It says safe for aluminum engines.

Doesn't say one way or the other about silicates.

Is there a way to determine if it's silicate free?

The only things listed are Ethylene Glycol, Diethylene Glycol,
Sodium 2-Ethyl Hexanoate, Sodium Neodecanoate & water.

The nearest store is not close by.
I still have to take the bike back apart to see why the kickstarter
I added locked up at first (see other thread), in the meantime,
I'd like to know if I am going to hafta go to the autozone or schucks
after I get it back together.

(The motorcycle places are closed on Sunday)

Living in the country has drawbacks, like distance from stores,
and specialty stores closed on Sundays.

I can't tell you about the Antifreeze. I have seen answers both ways. What I can say is my Ford uses the old type coolant and it says not to use the long life coolant. Motorcycle cooling systems are basically the same as cars, so I'm following that line of thought. I don't have any vehicles that use the extended life coolant so I stay with the old coolant in them all.

Probably makes no difference but that's the way I'm going.

Napa should sell Engine Ice. That will work.

I want to use what I have.

My understanding is that the Extended Life NAPA is good stuff.
(NAPA Extended Life Antifreeze/Coolant is what it's called on the container,
I couldn't find a part number)

I know it's recommended for the Ford Powerstroke 7.3L
(which is why I have it).

It's about 1/2 hour each way to the nearest store.
I think the NAPA may not be open Sunday.
And the way my weekend is going, I would get to Schucks or Autozone
and they won't have anything that says whether or not it contains

So I think I'll just go with the NAPA Extended Life Antifreeze/Coolant
for now, and see if I can get a definitive answer on whether it contains
silicates or not.

As far as I have ever been able to tell the "phosphate free" and "silicate free" claims are just advertising gimmicks. Just because one says free and the other doesn't, does not mean there is any difference in the 2. I would not worry about that. Your Ford diesel has the same design water pump seal as the DRZ. I use standard Ford coolant in everything.

Could be, but just like "Caffeine Free", it's good to see it spelled out
when it's important to me.

I ended up getting a gallon of Prestone 50/50 premix Extended Life
at Walmart because it said Silicate & Phosphate free specifically.

Bleeding the cooling system is a bit of a PITA.

But that's nothing compared to the kickstart install troubles I had.

Out here distilled water with Water Wetter works great. Doesn't get much colder than the low 40s though.

That must be nice. It was colder than that here just this morning. 33 Degrees to be exact. In October. I can't wait until winter gets here. :bonk:
