2 oz Coolant $14.00

[Full-Timers]

I noticed my overflow reservoir’s level never changed, cold or hot. Also after running, the coolant in the reservoir was cold and the radiator cap was cool to the touch. So after it cooled I removed the cap. Just as I though, low on fluid. So off to Walmart I went. $14 for Prestone’s Dexcool equivelent. It only took about 2 ounces to top it off (should have just used water), and still no change in reservoir level when hot. Does your reservoir level change?

My level does change from cold to hot.

Mine changes when really hot. Did you get it hot enough? If so I would change the radiator cap. When they go bad they usually overflow too much into the reservoir tank but it could also be stuck closed or otherwise opening at the wrong temp (defective or be the wrong spec cap). Greg

I also had the same problem. I purchased a new cap and all is well now.

How The Motorhome Coolant Overflow Reservoir Works

I will not go with an equivalent or compatible product. I will only use a product that is labeled, "Dexcool." I pre-mix a quantity of coolant 50/50 and store about 1/2 of a gallon in my compartment. I have not made an adjustment in the cooling system level for quite some time now.

My coolant level is right on the Cold mark.

I would like to add the suggestion that you re-check to radiator level...you may have to keep adding a little at a time to get it completely full. THEN the overflow / backflow situation MAY work as designed. Good luck!

That was my though too. I will check it again.
