coolant change interval

How is he gonna do that?

Probly not....

And you can often get away with that.
Some times you can't. I've seen several wet sleeve engines where the anti freeze was neglected have cavitation, where they had pin holes from the outside of the cylinder walls in.
Needed a complete engine over haul because of it.

i have read that cavation can occur with improper type of coolant. can't really say more than that...a search here might produce some hits on that subject.

Me I would sooner change coolant than change a waterpump or a radiator. Especially in my Merc as the engine would need a teardown

Please take no offense. Can you valid that with some confirmed documentation?

Something,,, like this??

We need someone patient enough to read and comprehend the article,,,
it is the wrong time of the day for me to read it,,,, :confused2:

I am just kidding,, :laughing: it a short read,, and has pics of the damage!!

I switched to Rotella antifreeze in all of my diesels after I first heard of this.

Haven't seen it in a long time but used to see a lot of radiators get clogged with buildup. Antifreeze solution would be clean and green but the coolant couldn't flow. More than likely people were filling with 50% hard water but who knows.

That lifetime Rotella reads ""fill-for-life" in conjunction with a monitoring program and the use of Rotella ELC Extender" so not exactly a forever solution with no maintenance. I used in in my diesel generator though.

No.
Don't care if you believe it or not, but I do. I've seen it happen on a wet sleeved engines.

PH indicates that the glycol in your coolant is breaking down. As Glycol breaks down (age and heat) it breaks into Glycolic and Formic acid. As it does it lowers the PH of the mixture gets around 7 it starts to contribute to corrosion. The floaty ball tester only tell you how much stuff other than water is in your coolant mixture, and giving you an indication of its heat properties. PH tells you the condition of it.

thanks, this is the info that i was looking for in my original question. was not aware of the PH issue. will continue to change coolant within 5 yr intervals, fairly inexpensive as i do that kind of maintenance on my own. best regards

Thanks for the link. Very informative.

Clearly and repeatedly states SCA in the system can be properly balanced by using a proper coolant filter which contains DCA4. This filter should be changed on the same frequency cycle as the oil filter.

Just curious, how many readers have such a filter in their engine coolant systems?

Makes absolutely no mention of changing coolant to maintain this ideal condition.

Only problem with that link is it is outdated to some degree, as well as being out of country. Tradtional coolants for wet sleeve engines did require addition of SCA's periodically and testing to see if the proper level was adequate to prevent liner cavitation. The newer ELC coolants don't require the use of SCA's and periodic testing of additive concentration. One of the reasons that Cummins, and all the other heavy engine manufacturers, now factory fill with ELC coolants. And the primary reason I have been using ELC coolants for over a decade now. Takes out all the guesswork and provide superior liner protection, as well as added water pump lubrication. ELC coolants are definitely where it is at if one wants the best protection. I use the same ELC coolant for everything I own that as a liquid cooled engine. From my Cadillac on up thru my heavy commercial truck. Even the JD Gator.
