Q: I have a 2012 Ford F-150 with 120,000 miles on it. It runs great and I am planning a 5,000-mile trip. I have replaced the tires, brakes and all the vital fluids except coolant. Should I replace ...
Physical activity in extremely hot weather should be avoided. If a person starts to experience over heating, and symptoms of heat syncope, they should move or be moved to a shaded or cool area. It is also recommended to avoid alcoholic beverages in hot weather, because they cause dehydration which may worsen symptoms.
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 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.
A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system.
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]
The most common causes are accidents with grease guns, paint sprayers, and pressure washers, but working on diesel and gasoline engine fuel injection systems as well as pinhole leaks in pressurized hydraulic lines can also cause this injury.
These risky driving behaviors are associated with depression as contributing factors to vehicular suicide. [9] Impact velocity may be maximized by exceeding speed limits or by maneuvering into a head-on collision with a heavier and less maneuverable vehicle like a bus or semi-trailer truck .
