An engine needs different temperatures. The inlet including the compressor of a turbo and in the inlet trumpets and the inlet valves need to be as cold as possible. A countercurrent heat exchanger with forced cooling air does the job. The cylinder-walls should not heat up the air before compression, but also not cool down the gas at the combustion.
A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface area for heat transfer to air that is forced past them by a fan, thereby ...
Waterless coolant is most prominently used in the cooling systems for motorsports, classic car, ATVs, UTVs, snowmobiles and older cars. [4] Older cars often have non-pressurized cooling systems, and the water-based coolant can boil and overflow. Traditionally, this issue has been solved by topping off the radiator with water. This dilutes the ...
Once the coolant absorbs the heat from the engine it continues its flow to the radiator. The radiator transfers heat from the coolant to the passing air. Radiators are also used to cool automatic transmission fluids , air conditioner refrigerant , intake air , and sometimes to cool motor oil or power steering fluid .
Combining heating, cooling, and ventilating, the new air conditioning system for the Nash cars was called the "All-Weather Eye". [16] This followed the marketing name of " Weather Eye " for Nash's fresh-air automotive heating and ventilating system that was first used in 1938. [ 15 ]

The most common type of block heater is an electric heating element in the engine block, which is connected through a power cord often routed through the vehicle's grille. Some block heaters are designed to replace one of the engine's core plugs and therefore heat the engine via the coolant. [4] Alternative methods of warming an engine include: [5]
