Thanks Gerald. Was under the impression it was a chemical reaction, I learned something new today! Guess a person is never too old LOL!

Had the definition of electrolysis in school a long time ago but I went and looked it up just to get it right. I'll put it here in my own words...........Electrolysis is an electro-chemical reaction between different metals. Just like how some folks on the forum have cleaned rusted metal parts immersed in some form of conductive liquid and opposite some home made electrodes and using a battery charger hooked up to each metal. Leave it charged long enough it will eat away at the good metal too.
Then there is just plain oxydation which is simply corrosion. Both of these and cavitation that a diesel is prone can kill an engine given enough time. These are three different problems and cavitation is the biggest problem in a diesel IMO. Edited by Lonn - 28 Dec 2017 at 5:45am |

the film I saw that Cummins put out,said the liner expanded under firing and "snapped back" in place causeing void between water and wall causeing high heat on wall surface.When water moved back to wall,it was boiled and that steam bubble would blow a hole in metal (little by little). The additive coated liner to form protective layer to offset "steam damage". It doesn't change what's going on,it just protects against damage. This is for cavitation erosion.Electrolisis is different animal.

Cat EC-1 equivalent is an excellent diesel coolant that is available anywhere, and many aftermarket coolant makers offer a EC-1 equivalent.
I need to find a coolant filter without the additive brick inside, as I still value the filtering ability of having a filter, but I would imagine running a regular pre-charged filter is a no-no with extended life coolant. |

I don't know for sure but I think the coolant "filter" is really a device primarily intended to keep the additive amount up and there isn't any coolant cleaning in the can.

They do indeed have filter media in them and they do filter the coolant. When IH came out with the coolant filter kits we installed a lot of them on older tractors. We had several that after several days the the filter quit warming up when the engine was run. We cut the filter apart and it was completely plugged with the brown sludge that you typically see at the bottom of the block when you pull a wet cylinder liner out.

Picked this up at Rural King. Has the additive in it. |

I have an EL-300 Kubota single cylinder diesel engine that makes about 4.25 HP on a good day. We use it to drive a large frame alternator to recharge our battery bank when the sun doesn’t shine and wind doesn’t blow. It runs at about 1,650 RPM. Is my little engine at risk from this effect? It is a wet sleeve engine, with a little over 10,000 hours and runs like a champ.

That little Kubota probably don't have enough bang to swell liner on power stroke but I would follow Kubota's direction on your coolant.HD coolant can't hurt it though. 10,000hrs is a lot so you're probably ok either way.

My owners manual and shop service manual don’t mention anything about special coolant/antifreeze. Owned the engine since new over 17 years ago. Never been seriously hot. Changed oil like clockwork. Kept the valves adjusted. Take the injector out/apart ever so often and soak in lacquer thinner. Take the radiator off once a year and pressure wash the thing and the sleeve looks pretty clean. A really sweet engine that the EPA has banned.

Coolant filters are a good idea to add to your 6.0/6.4 powerstroke. On the 6.0 mostly to catch the debris that will clog the oil cooler. Using a precharged filter is a no no as that will clog the cooler too. 6.4 has problems with cavitation on the front cover right behind the water pump. When the Ziegler Cat people were running 6.0s they switched them all to Cat EC1 and then I did far fewer oil and EGR coolers on them.

Baldwin does offer some coolant filters without any coolant treatment in them. Don't know about all applications though.

I just found Peak "Final Charge Coolant " at
Menards for $11.49 per gallon. Label says it meets many manufacturers including Cat EC-1 and Cummins. Should be under $60 for a refill. Thanks for the information..

You didn't fall for the "PREMIXED" anti freeze, DID YOU??

Bob, did you mean Fleet Charge? Does it look like what I put in my post above? If so, its full strength not a 50/50 mix.

There is a difference in pre mixed vs full strength other than one is ready to use and the other requires mixing. Premixed uses de ionized water. Probably not as big of a concern in the diesel world unless there are electronics being cooled as well.
