Engine fan with viscous drive. A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.
Once at optimum temperature, the thermostat controls the flow of engine coolant to the radiator so that the engine continues to operate at optimum temperature. Under peak load conditions, such as driving slowly up a steep hill whilst heavily laden on a hot day, the thermostat will be approaching fully open because the engine will be producing ...
The Ram pickup (marketed as the Dodge Ram until 2010 when Ram Trucks was spun-off from Dodge) is a full-size pickup truck manufactured by Stellantis North America (formerly Chrysler Group LLC and FCA US LLC) and marketed from 2010 onwards under the Ram Trucks brand. The current fifth-generation Ram debuted at the 2018 North American ...
Block heater. Electrical cord for powering a block heater. A block heater is used in cold climates to warm an engine prior to starting. They are mostly used for car engines; however, they have also been used in aircraft engines. The most common design of block heater is an electrical heating element embedded in the engine block .
However, once water boils, it is an insulator, leading to a sudden loss of cooling where steam bubbles form. Steam may return to water as it mixes with other coolant, so an engine temperature gauge can indicate an acceptable temperature even though local temperatures are high enough that damage is being done. An engine needs different temperatures.
Dodge Durango. The Dodge Ramcharger is a large sport utility vehicle built by Dodge from 1974 to 1993, based on a shortened-wheelbase version of the Dodge D series / Ram pickup chassis. A Plymouth version, named the Plymouth Trail Duster, offered from 1974 to 1981, was Plymouth's only SUV. The Ramcharger was mostly produced as a two-door, 4×4 ...
In current automotive terminology it typically refers to a hard or soft cover that spans the back of a pickup truck to protect the load from weather elements or thieves, or to improve aerodynamics. Tonneau covers come in many styles that fold, retract, or tilt open, and can be locked shut. Common materials used include steel, aluminium, canvas ...
Antifreeze. An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [ 1] However, all common antifreeze additives also have ...
