Deuce Over Heated Today. Low On Coolant?

[Valence]

Just go to your parts store and get antifreeze made specifically for diesel engines. Color doesn't matter. Never put automotive anti freeze in a diesel engine.

Thanks welldigger, you seem to be answering all my "noob" questions!

One more thing. Flush the system and start fresh with all the same brand/type anti freeze. Oat and regular diesel anti freeze with sca additives do not like each other.

Funny, I've been in the equipment repair business for years and I've never seen or even heard of special antifreeze for diesels. What's it called?

Edit: Are you talking about ELC or the Coolant for Heavy duty engines?

Here's a good article about diesel engine coolant and why you should use it. It also details the difference between Oat and sca additives.

The industry for years now has used these additives. My company has used the extended use anti-freeze but it was not worth it in the long run. We just test each bus every 6000 miles at inspection time.

Oat anti freeze is coming standard In many new trucks. Not saying it's better or anyone should use it. Nothing wrong with sca's either. Just be aware of what your using and how to use it. Do not mix the 2!

I will definitely make sure I continue buying Diesel approved anti freeze from now on. The reason I've never heard of it is due to me not paying enough attention. We have been using it all along. Also, the Baldwin coolant filters we use have an SCA "Tablet" in them. But I will definitely look at the coolant I use a lot closer from now on. Thanks Welldigger for the info and thanks OP for this thread. Some great information here.

My understanding is that special coolant is only needed for wet sleeve engines to prevent cavitation erosion. The multifuel has dry sleeves and is not prone to cavitation erosion.

This is true, but the extra insurance doesn't hurt.

!%#$!$$%!!!?? The multifuel is NOT Wet Sleeve?

 

[JasonS]

IMHO, if it isn't needed for the 5.9 Cummins it isn't needed for the multifuel.

 

[Jeepsinker]

No, the multifuel is not a wet sleeve engine.

Before ford switched coolants in the later 90's the 7.3l powerstroke was prone to cavitation failure. It's not a wet sleeve block either. Food for thought.

Agreed, it can also depend on the design but is usually confined to wet sleeve engines. That said, I have been following this forum since 2005 and I can't recall even one cavitation problem with the multifuel.

I agree. I just err on the safe side since it's easy enough to do. That, and the way I drive my deuce if cavitation can happen it will happen in mine. I'm not afraid to hold it to the governor all day long. I know it's not the greatest idea but it's how I drive it.
