Coolant test

Hey all,

Is there a cheaper alternative to the Rotunda test kit?
It's time to check the anti corrosion strength, and I have owned this truck since new, so no other coolant has been added to contaminate the mixture.

The Accustrip Rotunda kit after shipping is around $85, then more money if I need the revitalizer. At this point, might be better cost wise to drain the radiator and refill.

Is there a budget minded strip I can use to test just what I need? It's a 2015 Powerstroke woth 73K miles.

My opinion only. If you have had no problems, and nothing has been added, then i'd just reset and go on with my day.

That's kind of my train of thought, but the corrosion inhibitor does deplete over time........

You can add the Rejuvinator twice during the life of the coolant.
I've gotten lazy or cheap. I just add the rejuvinator at your mileage and flush at 100,000

Ok, so i did a test back at 45K miles, and not even sure i did it rigjt back then, and it indicated i needed to rejuvenate, so i did.

If i just add it again now, and it doesn't need it, am i harming anything? Is there such a thing as too much?

I just did a flush at 60K miles and kept driving. I tested once and decided I would just do that. Now with the coolant changes I will switch coolants at 100K.
