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)
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.
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.
The cost of a radiator replacement on an old car can vary widely depending on several factors, including the make and model of the car, the type of radiator needed, and labor costs in your area. Generally, you can expect to pay between $300 and $900 for a radiator replacement, which includes both parts and labor. For a more accurate estimate, it's best to get quotes from local mechanics or repair shops.
