As engine is produced with foreign technology, basic data for cooling fan are very few in korea. Therefore, an experiment was performed to obtain data on cooling fans for the cooling system. The results obtained are summarized as follows: 1. Efficiency of cooling fan was 49.9% while the engine eras running at the rated power. 2. Shaft power of the fan was 0.5 kW maximum at the rated power. 3. Air flow rate of the fan was $12.9m^3/min$. at the rated power. 4. Static pressure of the fan was 29.8 mmHg at the rated power.
