How to determine the front end of an engine?
The front end is opposite to the back end, and the front end has generator, water pump, air conditioner, compressor, fan and so on. The belt is connected with many belts, so many pulleys can be seen.
You mean the end of the engine is the front, is that the back end? The rear end of the general engine flywheel is the power output, and the back is the shock absorber, torque converter, gearbox and so on.
