How often do you see cavitation problems from low SCA in coolant?

[ArtC]

I have a '97 F250; 160k miles, had it since new. I was very dilligent with the coolant additive for the first 10 years or so that I had it and then fell off the wagon! Just had some work done and had the mech check the SCA. He said it was fine... It's been years since I did the coolant...

How long is a treatment good for and how often do you see actual cavitation problems resulting from poorly treated coolant?
Thanks, Art

To the top, I'm curious as well.

My initial thought is how good is your mech? Is he a 7.3 diesel guy? I'm not saying your SCAS are out of spec or anything, just that it would be good to make sure that he took it from the pet**** and not the resevoir.

What is the additive you should add to your coolant? I have read about it but it is always referted to as the "additive"

Haha, the forum censored petc-o-c-k.

Maybe I'm just old fashioned but I change all the fluid every year. $50 just seems to me a better option with all the towing that I do versus a $11 bottle that re-energizes old coolant.
