Abstract
This specification covers the requirements of a stop-leak additive to function effectively in automobile and light duty service. The stop-leak is intended to seal small leaks in engine cooling systems without adversely affecting heat transfer and fluid flow. The hole plugging capability, and foaming tendency of the stop-leak additive shall be tested to meet the requirements prescribed.
