Does my coolant reservoir need to be full?
The coolant reservoir is a vital component of the cooling system.
Its function is to store excess coolant fluid until required.
While the engine is off, your coolant reservoir should be about 30% full.
The most common reason for a vehicle to overheat is a leak in the coolant reservoir or one of the attached hoses..
How long can you run an engine without coolant?
