Coolant overdose?

Gdat Axle,

Im with you.......it was just a quick fix until the next service...........Im a lazzy bugger and leave it to the mechanic.

Cheers

"some cheap and nasty" , the 500ml concentrate I have cost $14.10 and will treat 10lt , the same brand premixed in a 10lt bottle costs $48.95 retail , which is a rip-off ? Which is the cheap and nasty ? Methinks it would pay to read the specs required for the vehicle and then read the specs of the concentrate and the premix prior to making an INFORMED decision.

my point is 500ml of concentrate WILL NOT treat 10l. No reputable brand will claim that it will - only nasty stuff like tectaloy etc .

if it really is concentrate it will contain around 930ml/litre ethelene glycol

now ethlene glycol needs to be added at the rate of 33% MINIMUM and ideally 50%


so you would actually have to have 10 bottles of your concentrate to do the job which will cost you over $150 by the time you add it to distilled water

now go back to the shop and look at that 10L bottle - does it even tell you the amount of ethlene glycol it contains? if it does does it work out to 33-50%
- im GARANTEEING it doesnt

cheap n nasty brands will often advertise you only need enough to colour the water because properly mixing coolant is not cheap and a $15 bottle will satisfy those without a clue looking for a cheap way out.

While you are back in the auto shop - pick up a proper name brand of concentrate like castrol, valvoline etc. Observe on it how much EG it contains. (Will be over 900ml/l) then read the mixing instructions on the back
- You wont see any 500ml does 10l on that stuff.

Properly filling your cooling system aint cheap. i should know - been doing it for years

As I said , READ the specifications , For a Holden rodeo = Specification # Hn2217 ,part #92141458 = 1lt concentrate or part#92141457= 20lt premixed ... both manufactured and sourced from DeVille Australia Pty Ltd SA., Maker of ???? oh no !!!! Tectaloy.

ok so thats 5% ethylene glycol

thats not going to do much

you can read anything you like on coolant addatives and you will never find anything recomending less than 33%concentration

here ya go heres the penrite coolant that conforms to holden HN2217 specs

recomends concentrations of ................ %33 at a minimum which only raises the boiling point to 104 deg

if you use 50% it gos to 109 deg

5% like your advioocating wont do a thing

sorry link

HN 2217

and again heres wynns coolant conforming to that spec

surprise surprise

recomends using at 30% min to 50%

you will never find any thing different recomended

I use the lolly water sold by tectaloy .... Never had a problem with it ... but then my coolant maintenance doesnt happen once every 10yrs either.

Doesnt mean its the best of course ... nor am I recommending it.

Personally, I think the only good thing about the additive is the lubricating qualities.

IMHO the fact that the additive ... and high pressure caps ... are used - is simply to allow manufacturer shortcuts ... in regard to smaller and inneffective radiator/fan systems.

We would probably be better off with water ... a decent radiator ... and a lower pressure cap - rather than having a fake coolant temp of 100'C suddenly leap to its real temp of 120'C or whatever, at the first sign of a cooling system issiue.

"100 percent ethylene-glycol freezes at 22 deg. C"

see below

Pure ethylene glycol freezes at about -12 °C, but when intermixed with water molecules, neither can readily form a solid crystal structure, and therefore the freezing point of the mixture is depressed significantly. The minimum freezing point is observed when the ethylene glycol percent in water is about 70%, as shown below. This is the reason pure ethylene glycol is not used as an antifreeze--water is a necessary component as well.

All the wording in the dittos was straight from a service manual .....

There is a reference in one or the other about "freezing" as in solid ... and "freezing" as in a 7-11 shop, slushy drink state .... both rather catastropic for an engine apparently.


Its all coconuts and acorns to me .... I either run straight water out of nescessity after patching a leak ..... or 50/50 coz the anti-freeze has the lubricants and stuff the waterpump and alloys needs.

In addition, 100 percent ethylene-glycol freezes at 22 deg. C (-8 deg. F ) ...."

Shouldn't that be 22 deg F (-8 deg C)?
(Actually 22 deg F is closer to -6 deg C)

Dunno ... a typo in manual during conversion ?

It was the first paragraph I was offering as the most informative ... as freezing is rarely an issue an Aust veh has to deal with anyway compared to canada or somewhere.

Temperatures of anything are variable due to ambients & locations ... so I was more interested in the buildup of grunge from 100% eth-glycol than anything else.

Hairy,
don't worry about the coolant, just make sure you got your stack hat on during the driving lesson.

What sorta coolant has it, is it the red tojo stuff.

Have a good one.

Hi Bucky. Mixed coolant brands going to gell not an old wives tale, Have personaly removed 2 different radiators from Ford Couriers that customers toped up with different type of coolant it Gelled & blocked rad core 75% % had to be removed dismantled & cleaned out. Over 50% ethylene glycol will start seeping through joints. Cheers Daryl

Agree with dbish.

if you mix different types of coolants, you will get a reaction between the two, and it gells like thick snot, blocks up the tubes, tank/ heater core.

Not good.
Used to work next to a radiator business, saw it so often, along with damaged motors. Very sad, as it didnt have to happen.

I would recomend genuine toyota coolant, or motorcraft R13b in the 500ml bottle.
Both are good products.

I will never use tectalloy lolly water ever again, either premix or the concentrate.

Flush rad core, heater core, block, and drain.

Use new filtered water, or demineralised water if you use a concentrate.

Used the motorcraft coolant for many years, have seen one EA falcon that did 150k on its original head gasket whilst using the motorcraft product.
All the other EA's I saw came in at 70 to 80k with leaking heads.
