The beginning of winter has passed, and a cold wave has swept in, causing temperatures in Jiangsu to drop sharply and bringing “winter in a second.” Cold conditions pose many challenges to diesel generator operation. Inadequate maintenance can easily lead to starting difficulties, cracked radiators, blocked fuel lines, and other failures. To ensure stable and reliable generator operation throughout the winter, prepare in advance by following these winter maintenance tips.

1. Replace the coolant with one suitable for low temperatures

Some users use purified water or regular antifreeze in summer. Before winter, be sure to replace it with coolant suited to the ambient temperature. We recommend choosing a product with a freezing point 5~10℃ below the local minimum temperature, which effectively prevents low temperatures from cracking the radiator or damaging the engine block.

2. Change to winter-grade engine oil

Winter-grade engine oil differs significantly from summer-grade oil in its ability to withstand low temperatures, and the two should not be mixed. Change to the appropriate winter-grade oil before winter to maintain oil flow at low temperatures and reduce wear during startup.

3. Use diesel fuel with a low-temperature grade

As temperatures fall, regular diesel fuel can release wax, causing wax buildup in fuel lines and blocking the pipes. Switch to diesel fuel with a low-temperature grade in winter to ensure an uninterrupted fuel supply.

4. Carry out dedicated battery checks and maintenance

Batteries are significantly affected by low temperatures. For every 10℃ drop in ambient temperature, battery capacity decreases by approximately 10%. In winter, check the battery charge regularly and keep it fully charged. If the voltage is insufficient, recharge or replace the battery promptly.

Carrying out the above maintenance in advance can significantly reduce the likelihood of generator failures in winter and ensure a stable emergency power supply.
