The cooling system is under pressure and opening the cap can spray you (and other things) with very hot coolant.
Common signs that a radiator has blown include coolant leakage under the car, overheating engine, low coolant levels, and visible cracks on the radiator. It is important to address radiator issues promptly to prevent damage to the engine and ensure safe driving.
When the cooling system is overheated, the coolant is at pressure. Removing the radiator cap will release the pressure, and allow the coolant to boil, probably splashing you with boiling-hot radiator fluid. Your arms and hands will certainly be burned, and there's a good chance that the boiling coolant will splash your face. You wouldn't like it if that happens.

A "bad" thermostat is probably one that is sticking. If it sticks open, the engine coolant will circulate through the radiator at all tiimes, making the car hard to warm up in the winter, and slightly less efficient according to the laws of heat engines. If the thermostat is stuck closed, the coolant will never circulate through the radiator, which could cause the engine to be damaged by overheating.
Yes , if the engine is cold
Two different tests you can try. To check the radiator fan, raise the hood and start the engine. Wait until engine warms up to normal operating temperature and see if the fan turns on. If the fan doesn't turn on, the problem lies in a faulty relay or a bad fan motor. If the fan turns on, the problem lies elsewhere. To check the water pump and/or thermostat. Raise the hood, remove the radiator cap and start the engine. Keeping a safe distance, you will peek through the radiator filler neck for activity. When the engine reaches normal operating temperature, the thermostat should open and you should be able to see water circulating. My bet is on either a faulty fan/component or a stuck thermostat as your overheating problem.
Yes.
To open the radiator in your Hyundai Excel, first make sure the engine is cool to avoid burns. Locate the radiator cap, which is usually on top of the radiator, and turn it counterclockwise to release any built-up pressure. Once it's safe, you can fully remove the cap to access the coolant. Always check the owner's manual for specific instructions related to your model.
As long as the engine is running you will have power assisted steering. With the engine not running you will not have power assist and it will be hard to turn but turn-able. If the engine is overheating it would be wise to pull over and park when safe to do so and shut off the engine before expensive damage is done to the engine.
You will not damage the engine but you can damage the radiator if you use any high pressure. If you only flush and apply no pressure you will do no damage. Use a chemical flush and a water hose and you will be safe.
Pull over when it is safe to do so then shut the engine off. If you continue to drive the vehicle catastrophic damage to the engine can occur.
It will be safe to drive short distance as long as the car does not over heat. You can top up the engine coolant or use water/coolant mixture till you fix the problem which could be leaking hose pipe. leaking radiator or faulty radiator cap
