Collapsed Upper Radiator Hose

[2bits]

OK here is a long drawn out problem.

My Old Tank's temp light came on about two months ago and I replaced the thermostat at that time. No help.

I then noticed that the upper hose was collapsed so I replaced both upper and lower hoses and the lower hose has the wire inside it.

Then I replaced the radiator. still the truck would overheat. Then I replaced the Cap with a Stant radiator cap.

The car still would overheat and the coolant would come out of the overflow bottle.

This weekend I replaced the Water pump and the thermostat again and went to the dealership and got a new stock radiator cap.

This morning I cranked up and let the car warm up and checked it out.

After it was warmed up I opened the cap to check the flow and noticed that the water was low so I topped it off and watched it for awhile, and it started spitting back out. This is driving me crazy. The water is getting hot so I know it's running through the engine.

I started cussing like a sailor and put the cap back on and guess what I noticed then......

The upper hose collapsed when I put the cap back on.

What's wrong with "My OLD TANK" ?
