Toyota Red Coolant

[1200det]

A few Things on my mind on a Tuesday afternoon :

Why isnt the Toyota Pink Coolant on the POLL ( Toyotas Extra Long life 150,000km life )

How could one say there green coolant has treated them fine but they dont know how much against corrosion ? In what way has it treated you fine.

1. As an Anti-Freeze ??
2. As a anti - corrosion additive ??

3. Against my car boiling ? Although its called coolant it actually reduces the boiling point of water not raises it so it should never be reffered to as a coolant by any means.

You mean it raises the boiling point and lowers the freezing point...Thought so

NO

A 50/50 Mix of Water and typical glycol anti-freeze/coolant WILL BOIL at a lower temperature then 100% Water.

theres an article about this in the last hot4's
the difference between the red and green coolants is reds use an organic acid as the corrosion inhibitor whereas the greens use silicates, phosphates and borates

the acid has a much longer lifespan and is good if your too lazy to change it every 2 years
apparently its good for upto 5 years or over 100,000kms

doesnt mention anything about them cooling any better, but i think they all use ethyl glycol as the anti freeze/anti boil

Are you talking shit coolant or decent stuff. I was referring to decent stuff

Hi,

A few Things on my mind on a Tuesday afternoon :

Why isnt the Toyota Pink Coolant on the POLL ( Toyotas Extra Long life 150,000km life )
Dunno - never used it. As my radiator gets flushed annually the requirement for a "long-life 150000km" product doesn't interest me.

How could one say there green coolant has treated them fine but they dont know how much against corrosion ? In what way has it treated you fine.

1. As an Anti-Freeze ??
The car is always garaged and it doesn't get that cold in Sydney to require anti-freeze. So, I'm not fussed with anti-freeze capabilities.

2. As a anti - corrosion additive ??
Yes. To keep the radiator and water channels clean and free from rust and/or debri. I check the run-off in the container to make sure there's no sediment or other debri. The system is flushed out with clean tap water. Then filled up with tap water and additive. So far the run-off has been clean and no sediment etc. Based upon this and the fact the engine has ran at the same temperature as when it was new (the engine is now 33 years old), I figure everything is okay.

3. Against my car boiling ? Although its called coolant it actually reduces the boiling point of water not raises it so it should never be reffered to as a coolant by any means.
My engine runs at just a fraction below 80C. On the hottest days with the A/C on it can go a whisker over 80C. In an emergency I ran it on coke and OJ and it stayed at 80C. So, the ability to reduce the BP of water isn't a capability I am interested in.

I found this little article on this topic:

how do you come up with that conclusion? an undiluted coolant will boil at a much higher temp than plain water....
sure the cap does its job too, but even so, the coolant raises the boiling point

Im in Canberra so i need the anti-freeze capabilities otherwise there would be noway i would use coolant/glycol, I would run with straight water and Toyota anti corrosive/rust additive or straight water and a surfice tension breaker and actually reduce the running temps of water.

Coolant DOES NOT raise the boiling point of water.


A few tests done from Royal Purple :


For example, the average operating temperature of a 350 c.i.d. V8 engine (equipped with 160° thermostat) when dyno-tested with different coolants are:

A.
Standard mix of water and glycol (antifreeze)
228° F

B.
50 / 50 water / glycol mix with Purple Ice™ added
222° F

C.
Straight water (no corrosion protection)
220° F

D.
Water with Purple Ice™ added
200° F

Your graph proves it. It says normal water in the middle which is i assume 100degC, with royal purple below it - Maybe its shit coolant. Then theres antifreeze (which is coolant anyways) displayes with a higher boiling point.

Coolant DOES NOT raise the boiling point of water.

I guess you win on a technicality. Coolant won't raise the boiling temp of water - Nothing will as it will always be 100degC. However, by adding antifreeze/coolant, the resulting mix wont boil till over 100degC.

Why they or we call it coolant i have no idea LOL its should all be called anti-freeze.

Either way Glycol additive/s raises the running temperature of the water in the combustion engine.

Hi,

212F is the temp for normal water to boil (100C).

You can add salt to raise the BP of water. That's why some cooks add salt to water when they boil pasta and eggs. Though salt is not what you would want in your cooling system in your car.

Water/glycol mix was used in liquid-cooled engines during WW2 to raise the temperature of the liquid-mixture above the boiling point of straight water.

ok - threads like this in the tech and conversions section are WAY too broad, and simply open up a platform for people to chime in with "i think, i heard, i use, i blah blah"...

... threads such as this generate and perpetuate misinformation. i am locking this thread, and suggest the author, or others restart a new thread(s) with a specific question such as 'why is red coolant better' or perhaps 'thermal properties of coolant mixes' or even say 'the engine as a battery - why is my head corroding'
