Your garden hose acts the same as a solar collector. The sun shines on the hose which heats up and in turn heats the water inside it. You may see some houses that have solar hot water panels on their roof. They have pipes that run to and from them. The sun warms up the water that is passing through them and sends it to the hot water heater in the house. Since the water is already warm or even hot, the tank does not have to use as much energy to heat it. The darker your hose the more energy from the sun it will absorb making the water hotter.
if it is a braided hose, it just deteriorated due to age.
I don't know if this is what your looking for but, you can attach your hose to your hot water connection to your washer. the water won't come out scorching hot.
There is no valve, it is probably clogged up.
It is probably sediment from the hot water heater, you may need to flush out the hot water heater tank, all it takes is a garden hose.
what if my top radiator hose is very hot and the bottom hose is cold,would that be a bad water pump?
B'coz water is a very good coolent i.e. it can absorb the heat from the object & gets evaporated..
hot water is hotter cause hot water is always hot
It really depends by the atmosheric temperatur,once this is known the temperature of the water from the hose would be answered more accuratly.
In HD they sell a braided SS hose specifically for that, about $15
Water is always H2O whether it is hot water, cold water, ice, or steam.
Your water flow comes out of the engine through the upper hose, into the radiator. The lower hose is cooler because the radiator has done its job; it cooled the water!
It is probably not the hose. It is probably the inlet valve the hose connects to on the washer. The valve open electrically and they can go bad. They are easy enough to change and should not be more than about $20. Just to check, shut the water off, take the hose loose from the washer and see if water come out when you turn it back on. It could also be the temperature control, but the fill valve is much more likely.
