Coolant leaks everywhere: Help
Ok so I started noticing random leaks in multiple places under the truck, so I went in for a closer look.
Nothing leaking around the degas bottle; deltas are good, performance is fine, egr not leaking.
Turns out I've got leaks all over the place. Some are clearly coming from various connection seals (mostly around the radiator), others I haven't been able to pin down.
I've taken pictures to illustrate:
These are from below the radiator:

Below fan
Passenger side Radiator hoses:
This one is directly above the front differential, which I assume is a connection to the water pump:
There is another above the driver frame rail that I can't see.
Is this simply a bunch of failed seals and hoses or something more sinister at play?
Truck has 250k miles, and is not driven very much. Leaks only occur when truck is hot.

I'd be more inclined to call that seepage than leaks. First, have a reputable garage do a cooling system pressure test. If they can also do it hot, then so much the better. Make sure the cap is good too.
The oil leaks look minor because there's so much dirt accumulated. A real leak looks clean. If you can wash everything down and then use dye in the oil you can find the leaks with a black light.
How much oil/coolant is actually leaking out? Big puddle? Little drips?

It's little drips forming puddles about 8 inches in diameter. Although, I sopped it up with a paper towel this morning and it doesn't appear to be coolant (i.e., clear and no smell). It seems to be water.
Before work I let truck warm up for about 30 min, then, on my way (20 mile drive) I did several WOT test. Got the EOT up to 205, ECT was around 197-198, and EOT quickly cooled when I got out off the aggressive throttle.
When I arrived, coolant level hadn't moved, but the inside of my front driver-side wheel well was covered in liquid that sprayed from somewhere. I assume this is a water leak.
Also, after the WOT test, a new small puddle began forming under the front passenger door (pretty much right under the frame rail). Also appears to be water. This puddle was further under the truck (even with front door) whereas the others are closer to the front (below the radiator and differential).
Could this be the manifold rubber donut I've read about?
