HT-9350 is showing for the YM 336. And is one of the 160 Deg. Thermostat also. This is what I use, they have it premixed 50/50 also.

Distilled water is steam vapor collected on a stainless hood into a stainless or glass basin.

DI water is De-Ionized. You can look up the process.

RO is Reverse Osmosis, going thru 2 times.

The three shown are the ones out there for ALL VEHICLES, FOR ALL MAKES AND MODELS. Meaning they are acceptable even of the old classics. These formulas are safer to use in the old systems, like your El Camino.

To flush out WELL TAP WATER, you will need to also use C-L-R. Well water is known to contain all kinds of things. My place runs both a sediment filter and then a 2-micron filter before the holding pressure tank. It's not quite RO.

As for preference, there is only one on the shelves in all the box stores, the Prestone. It in Walmart, Menards, AutoZone, etc.

The trouble maker coolants are the ones with For GM vehicles only or DexCool type formula. In fact the original GM DexCool formula had several Class Action Lawsuits for making sludge and destroying engines. GM with other woes then did a bankruptcy. The court then agreed with GM and gave a $500 voucher towards a purchase of a new GM vehicle as restitution. For the 17-million vehicle owners in the Class Action Lawsuit, it was the last day they would ever own another GM product. In fact, the boycott was very strong for a few years even after that. Only the 2nd US gov bailout saved them. Out of the 17-million owners, many were their own UAW and engineering employees. Entire generations of GM families walked away, swearing never to own their products ever again.

The original GM DexCool was also used in a few other selected vehicle brands outside GM too.

bmaverick, Thank you for the detailed explanation and the clarification of the 3 pictured bottles. The advice of the CLR usage when flushing is also appreciated! I have the Prestone fluid on hand. I also have my well water to the house reverse osmosis & filtered, but I'll just go buy some distilled to be safest. I appreciate hearing "the rest of the story"! Greg

DI is deionized water and RO is reverse osmosis. I use distilled myself, readily available at any supermarket.

Both my Kubota's take ordinary green antifreeze and so does my diesel pickup truck. My focus takes long life and my wife's Burb takes Dexcool.

DI water is what they use +Urea in diesel exhaust fluid.

Thank you for the detailed descriptions 5030. Appreciate the knowledge.

You might want to order a new radiator cap as well. After a time, rad caps loose their spring tension and won't hold any pressure and pressure is important because it raises the boiling point of the antifreeze.

Appreciate the thought but I have a cap tester and mine is ok. But I'll consider changing it when I flush since a new cap is small $.

The 240 manaul clearly states use antifreeze At 40% soft water. What is the difference in type from back then ?. I use Diesel recomended Anti. At 35% Which is correct apparently. Doing it since 2008

Can you explain what you mean here? I'm sorry, I'm not following the point or question. Thanks.

All the best,

Peter

RUN The ANTI Freese AT 40% is what the 240 manual says. I run mine At 35% ?

 

[5030]

I do 50-50 in my Kubota's, again dilluiting the full strength stuff with distilled water.
