I have a crack in my radiator, and my car overheated, and damaged the thermostat. What do they do?

The radiator is part of the car's cooling system to ensure the engine stays at an efficient operating temprature without over heating. The radiator holds water and other chemicals (to prevent the water from freezing in cold weather) and allows air to pass over the coils holding the mixture to let heat off to the surrounding or passing air. The Thermostat works off of the temprature of the cooling water mix in the engine and opens to let the hot water out of the engine once it reaches the correct temp so that the engine does not get too hot or stay too cold. As the engine does need to heat up some to get to an efficient opperating temprature.

The radiator displaces heat generated in the engine to the air moving through the radiator core. The thermostat controls the operating temperature of the engine. If your vehicle has a 180 degree thermostat in it then it will maintain at least the 180 degree coolant temp inside the engine. As the coolant reaches the correct temperature the thermostat open and allows the 180 degree water to flow to the radiator and cooler coolant is drawn in by the water pump. As the cooler coolant reaches the thermostat then it closes and holds the coolant in the block to allow it to absorb the heat until it reaches the 180 degrees then it exits the engine and goes into the radiator. The heat of thermostat varies by manufacture. I have see 165, 180, 185, 190, 195, and 205 heat ranges. Make sure you install the correct one for your application. Wrong heat will really mess up some electronically controlled engines.

the radiator, has the coolant flowing through it and as air is passed through it a lot of the heat of the coolant is removed. the engine has a pump that takes the cooler coolant out of the radiator and flows it through the block to cool the engine then back to the radiator (to be cooled) the thermostat, regulates the amount or coolant the engine gets from the radiator by restricting the fluid. when the engine is cold it will not run as efficiently as when it is at the proper temperature and the thermostat handles that. the thermostat is set to open at a certain temperature and if the engine overheats, sometimes the thermostat needs to be replaced because the heat damaged it.

The radiator serves to cool the water that is circulated through the engine to keep it cool.

The water passes through a series of finned pipes which disapate heat to the outside air.

The thermostat is a device which measures engine temp, and then controls the amount of water that is passing through to cool it. The main function is to keep the engine at an optimum operating temp.

Depending on how long the car ran hot there are many other components that might be damaged, not the least of which is the cylinder head

The thermostat measures the engine temp the radiator cools the engine. It's at the front and uses the air flow through the grill to disapate heat.

Chances are because your radiator blew, and the engine overheated, it fried the thermostat. It'll need to be replaced so that the engine knows when to cool

The radiator is made of lots of fine tubes, water circulates round your engine cooling as it goes. The now hot water enters the fine tubes in the radiator, the fine tubes have air blown over them as you go along cooling the fine tubes and the water in the tubes, so that the once hot water is cool and can go round the engine again. The thermostat on your car probably jammed shut causing the damage. The thermostat acts as a temporature regulator making sure your engine is at the right temporature

The engine gets really hot when it is running: after all there are explosions inside by design. Thermostat keeps track of the temperature and controls air and fluid flow from the radiator to the engine to cool it. Radiator fluid absorbs heat from the engine and cools it in the radiator by temperature exchange with surrounding air.

The radiator cools the engine water..the termostat opens when the engine gets to a certain temperature and lets the water circulate through the radiator to keep the engine running cool

When a car is driven, the engine generates enough heat to destroy itself. Because of this, your car is equipped with a cooling system to protect against damage and keep the engine within the correct operating temperature range.

The radiator, an integral part of the cooling system, is designed to protect an engine from the destructive forces of too much heat. The radiator's function is to lower the temperature of hot coolant coming from the engine by cooling air that passes through the radiator.
i think it is clear enough...................good luck¡

it keepsthe engine from burning up from the heat that it generates in the combustion process.
