I was told that an anti foaming agent will help to preserve the water pump. True or untrue? Reason I ask is I know the water pump on my brother in laws truck is the only thing he has had to replace in the first 70K on his 05. And that was replaced at around 35K. This guy says that the bubbles created act as a blasting agent as it runs through the water pump. Kinda made sense to me. Besides, the coolant just cools so I figure no foam is a good thing. (Fluid would be denser to absorb heat in the block more effeciently, Right?)

If your using the required HOAT coolant (like Zertex Z05) & distilled water then there is no need to add any anti foaming agent or any other additive to your cooling system.

I figured that, so then I ask has anyone had to replace a water pump yet, and what was the mileage, and did you look inside to see the condition. Still no one has commented on the use of anti foaming agent, does nobody use it?

This is what I'm using, called RMI-25:

I added Purple Ice to my truck when New and really seems to help.

I am using DEI's Radiator Relief (Diesel)

Product Description
Radiator Relief™ for Diesels supercharges your radiator by transferring heat more efficiently through the radiator. Similar to the original formula this proven coolant additive will reduce your operating temperature up to 30°F degrees and reduce engine wear that occurs during extreme heat.

NEW Radiator Relief™ for Diesels is also formulated with a corrosion inhibitor that reduces mineral deposits. This is the first additive that maintains pH levels that otherwise fluctuate over time resulting in core damage.

* 30 degrees lower operating temperature
* 50% quicker warm up
* No mixing required; just add to cooling system!
* Compatible with water and all anti-freeze mixtures
* Safe with all alloys
* 100% Biodegradable, Non-Corrosive and Non-Toxic
* For use in all water cooled engines

What does Radiator Relief do?
It will lower operating temperatures as much as 30 degrees and provide 50% quicker warm ups which results in lower operating temperatures thus more horsepower!

Is this product compatible with anitfreeze?
Yes! Radiator Relief is safe to use with just water or any antifreeze mixture that is available.

How much is a bottle good for?
A single bottle is capable of treating up to a 15-quart system. Simply drain and add.

Do I have to flush out my system to add this?
It isn't necessary to flush the system on a newer vehicle, but we recommend using DEI Radiator Relief FLUSH to thoroughly rejuvinate the system on higher output vehicles. The NEW Radiator Relief can be added right to the coolant system. Just drain a quart to make room for a single bottle and add any additional water to completley refill the radiator or radiator reservoir.

How does it work?
The unique physical properties of DEI Radiator Relief provides the following benefits- the addiditve itself has a viscosity of 33 percent less than water, reducing the resistance to heat transfer. This allows the heat of combustion to move from the cylinder heads and cylinder bores into the coolant with less resistance where the encapsulated heat is released to the core tubes quicker when it reaches the radiator.

I use Redline Waterwetter along with Z05 (Fleet Charge in the 94). Redline products have never let me down.

How is a product going to lower your operating temperature when there is a T-stat that controls as to what it will be. There is a reason the T-stat is set to a certain operating temperature. There are sensors and switches that do not function until the engine gets up to operating temperature and the ECU will be getting signals to run the engine in a cold temperature (closed loop). Sounds like snake oil to me.

Also running Redline WaterWetter. Didn't see a change in operational temperatures but did noticed after a hard run (like towing) the engine temp drops much quicker while idling.

I've never in my life time used an anti foam additive in any cooling system and I don't know anyone who has. As for the condition of the water jacket when a water pump is changed and how it will look all depends on the age and if the cooling system was taken care of properly. As for mileage of a water pump I've heard of them going out in as little as 36K and lasting over 200K.

Antifoam is primarily used in wet liner engines. A liner is extremely hot from combustion and has to be surrounded with coolant. If there are air bubbles or foam in the coolant it leaves little spots for the water to boil against the liner. When the coolant does hit that tiny micro-spot of liner where the air bubble was the coolant instantly turns into steam and creates a tiny pit in the liner. This reaction happens constantly and will erode the liner to the point that coolant enters the combustion chamber.

Our B-series engines have a block without sleeves so antifoam for that purpose is not needed. The water pump failures we see with our Cummins is primarily shaft seals. Antifoam is useful for water pumps when the impeller erodes down from implosion just like the liners. I have changed MANY water pumps over the last 12 years and have yet to see a water pump impeller fail from erosion.
