Radiator cap? coolant leak

Jhill

Yes that is correct. I couldn't see the images clearly on my phone, gets blurry when zooming.

Looking at the image as clearly as I can. Seeing the white around the metal elbow and the coolant stains below it. I suspect the small hose may be seeping and coolant wicking along that bend and then on top of the coolant pipe. Really need to do a pressure test to know.

Thanks! That should nail down what's really leaking.

Also when the coolant is at operating temp and the system gets pressure on it, move the small hose and see if coolant comes out. I had a truck that had a coolant leak and once I moved the hose coolant started shooting out of a pin hole sized hole. I would also get the cap replaced as well. And as people have previously said, fluids can move in crazy ways.

Last but not least, coolant can sometimes seal an area where it is leaking from once it dries up. So try cleaning up the coolant and put pressure on the system.
