Adding Coolant to a Thor Palazzo / Cummins Diesel

Yes, I am new to the RV community but am anxious to learn and help. On a recent trip, I received a "Low Coolant" warning followed by a "Check Engine" warning. I pulled over and let the engine run for less than a minute and both cleared. I started back up the hill and after a couple miles, the same thing happened. Knowing I was near the crest, I persevered and the warnings ceased and I made it home without incident. I checked the coolant level after the engine cooled and it is below the MIN mark on the clear plastic reservoir.

My Question: Do I simply uncap the reservoir and put it in until it reaches the MAX mark or is there a special procedure which needs to be followed? Also, I purchased 1 gallon of Zerex Extended Life formula for Diesel Engines. It is not 50/50 but is it OK to cut this to 50/50 and use it in the Cummins engine?

I appreciate any assistance. There is a tag near the radiator which described opening and closing valves and running the engine but it does not say where the valves are nor where to add the coolant. Other searches have been worthless.

Use the anti-freeze your Cummins Owner's Manual specifies. The Zerex Extended Life may be fine, I don't know. In any event, you can add distilled water to straight anti-freeze to make it 50/50.

Yes, simply uncap the reservoir and add until it reaches the MAX mark when its cold.

Sometimes when going up or down a hill or stopping fast that light will come on.

Yes, you just pour a 50/50 mix into the reservoir - no special precautions or procedures. Dilute with pure water if possible - large amounts of minerals in the water ("hard" water) contribute to long term cooling systems problems. Since you are just topping off the coolant, buying distilled or spring drinking water is not expensive.
