Red coolant for 2M?

[deluxoglide]

I have heard some exploding type stories about green coolant in 7m.

Does anyone know if this extends to other m series motors or am i involving myself in another 7m specific problem unnecessarily?

The Toyota "red" coolant is good stuff. Any "M" series engine would benefit being filled with it.

CAUTION: You must completely flush the radiator, the engine and the heater core of any other coolant. You can not mix the different types, they coagulate and totally gunk up the cooling system.

Replace all your colant hoses, especially the bypass one under the intake manifold. This little sucker is often missed by mechanics, and backyarders alike. This is the one that lets go and instantly blows your headgasket!

so did they fuck up when they created the green coolant or is it merely the combo of both red and green that see's these problems occur?

[matty87]

As far as i know it is merely the combining of the two. The two chemicals are different but they are designed to do the same job but like is said above they dont go together well and thats when the problems are caused.

[deluxoglide]

thankyou all.

i shall flush the green poo wipe my hoses and fill with the red stuff

On the topic, Is the Red stuff recomended for all toyota engines.
Should i be using it on my 4AGTE?

thanks

its really best not to mix any different brand together,allways a complete flush before installing new coolant.

Toy long life is awsome stuff,i would recommend sticking it in anything.

Definately a smart move.

yeah red, green and pink coolants shouldnt be mixed
green is the old 12 month stuff
red is toyotas 2 year stuff
and pink is the 5 year super long life stuff, sold premixed.

red and green will suit the older toyota engines, newer ones use the newer coolants
BUT! do not rush out and put the pink stuff in your 300k 20 year old engine.... the stuff is very good at corrosion resistance, so it will clean up a lot of deposits through out the engine, which means it could cause leaks in an old worn out engine.

green coolant will not cause a 7M to die the issues about them are well documented, simply putting in red or pink coolant will not fix them

so imo if you have an old worn out high kay engine, run the green stuff, if you have a good engine or rebuilt use the red. if you have a brand new toyota use the pink if specified

[schnitzel]

Green is actually 3 year stuff and red is 5. Always pays to buy the better stuff and mix it yourself. The premixed are often only 33% active constituent where you really need 50%. depends on your local tap water wheteher you can use that or need to get distilled.

Red and Green DO NOT mix and merely flushing is not always enaugh, There are at least 3 other types of coolant out their for specific vehicle types and then you get into Diesels which are different again. Toyota coolant for example is not recommended for Volvo, ford or Holden.

I was under the impression that the Red gear was specially formulated for alloy headed vehicles, where as the green coolant did not have that in mind when they designed it. Either way, Toyota Red is what I will be using for my 18R-GTE (whole new system, except heater core, which will be heavily flushed and pressure tested)

See following straight from the castrol website except for bits in brackets


Castrol Anti-Freeze Anti-Boil (green stuff)
A general purpose ethylene glycol based coolant with corrosion inhibitors to protect aluminium alloy, copper and cast iron engine components.

Castrol Anti-Freeze 350
An ethylene glycol based coolant specially formulated for Holden (eg. V6 Commodore) corrosion and water pump seal performance.

Castrol Antifreeze SF-O (red stuff)
A concentrate long life engine coolant based on neutralized organic acid technology (OAT). Provides outstanding corrosion protection and cooling performance in engines employing cast iron and/or aluminium and also with aluminium alloys.


Green stuff is Glycol based, red is Organic acid, is really down to personal preference. Neither green or red are specific for Alloy, however neither is suitable for american diesels. Note however commonwhores need there own stuff. On a similar vein toyota are still the only manufacturer specifying Dot 3 brake fluid everyone else has moved on to dot 4 and dot 4.2 so sometimes Toyota can drag the chain on change. ( toyota's argument centres on seal material in Master cylinder and compatibility problems).

Back on topic however too high a concentration of either red or green coolants can in fact be as bad as not enough so make sure you mix it manufacturers specs.

[Mr Revhead]

green is the old generic 12 month stuff...... from the days you used to change it every year
red is toyota long life, 2 years and pink super long life 5years. the later comes in a premix only. unless toyota aussie do it differently from japan and nz

And I've seen the toyota llc and sllc mixed a few times by dealers doing coolent flushes on cars made around 2003 when the sllc came out . Doesnt seem to cause any trouble mixed at this stage , I would never do it tho .

SLLC is 5 years till first change, and then it's meant to be 2 years from then. And yes, premixed 50:50 in 1L and 5L bottles.

I use LLC in everything, cos I get it free from work. My MS65 4M had it and never had any problems. And definitely replace that bandit hose under the manifold. Mine was ready to let loose.

LLC and SLLC can be mixed no worries. Before every Toyota had SLLC from factory, there were heaps that weren't labelled that had it in it. The service schedule still has 24 month coolant changes in it, so you do it and put LLC in it.

RE Commode coolant, for the older ones ie the green shit. When on a Tectaloy factory tour the guy said it is the worst coolant they make and the only reason they make it is because people buy it.
