CATERPILLAR GENERATOR JACKET WATER PRE HEATING PUMP (TROUBLE SHOOTING) REMOVING PUMP & THERMOSTAT

Water jacket heaters and engine pre‑heaters, also known as engine block heaters, are essential for maintaining ideal starting temperatures for diesel and natural gas generators. They keep the engine coolant at 100 to 120 °F to avoid dangerous cold starts. The jacket water heater package is designed to efficiently pre‑heat the G3516C engine by heating and circulating the coolant. Forced coolant circulation allows the system to operate effectively. The video demonstrates dismantling the pre‑heating pump, replacing its thermostat, and resolving an issue where the auto was not stopping.
