Cleaning Cooling System

The parts manual calls it an "inlet" elbow.

Here is a flushing tool made by Eugene.

For reference:



Here is the crud:
Note the "lime" in the upper part of the passage near the valve seat. This is what washing soda will scour out. It is a fairly powerful base (alkaline)- not as strong as lye but plenty strong. This is why it has been used as a booster for laundry detergents to counteract hard water

You can also use cascade dish washing powder. Caterpillar actually sells it by the box, not even relabeled, to use to clean out cooling systems.

It works GREAT if you have a cooling system and have a oil cooler burst, making a milky mess of the cooling system.

While IH defiantly made the best recommendations possible for when the cubs were made, technology has progressed and sometimes there are better alternatives.

Interestingly enough,

Ingredients/Chemical Name: Water softeneing agents (complex sodium phosphates and sodium carbonate),
cleaning and water spot prevention agents (nonionic surfactants and chlorine bleach),
sodium silicate, sodium sulfate, suds control agent, colorant and perfume.

I don't know exactly what the "complex sodium phosphates" are but they must be detergents of some sort. Sodium carbonate is where we started. Sodium silicate is commonly called "water glass" and is often used as a stop-leak (including name brand packaged stop-leaks).

Sometimes it isn't clear how much of the progress is in the packaging.

I think the difference is the perfume.
Instead of just working, it now smells clean and fresh!

Well Bob, you're absolutely correct that it's the inlet!!!! I'm amazed at how infrequently my brain seems to work now that I've become an "older senior". I apologize for the fuss!! Al D
