Can You Still Drive with Low Engine Coolant?

[Stewart]

It is not advisable to continue driving when the engine coolant level is too low; it should be replenished promptly. The primary function of engine coolant is to maintain the operating engine within a normal temperature range. It cools the engine when it overheats and also provides antifreeze, anticorrosion, and anti-scaling effects. If the engine coolant level is low but still above the minimum mark, with some remaining in the reservoir, you can still drive. Although the coolant level is low, there is still enough coolant circulating in the cooling system, which won't significantly affect engine cooling. However, it should still be replenished as soon as possible. If the coolant level is so low that the reservoir is nearly empty, you must not drive. Continuing to operate the vehicle will cause the engine temperature to rise rapidly without adequate cooling, leading to potential engine damage. Regularly inspect the vehicle's cooling system and the remaining engine coolant level. If the coolant is found to be insufficient, it should be replenished immediately.
