Morphology
The compound 'water pump' is directly and literally built from 'water' (the liquid) + 'pump' (a machine that moves fluids), so its meaning as a device that pumps or circulates water/coolant is immediately inferable. This noun+noun composition is cross-linguistically common and follows a transparent compounding pattern, so a B1 learner who knows both constituents will understand it.
Etymology
Water pump is a very literal name: it's a pump that moves water or coolant through a car's engine like a heart, so the engine stays cool. That's why it means the device that circulates coolant to 'prevent overheating'.
