The cap is faulty, replace it.
The radiator cap may not be getting hot because it is located in a separate reservoir from the radiator itself. It is designed to maintain pressure within the cooling system and does not directly contact the hot engine coolant.
To pressure test a radiator cap, you will need a radiator pressure tester kit. Remove the radiator cap, attach the pressure tester to the radiator neck, and pump it up to the specified pressure level. Observe for any leaks or pressure loss to determine if the radiator cap is functioning properly.
You should replace the radiator cap if it is leaking coolant, not sealing properly, or showing signs of damage. A faulty radiator cap can lead to issues like overheating, coolant loss, or air entering the cooling system, which can cause damage to your engine. Regularly inspecting and replacing the radiator cap can help prevent these problems and maintain the efficiency of your cooling system.
When a radiator cap does not retain pressure, the coolant can boil at a lower temperature, leading to overheating of the engine. This can cause damage to engine components and potentially result in a breakdown. It is important to replace a faulty radiator cap to prevent these issues.
Radiator caps are pressure relief valves. They are rated at "pounds per square inch" and are designed to release some pressure from the radiator if it gets too high. If an engine overheats it can boil the coolant and this will cause the radiator cap to let out steam. Radiator caps DO lose their ability to regulate pressure and can release too soon. If the engine has not overheated, have the radiator cap tested and replaced as necessary.
It should be printed on the radiator cap. Most are around 16 psi.It should be printed on the radiator cap. Most are around 16 psi.
You likely need to replace your radiator cap - the rubber seal in the cap is worn.

If you have a threaded cap on your coolant reservoir that is your " radiator cap "
No , the " radiator " cap / pressure cap is the thread on cap on the engine coolant reservoir
The radiator cap is on top of the radiator.
the radiator cap is on top of the radiator you idiots
A lot of vehicles don't have the radiator cap on the radiator , they use a thread on style cap on the engine coolant reservoir ( that is the pressure cap / radiator cap )
The radiator cap is located on top of the radiator.
The thread on cap on your engine coolant reservoir is your pressure cap / radiator cap
The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap
The thread on cap on your engine coolant reservoir is your pressure cap / radiator cap
