I'd go to Cat or Cummins and purchase some additive for the coolant system and let it go as long as you've taken care of it...

We add back the additive once every 2 years and just keep tabs on it... .

When we do change it, we add new coolant and distilled water...

Is there a test kit for our truck's coolant additive levels ? Baldwin makes one using little paper strips for my ancient 855's coolant. If not, and I've not added much water at all over 104,000 miles, how much additive should I add ? Baldwin makes different ones for different generation engines, I was told, I use the something-007 on mine ( it's a 4 digit number and I can't think of the first one ).

If you change it you need Zerex G-05 formula. You can get it at NAPA and Grainger.

Also your valves should get checked and adjusted. You got a few more miles till it's required but it's eisier to remember avery 100k.

Keep an eye on your water pump too, they're prone to leakage or failure.
