LubeGard Kool-It Coolant Treatment

[njohnson]

Does anyone know if it is safe to use LubeGard Kool-It Coolant Treatment in diesel engines?

I would like to use it in our three Kubota diesel tractors, but I'm nervous about damaging something. I e-mailed LubeGard last week and have yet to receive a reply.

The bottle says,"Ideal for cars, trucks, RV's, towing applications, and racing/performance vehicles."

"Prevents cooling system corrosion"
"Protects all metals from electrolysis"
"Prevents deposits which lead to overheating"
"Reduces wet-sleeve cylinder liner cavitation erosion"

Please advise!

Thanks.

It's a good product but I do not know about diesel applications. They are slow to respond to email, but they do answer the phone.

I called LubeGard and spoke to a gentleman named Pat. He said that the LubeGard Kool-It Coolant Treatment would be "perfect" for diesel engines because it protects against wet-sleeve cylinder liner cavitation.
He also recommended to double the dosage of the coolant treatment, instead of using one ounce of treatment per quart of antifreeze for gasoline engines, use two ounces per quart for diesels.
