Understanding the Importance of the Coolant Reservoir

When I first noticed my 2016 Buick Encore’s engine overheating, I realized how vital the coolant reservoir is. This component stores excess coolant and helps maintain the engine’s temperature. Without a properly functioning reservoir, the engine risks damage from overheating or coolant loss.
