For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and ...
A working system should not generate further trapped gas. Air may be drawn in if there is a small leak, or dissolved air in make-up water may come out of solution, but this generally indicates a system leak if new water is needing to be added. The most likely cause of continual gas bleeding is hydrogen, rather than air. [2]
A system of valves or baffles, or both, is usually incorporated to simultaneously operate a small radiator inside the vehicle. This small radiator, and the associated blower fan, is called the heater core, and serves to warm the cabin interior. Like the radiator, the heater core acts by removing heat from the engine.
This is known as a pre-start engine check. First all the lines and hoses are checked for breaks and leaks. Second the radiator is topped off with water to ensure that the system is sealed off. Next the oil level is replenished. Finally the battery charge is checked and the ignition system is inspected. The engine is then ready to be started. [21]
This causes an incomplete burn which causes the fumes to explode in the exhaust system along with an audible pop or bang sound. This is a result of working equipment, and is unlikely to cause damage. A fuel-injected engine may backfire if an intake leak is present (causing the engine to run lean), or a fuel injection component such as an air ...

While on common perception the engine is the main cause for noise, tire noise becomes the dominant source of noise above 20–30 miles per hour (30–50 km/h) for passenger vehicles. Although aerodynamic noise does increase at highway speeds, it contributes less than tire noise unless at very high speeds. [14]
