Because the radiator is provided with coolent which start boiling on absorbing heat from the engine.
I just did a radiator swap on my 1991 Range Rover The radiator cost $300 and took me about 1hr to fit it. If your radiator is rare it may be cheaper to have it repaired by having a new core fitted. If you would like to see how to fit a radiator I made a video about fitting mine it ay help you. @makerepairbin
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.
It will raise your boiling point very slightly, maybe 2 or 3 degrees.
Not in any cars that I'm familiar with ... though taking it off would make it easier.
The boiling point of water is 212 degrees, most vehicles now days operate ftom 205 to 215. A 50% mix of distilled water and antifreeze will extend the the boiling point to 265 degrees at sea level. If you go up in elevation the boiling point will decrease, so make sure you have a known good or new radiator cap to prevent premature water boiling in higher elevations
the sound that old cars make are like beep beep and (farts noises or rubles)
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
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.
The degree to make boiling point
because water between shells reaches saturation point, which is above 100c latent heat of steam --
blowoff valve.Pressure when you shift blowsoff and makes that exploding sound
