Red seems to leak easier, yes.

Another question or maybe opinion. Does the red tend to leak more than green. Seems coolant leaks are more common now than before. Or is it just that the systems now are more complex and so many more places to leak. We are always chasing coolant leaks on diesel engines now.

This has been a very informative thread. I have tried to stay informed on coolant but like a lot of things as you learn it gets even more confusing. These new coolants claim to be more environment friendly but when you read the label they are all still ethylene glycol based so kind of confused on that.

Steve is right. Drain and refill with water. May be a good time to add some cleaner too. There are all sorts out there. Add some and fill with water. run and drain. Then go with whatever colour you choose.

You best drain every where possible and refill with water and drain again. You won't like the results of pink and green together. In other words,it needs totally flushed.

Am looking at draining and replacing the coolant in my 175 . Going to go with the heavy duty pink antifreeze. Assuming that this would not matter with having an external circulating block heater but just wanted to get your opinions. Do you usually just drain at the radiator? Need to look in the book to see how many gallons I will need.

In my days as a Ford tech, we got most of Ziegler Caterpillar’s 6.0 powered trucks. They started using their ELC coolant and I noticed they had almost no oil cooler and EGR cooler problems afterwards.

Creston, I'm with you on that analysis. Green=more maintenance and Red = Less. Like I said in my post if you don't need the filter with conditioner get a suitable substitute without chemicals. Nothing wrong with clean products and keeping them clean.

Please correct me if I’m wrong to make sure I’m understanding this.
All the Allis diesels I’ve been around (433, 649, 670) have had green antifreeze and coolant conditioner filters. Book says change antifreeze every 2 years, coolant conditioner filter every 600 hrs.
My understanding was back then the green antifreeze was all they had.
So if a person drained the antifreeze and switched to a more modern red heavy duty diesel antifreeze with the conditioner already mixed in it, one would not need the filter?
But if one continues to use the green antifreeze then one should change the coolant and filter at the book suggested intervals?
Thanks

Deere has just made it more confusing by not having the same color of coolant. Oh well.

the JD web site says it is a COMPLETE system and does not need addatives or filter..Says it is a 6 year USE mix.
Im sure JD does not make antifreeze... They have a contract with others.. Just tell them to leave out the RED DYE in the JD batch.

John Deere Cool Guard II says it prevents corrosion, cavitation, rusting, and scaling
When I walk in it's there in the stack of oils and fluids and it's what they grab when we ask for anti freeze or what the mechanics bring to the fields. Comes in 2.5 gallon premixed jugs and goes in everything from the 3020 to mid 2000's year because that's the newest we have. I don't think it's the same as NAPA green stuff that says for automobile and light trucks.
I'd guess it's similar to the Case IH antifreeze. I've notices Case IH hyd oil has a reddish tint to it which makes me wonder if they like to add red dye or something, while JD hyd oil and antifreeze looks more "normal"

I use Chevron Delo ELC in everything. If I do any repair gas diesel or anything it's Delo. If it has a filter I change them. I actually just changed the heater core on my truck and added a filter. Not all filters are the same, some have chemicals some don't. My truck runs a non chemical filter I want the 25 micron filtration to prevent another plugged core. Any Ram owner knows what I'm talking about.

I know this is long but there is a lot of good information in this article. At least be sure to read "HOW DO SCA'S PREVENT LINER PITTING"?
According to the information supplied
by the leading heavy-duty engine
manufacturers, 40% of all premature
engine failures can be traced to some
deficiency in the cooling system.
Neglecting maintenance can be costly.
Engine Coolant performs a number of
important functions:
■ Removes heat
■ Lubricates components (such
as water pumps)
■ Provides freeze protection
■ Prevents scale/sludge formation
■ Protects against corrosion
The first three functions can be
accomplished by using a lowsilicate antifreeze and water
mixture which is commonly
referred to as coolant. Additional
chemicals must be introduced to
the system to prevent scale and
sludge formation and to provide
corrosion protection. To achieve
these functions, supplemental
coolant additives must be added
to the system either as a liquid or
as a dissolving solid contained in
the coolant filter.
Supplemental Coolant Additives
(SCAs) typically contain inhibitors
designed to prevent generalized
corrosion as well as cavitation
erosion, polymers that keep hard
water scale from depositing on
engine surfaces and buffers to
reduce the acidity of the coolant.
When used according to
manufacturers’ recommendations,
most SCAs are beneficial.
HOW DO SCAs
PREVENT LINER PITTING?
Cylinder liner perforation is a
common cause of premature
failure in unprotected engines.
Liner pitting occurs as collapsing
air bubbles in the coolant scour
away at the unprotected outer
surface of the liner. Estimates
show that these imploding bubbles
can generate pressures in excess
of 60,000 PSI at the surface of the
liner wall. If left unchecked,
complete perforation of the liner is
likely. Technically, this scouring process is
known as cavitation erosion. While it
can appear anywhere on the cylinder
liner, most pitting occurs as a narrow
vertical band, perpendicular to the
axis of the crankshaft. A secondary
band may be found on the opposite
side of the liner.
The air bubbles are primarily the result
of vibration of the liner wall as the piston
travels up and down in the cylinder
bore. Therefore, any change in the
design of the engine which increases
the vibration of the liner (such as thinner
cylinder walls, longer sleeves or poor
mechanical fit) will increase the
potential for liner perforation.
To combat the effect of cavitation
erosion, all heavy-duty engine
manufacturers recommend the use of
SCAs. The SCAs coat the liner walls
with a hard oxide film that acts as a
barrier between the liner wall and the
collapsing air bubbles, but does not
significantly impede heat transfer.
While the SCAs cannot prevent the
formation or collapse of the bubbles,
the oxide film is thick enough to keep
the bubbles away from the liner
surface, thus effectively preventing
pitting of the liners.

That's nice, dave. John Deere has gasoline tractors too. So, what is this coolant designed for ??? Diesel engines with coolant filters on them?? Heavy Duty turbo diesel engines without coolant filters ??

You can buy the red heavy duty diesel coolant in concentrate and add 50% distilled water. Since it's sold for that purpose,I assume it's treated accordingly. I could go out and read the bottle.

And one more thing.....If you use this treated modern antifreeze, do NOT use a water filter!! The two things don't get along !! If you have a water filter, shut off the valves.
If there is a heavy duty diesel coolant out there that prevents cavitation erosion of wet sleeves and it isn't reddish/pinkish in color, I don't know about it. There could be, but I prefer to stick with what I absolutely know works.

One of the reasons this site is so nice. Even just daily reading through the posts is enough to teach people a few things that might help them learn something the dealer may not tell them or warn them about.

Dr Allis, about 4 years back my AGCO dealer gave me straight green anti freeze for my brother's 7030. I assumed it was treated ...... at least I hope it was. I told them it was for the 7030 and I paid a healthy price for it.

Got to be careful what we're talking about here. For diesel farm tractors, you want heavy duty diesel engine coolant which is reddish pink in color !! Not any other color and not for automotive...HEAVY DUTY DIESEL ENGINE use. If you can buy it straight and use distilled water to dilute, then that is fine.

So no straight A/F is equipped with the additives in the jug that will be mixed with distilled water ? Just curios

I buy straight antifreeze, then mix with distilled water. Have done that way for decades. Distilled water cost maybe a $1.25 a gallon. If you do the math, it’s cheaper to buy pure antifreeze, and distilled water.

I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

When using the good premixed coolant without a filter, Should you add more additive or drain at certain intervals? My 185 only sees about 20 hours a year. I don't want to drain and replace every year if it isn't necessary.
