Not sure if these have one but it could be a bad thermostat.
i have replace the thermostat, checked the fans,filled with water and it is still overheating. Very often, the waterpump leaks and stops working only years after it was last replaced. Coolant is probably not flowing from the engine to the radiator to be cooled.
1) Is the water pump actually moving coolant? 2) Is the radiator plugged up and not flowing? 3) Getting air flow through the radiator? 4) Radiator cap holding pressure? 5) Something else causing overheating? Timing off, head gasket leak, etc,
The question is why do you think it should? Is there an overheating problem with your Outback?
if it's like my V8 Porsche 914, i had air pockets in the cooling system at the water pump. when air is at the water pump there is nothing to push water. Therefore overheating. Other things to check is water pump and radiator.
Assuming the engine is not overheating, it is normal for the hoses to get hard. The pressure in the cooling system should reach the maximum of whatever the radiator cap is set for, usually 15 to 17 lbs.
Overheating can be caused by several things. Make sure that the cooling fan comes on when its supposed to. Make sure that air can flow through the radiator cooling fins. Insure that the thermostat is not stuck shut, the water pump is working, and that the coolant is flowing properly. One of these would be the most likely problem.
Could be a stuck thermostat in closed position, or defective water pump. Check by squeezing top thick radiator hose and feel for water flowing, when realising, you should hear a squeezing noise. And check if hose is hot.
If you have transmission fluid in your coolant, you need a new radiator. The transmission cooler is a separate cooler located inside the radiator. Apparently yours has sprung a leak. It cannot be serviced separately. First replace the radiator. If its still overheating, then check the T stat. Rick I'm a retired ASE Master/L-1 Technician.

Electric currents flowing at higher rates than the material can withstand.
That means that the radiator is stoped up with trash and engine coolant is not flowing through the radiator.
car radiator is an open system...because hot water is coming in and rejecting heat..this means mass and energy r flowing in and out from the system..it is a control volume through which mass is flowing..
An open circuit won't cause any overheating because no current is flowing. Other faults like ground fault or a breaker tripping should happen fast enough not to cause any overheating either.
