pentosin!! hahah.

Do not mix G12 with G11 unless it's G12+ (at least not if you wanna use it in a WC).

G12+ should be purple, but this one looks very similiar to the G12 pink.

Anyway here's some G30/G12+ BASF Alu Protect Premium for comparison (although without proper calibration these image colors are not really accurate).

http://www.honigtopf.mynetcologne.de/G30-G12+pic1.JPG
http://www.honigtopf.mynetcologne.de/G30-G12+pic2.JPG

I have just got some of the G12 to use myself.

I would like it quite a deep colour but, the bottle says to mix it 1:9 which from the pinks above looks rly weak. Can I just mix it in a more concentrate solution or will this cause me problems??

r4z

Not a good idea, considering its basically pure Ethylene Glycol + Dye.

Yes, 1:9 Really does looks weak.... in the tubing.

1:3 Was the best look IMO. But not sure how bad it will be in a loop at that concentration. :eek:

Since I'm more of a performance-oriented person, I put 1:9 (10%) on all of the bottles (even though that can be considered too high) and noted on the website that you can use more to enhance the color, if desired. The only thing it'll hurt are your temps :rolleyes:

BTW, I added a UV shot to the website but the color is just a tiny bit off (it becomes more of a red-orange under UV light at 100%).

http://us.st11.yimg.com/us.st.yimg.c..._1910_40182038

Darn, its a little too pink for me. Too bad you cant get a nice solid red without clogging the jets of your waterblock or killing performance.

Looks nice and red-orange under UV. Anyway pink is very fitting for all you bling-obssessed pansies imo =p

@creidiki,

I picked up some "Dowfrost" propylene glycol which is designed for HVAC cooling systems. It is silicate free and is designed to enhance heat transfer not impede it. Also it is colorless so now bling!

G12 (+) is silicate free as well. Propylene gylcol has higher viscosity and less thermal capacity, main advantage is it's less toxic in oral intake. Anyway both should perform very similiar, especially at 10% solution.

I know, I want Dowtherm 4000 but have not found it yet. I run about 1-3% in my loop.

@Fairydust,

Sir are you a chemist?

I've heard that before. Good reason for taking G12(+) over G11 imo... I dont give a toss about the white film on tubing from silicates, but clogging is always a concern with (semi)impingment blocks.

is it smell bad like WW? I need to find a friend with Audi Car :)

is there a blue g12+?

just the g11 one..http://www.petrastechshop.com/peg11coadb.html

That's what I'm going to run in my first loop. Looks like koolaid huh? :)

Quote:

---

Exceeding 85% will cause the silicates to drop out of suspension and goo up to clog the radiator and reduce heat transfer.

---

I think we're okay with the whole clogging issue :/

How's the corrosion going? :p:

If you wouldn't be satisfied with the blueish at 1P/9W what would be the best think to add to give that extra blue a kick? Even though I know that UV dyes generally are not recommended. Is there anything you could add that won't hurt performance to give some extra blue color?
Here's an example of the shade i'd like.

The coolant in that loop is Gigabytes coolant that comes with the Gigabyte 3d Galaxy kit.
Nice color I say :)
