Engine oil is not going to freeze in your engine. It will get very thick but will not freeze.
Antifreeze helps prevent a car's engine coolant from freezing in cold temperatures and also helps regulate the engine temperature in hot conditions. It prevents the cooling system from overheating or freezing, ultimately protecting the engine from damage.
To prevent the coolant freezing, to help keep the system clean and prevent corrosion and to make the coolant more efficient in cooling the engine.
To prevent the water turning into ice
The preheater warms up the engine so it will start easier and in freezing weather will help to avoid freezing of the coolant.
If you are plugging in a battery charger connected to the battery, yes it will charge the battery. If you are referring to plugging in the block heater, then NO it will not charge the battery it will only warm the oil in the engine block. If you are referring to plugging in a battery heater then NO it will not charge the battery and will only keep it warm.
Yes. You can freeze the water, making it expand, or you can add cold water to a hot engine, shocking the block. You prevent freezing with antifreeze. You prevent shock by never adding water to a hot engine. If there is enough water in the engine to have the water pump provide circulation, you can add water SLOWLY, but you should really only add water to a hot engine when there is very little to add.
In the computer. If check engine light is on you can get them by plugging a reader into port under dash,.
Most diesel engines are hard to start when it is cold. Plugging the diesel engine block heater in will help the engine start.
It has a much lower freezing point than water. if the coolant freezes it expands cauing pressure damage or even leaks. It also contains anti corrosion chemicals to prevent rust inside the engine.
The can if they are built that way.
"Freon" is the product name of the refrigerant GASused in air conditioning systems. Freon is compressed and expanded to cool the INSIDE of the vehicle.Antifreeze is a LIQUID that is circulated through the engine to keep the engine from melting down. When an engine is running it generates a lot of heat. If the heat is not dissipated, the engine will fail. Water is used to cool the engine and antifreeze is mixed with the water to prevent freezing in the winter and to prevent rust the rest of the time. The water/antifreeze is pumped through the engine then when the water is hot it is pumped through the radiator where it is cooled and pumped back through the engine.
It simply heats the engine block. So things like oil don't thicken due to cold weather.
