Radiator Reservoir Tank in alluminium

Engine Oil coolant cavitatation occurs during higher than normal Engine RPM under sports driving.
Cavitation cause unstable cooling system pressure and leads to overheating.
Cavitation may also cause serious damage such as cavitation damage (erosion of cooling system).
Reservoir tank prevents from cavitation to occur and thus avoid problems.
It maintains high radiator efficiency and control cooling system pressure by removing cavitation. As a result it regulates temperature from rising.
