At the time, warming the car in the winter made sense since it could take several minutes for the right air-fuel mix to reach the engine, without which the vehicle was at risk of stalling or ...

Core plugs can also sometimes prevent freeze damage to the motor. During the early stages of the freezing of the engine coolant a freeze plug will sometimes burst or pop out, and thus allow the coolant to exit the engine, before it might expand within the engine during the freezing process and potentially crack the engine block.

Engine oil heater attached to the engine's oil pan with magnets. Engine oil heater inserted into the dipstick tube. In-line coolant heaters, which are installed into a radiator hose to warm the coolant (sometimes with a circulation pump to increase its effectiveness). Electric blankets that are laid over the top of the engine.
Engine cooling removes energy fast enough to keep temperatures low so the engine can survive. [2] Some high-efficiency engines run without explicit cooling and with only incidental heat loss, a design called adiabatic. Such engines can achieve high efficiency but compromise power output, duty cycle, engine weight, durability, and emissions.
Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There ...
For newly introduced models, the regulation dates applied a year earlier – January 1, 2000 for petrol and January 1, 2003, for diesel. For passenger cars with a Gross Vehicle Weight rating of greater than 2500 kg and for light commercial vehicles, the regulation dates applied from January 1, 2002, for petrol models, and January 1, 2007, for ...
The 400 was made in 4-bolt main journal from 1970 to 1972 and in 2-bolt main journal from 1973 to 1979. The 400 can have either 2 or 3 frost-plugs per side though all 400 blocks have the provisions for a 3rd frost-plug on each side. The 400 was rated at 245–265 hp (183–198 kW) gross (150–180 hp (112–134 kW) SAE net) through its life ...
