Is Radiator Stop Leak Harmful to the Engine?

[LaGenevieve]

Radiator stop leak is safe for short-term emergency use without side effects. However, prolonged use may cause it to dislodge, potentially clogging the radiator and hoses, and may also corrode the radiator. Below are the relevant details: 1. Principle of Radiator Stop Leak: Radiator stop leak has the property of preferentially wetting and adsorbing on technical surfaces or gaps, then solidifying to prevent coolant leakage. The basic principle is to utilize the pressure difference inside and outside the leakage point. During the leakage process, adhesive-carrying particles move into the gaps or cracks and gradually accumulate to fill them. These particles are bonded together by the adhesive, achieving the purpose of stopping the leak. 2. Applicable Situations: Radiator stop leak is suitable for sealing gaps and cracks smaller than 0.8mm. If the leak is severe, the stop leak agent may not be effective, but it can seal minor leaks.
