Question

In liquid cooling, the liquid becomes heated in its passage through the jackets and is itself cooled by means of an air-cooled radiator system.

(a) True

(b) False

The question was asked during an interview.

This key question is from Liquid Cooling Systems in portion Heat Rejection and Cooling of IC Engine

Answer 1

The correct answer is:

(a) True

In liquid cooling systems, the coolant absorbs heat as it passes through the engine's jackets. Afterward, the heated coolant is circulated to an air-cooled radiator system, where the heat is dissipated into the surrounding air, cooling the liquid before it returns to the engine. This process helps maintain optimal engine temperature.
