Core plugs can often be a source of leaks due to corrosion caused by cooling system water. [4] Although modern antifreeze chemicals do not evaporate and may be considered "permanent", anti-corrosion additives gradually deplete and must be replenished via a flush and refill. Automotive manufacturers specify time and mileage numbers for cooling ...
An air-cooled engine uses all of this difference. In contrast, a liquid-cooled engine might dump heat from the engine to a liquid, heating the liquid to 135 °C (water's standard boiling point of 100 °C can be exceeded as the cooling system is both pressurised, and uses a mixture with antifreeze) which is then cooled with 20 °C air.
As the boiling point of water increases with increasing pressure, these pressurised systems could run at a higher temperature without boiling. This increased both the working temperature of the engine, thus its efficiency, and also the heat capacity of the coolant by volume, allowing smaller cooling systems that required less pump power.

A motor vehicle service or tune-up is a series of maintenance procedures carried out at a set time interval or after the vehicle has traveled a certain distance. The service intervals are specified by the vehicle manufacturer in a service schedule and some modern cars display the due date for the next service electronically on the instrument panel.
But home heating systems running for hours can increase the risk of carbon monoxide poisoning as the deadly fumes can be produced by furnaces, stoves and heaters, according to the U.S. Centers for ...

The specific heat of water or water/glycol is about twice that of oil, so a given volume of water may absorb more engine heat than can the same volume of oil. Therefore, water may be a better coolant if an engine is permanently producing large amounts of heat, making it better for high-performance or racing engines.
