Coolant loss

Searched to no avail.
On a recent trip, I was checking the engine oil, Tranny etc, and found my coolant low.
I put in 1/2 gal, and watched as the level kept dropping. Added another 1/2 gal and it filled the tank to the proper level.

Now I will admit that I had not checked in a while, but there are no visible leaks anywhere. No visible signs in the engine, or transmission oils.
I drove about 6 to 7 hundred miles since then, with about 550 miles pulling my fifth wheel,with no visible signs of loss anywhere.
Any ideas would certainly be appreciated.

Do you see any water/coolant stains on the lower radiator hose (under the water pump)?

I have seen a small cracks in the degas bottle that lets fluid out when the motor is running and because the motor is hot you never see liquid just a white residue if your running gold fluid. Over time it adds up quickly.

Not sure if ti happens with the newer ones but many 99 owners had to replace their injector cups because of coolant loss.

I had a pesky small leak at the bottom hose clamp where is joins the water pump. It took a while to find it. First I thought it was the pump but some cleaning and a new clamp solved the problem. That was many miles ago ! Look for residue or staining, that'll be the best way to find it. Good luck !

Thanks everyone, but I think I found it. Top heater hose had a drip hanging this A.M. Cut some off and I am back in business.
I will be sure and keep a better check on it.
Many thanks to all who responded. As always you are the best. Jim

Glad you found it. Probably drying up as soon as it hit metal.
