Because the radiator is provided with coolent which start boiling on absorbing heat from the engine.
mine use to do the same thing, it was the water pump backing up.
It is in front of the radiator and the horn itself can be bad.
Not in any cars that I'm familiar with ... though taking it off would make it easier.
It will raise your boiling point very slightly, maybe 2 or 3 degrees.
the sound that old cars make are like beep beep and (farts noises or rubles)
It depends o the cars make model and year. Mine is mounted behind the gill just in front of the radiator below the hood latch.
Sometimes it is not actually "boiling", but bubbling. Start by getting a new radiator cap. It is the first thing you should do, and is easy. *MAKE SURE YOUR CAR IS NOT HOT WHEN REMOVING A RADIATOR CAP* When air enters the closed/pressurized cooling system, the air ends up in your reservoir tank and bubbles the top. ! Chris Hey L==Either the engine coolant level is extemely low or the temp sending unit is incorrect. Make sure the radiator is full of coolantWHEN THE ENGINE IS COOL. If it still does it, have the temp gauge checked. GoodluckJoe
First make sure the radiator is full of coolant ;this is where the heat comes from. If it is full , then change your cars thermostat. The stat is located at the lower end of the top radiator hose within the water outlet. That should do it.
Replacing a radiator costs $400-500 for passenger cars depending on the type of coolant used and the age, make and model of the vehicle. If you know a lot about cars you may be able to replace the radiator for cheaper doing the labor yourself.
blowoff valve.Pressure when you shift blowsoff and makes that exploding sound
The degree to make boiling point
because water between shells reaches saturation point, which is above 100c latent heat of steam --
