Question

Accepted Answer

130°C Both work well - choose by temperature and coolant loss prioritiesSilicone tolerates much higher temperatures, while EPDM hoses show a lower coolant evaporation rate for better cooling efficiency.EPDM vs silicone at a glancePropertyEPDM hoseSilicone hoseMax temperatureAbout -40°C—150°C  Up to 200°C (392°F);
