Upper rad hose is squishy... normal?

Hello, I'm a new Jeep owner with what you will likely consider a dumb question. I was under the hood the other day, and while checking the upper rad hose I noticed it was full of fluid, while the reservoir seemed rather low. Is this normal? I've had no issues with it so far beyond a small coolant drip below.
This is only my second vehicle; I've long wanted a Jeep, and I want to keep it reliable so I can get out & about this winter.
Also, how in the world can I get those darn plastic fenders off? I had to paint them while on the vehicle, but there's a rust patch I need to deal with before it penetrates, and the fender's sitting right on it. I'd rather not have to do any cutting.
Thanks beforehand for any responses.

The radiator cap has a valve to allow expanded (hot, normal) coolant to flow intothe over flow bottle. When Engine cools down (hours) it sucks some back in-usually the same amount it had pushed out when hot. This is normal-Every vechicle that is water cooled has this feature to deal with expansion. SO- yes the top radiator hose should be full of coolant whan you mash it. Now if your vechaicle is old and the hose is spongy/sloppy feeling -that is different, and usually means it is detoriating. (usually they get hard-and will have a crunch feel). How old and how many miles on vechicle? Does you temp gauge run in the normal range?

It's a 99, so about 14 years old with about 151,000 miles on it. I haven't driven it very far or hard yet, but it's never gotten very hot. I was just a little concerned about the coolant sitting up there, since the hose clamp seems a little too close to the engine and I don't want the metal tube to corrode off as a result of liquid sitting in it.

As long as it has antifreeze/coolant (about 50/50 mix) you should not have corrosion (maybe it it just sets several years-not running). If there is some at the hose and fitting-it probably is leaking a very small amount there. Wouldn't hurt to drain and fill with new antifreeze/coolant. Either use the pre-mixed stuff or dilute your own (I like 60% coolant-40% distilled water). DO not use water out of the facet, or bottled drinking water. some use dionized water. I prefer distilled. Either way stay away from water with minerals, etc.

Hose should be squishy no cracks or dry rot showing. After it gets to temp and the thermostat opens you can actually squeeze it and feel water flowing by. Good flexible squishy rubber hose = good while dry cracked hose = bad.
