Siting, the Coolant Reservoir is an important component which is installed in Buick Regal automobiles and has the function in the engine cooling system to solve the problems on the excess coolant fluid, the entrance of air into the cooling chamber, and the spillage of the coolant. This reservoir is usually a plastic tank mounted on the radiator having marks which are used to indicate the level of the coolant; this should be done while the engine is cold. Buick Regal models have utilized two primary types of Coolant Reservoirs: we have the pressurized and the non pressurized types. The pressurized system contains a metal cap labelled for pressure and the non-pressurized system contains the basic round plastic cap. The pressurized reservoir is structurally different from the non-pressurized reservoir and works at higher temperatures and pressures and thus facilitates the expansion and contraction of the coolant while in the non-pressurized system gravity is used to control coolant flow. Daily or weekly checking of Coolant Reservoir for crack or leakage is advisable to avail its premier efficiency and avoid contamination.
