If they are collapsing after the engine is off, the rad cap is bad. The cap needs to allow pressure back in as the engine cools off.
In line on the heater hoses on the passenger side of the engine. Has a small vacuum line to it and both heater hoses go through it. The heater hoses are smaller than the radiator hoses and go through the firwall.
Low coolant? Radiator plugged or restricted? Water pump not circulating coolant? Hoses collapsing? Thermostat not opening?
there could be ,the vent line if split can cause this dtc
jack the front end up and support it then remove one of the heater hoses
No, it is not required. You can remove it and splice the heater hoses together.
check radiator cap for wear. defective cap can cause radiotor hoses to collapse.
fatigue
Replace with reinforced hoses Check radiator cap for proper pressure
Radiator cap
the hoses leading to and from your radiator might be clogged. If you had a rusty radiator, the rust may have clogged the hoses that carry the coolant. you should check all your hoses and even flush them out.
Radiator hoses are made of rubber and over time these units fail due to the environment. When they fail the rubber can get dry rotted which will cause the lines to flatten and crack.

Most definitely. A blown head gasket can cause the temperature to rise and put back pressure into the radiator, therefore possibly causing the radiator hoses to blow, or even bursting the radiator.
did you replace radiator hoses i have seen hoses collapse and cause overheating while driving and radiator could be clogged. also did you bleed your cooling system according to owners manual
Drain cooling system Remove fan shroud Disconnect transmission lines Disconnect upper and lower hoses Remove bolts at top & side of radiator Lift out of lower supports
Low coolant? Radiator plugged or restricted? Water pump not circulating coolant? Hoses collapsing? Thermostat not opening?
2 radiator hoses / the top radiator hose comes from the engine thermostat / and the bottom radiator hose returns to the engine water pump
