Checking Dex-cool PH and conductivity

[sprite1741]

I check the PH and conductivity of my antifreeze every 6 mos. I don't see much talk on here. Does anyone else? It's so easy with a digital voltmeter and some PH strips. No special equipment needed. I never have Dex-cool troubles, and the ones I read about are from failure to maintain and other complainers that like to complain. The PH is always around 8.5. I change by conductivity which starts to change when the corrosion inhibitors are getting weak and I only do a drain and refill. I posted a link with some Dex-cool specs for PH and conductivity, if anyone is not doing these simple tests. https://www.getahelmet.com/jeeps/maint/dexcool/

The coolant test strips have a shelf life of 6 months. So kinda expensive.

No, I replace it once every 5 years for $20 or so dollars and don't worry about it (G-05).
