The coolness factor in a Volvo Radiator
Crucial to the flat out performance of a Volvo vehicle is its cooling system. Not only does it manages the temperature level of the engine, it also prevent engine overheating. In result, efficient engine combustion is at its finest. Showcasing a powerhouse cast of components that function up to specs are the water pump, thermostat, transmission cooling lines and the radiator hose. But the one component where the vehicle relies to in order to fend off overheating is the Volvo Radiator. It is some sort of a heat exchanger that transfers thermal energy (heat) from water running from the engine into a cooler one once it passes through the radiator. It then protects the engine from overheating as its temperature is lowered and maintained at bay. As it is connected to the channels running through the engine and the cylinder head, the water passes through a closed system (water pump) to the engine, where it gathers heat away from the engine parts and then transports this heat to the radiator. The Volvo Radiator is installed behind the grille so the cool air outside can pass through the radiator especially when the car is in motion. It is constructed with two main parts namely: a core made up of small flat tubes, and overflow tanks that are either on the top and bottom of the core or on either side. As the hot water enters through the confines of the top tank in the radiator, it is being filtered down then cooled via the radiator fins. After which it goes back to the engine through the water pump. The radiator transfers this heat to the air. A system of valves that baffle to also operate a smaller radiator called heater coil is used to warm the interior cabin with the gathered by the coolant. Tough-made as they are, Volvo Radiator encounters the rough wear and tear. As it ages, it could become prone to defectiveness or damage. Salt from ocean air, road salt, debris and other chemicals break down the metal in an auto radiator core. All these factors can contribute to an overheating vehicle, which could potentially cause a blown engine.
