low coolant / add water?

[Sir_Traveller]

My coolant level is about 2 inches lower than the cold level, do I have to buy and add coolant even though I am not driving the RV right now ? ( its hooked up at an RV park ) Can I just add distilled water?

I will eventually add coolant before I drive it in the future of course but my question is regarding the current situation

I appreciate any ideas and suggestions …

Get coolant because you may need to top it off more again if you have a leak.

Definitely add coolant. Do not add water.

If you are not driving it, hardly matters.
If you are 50/50 water/AF and you don't live in the Yukon you can add some straight water.

Gas or diesel? If gasser, I would wait and see how the level looked after it warms up. If low and no coolant to add, I would put in distilled water...but only just enough till I get the right coolant to put in.

If diesel, I would wait till I started it next time and then see what the level does. If still low but visible in the overflow tank, I would wait till I had the correct antifreeze as the engine require special coolant.

Most diesels have over 10 gal of coolant...most gassers, just 6-7 gal and you can get that anywhere.
