Quizplus · Accepted Answer

Technician A is correct because diesel engines with water manifolds have a more uniform distribution of coolant, leading to more even cylinder temperatures. Technician B's statement is incorrect; typically, cylinders closer to the radiator would run cooler due to closer access to the cooled coolant.
