It is possible for radiator fan to spin in a wrong direction due to placement or connection. This can cause engine overheating and also waste energy. It is sometimes difficult to track this fault since the fan still rotates.
Most sensors and actuators in cars are electrically powered. A loss of power or low voltage supply to these components can impede their function and throw the vehicle into limp mode.
The headlight flasher of a car is designed in such a way that multiple flashes can be done in very quick successions. The lights can be flashed or held ON.
Radiator fan speed is normally controlled by the ECU or fan control module. If the system is bypassed, it has negative side effects like high fuel consumption, shortened fan lifespan.
Emission of black smoke from exhaust of a vehicle has many possible causes. It is due to faults that cause incomplete fuel combustion as a result of rich air-fuel mixture.
Overspeeding has negative safety and economic effects. Also, in trying to beat time by speeding excessively, the driver might end up having more travel time.
Some vehicles have transmission oil temperature guage. For others that do not have, a scantool that plugs into obd2 port or a handheld infrared thermometer can be used.
Transmission fluids expand as they heat up. This changes the volume and consequently the fill level. This makes the temperature st which fluid level is checked important.
