Can Anyone Pleas Help ID This large Hose???
 

This looks like a coolant hose. It appears to be leaking, but the fluid is clear and slightly oily.

Thought so. I was expecting a pink hue to the fluid (the tank has that color). It appears to be wet at the bottom of the metal clamp, just forward of the yellow dot on my picture.

Can't see anything else that might be the cause, so I was thinking it was from the hose.

is your overflow pipe from resevoir routed straight down? It looks like it might be angle towards hose ? the tiny hose left of word MAX.Mine goes straight down. Looks like some residue by cap as well

Good thought!

However, the drain hose is both dry and extends several inches past the larger hose. I looked at it again and there is fluid gathering at the bottom of the clamp on that hose. I has left a few quarter sized puddles on the garage floor each time it is driven.

It's not going to burst, but a car that leaks any kind of fluid on my floor really bugs me. Goes in Monday because I don't have the means to correctly refill the coolant system.

If it's original- change it. It's 14 years old perhaps?

Yes, that is correct. It is a retaining clip.

I have an independent shop that has the equipment and has done this a few times for me before; once when I had the water pump replaced, and again when the heater core went bad.
