During the engine operation, fuel constantly burns in order to turn the chemical energy into mechanical energy. In the combustion process, only about 30 percent mechanical power is produced and the remaining amount of energy is converted to heat. Since, constant exposure to extreme heat or low temperature can damage the engine system, standard temperature level is required and the heat generated in its operation should be dissipated. This then accounts to the purpose of cooling system’s engineering, to keep engine temperature in the desired level for efficient performance.

Instead of air cooled systems, vehicles in the modern era carry liquid cooling systems. Apparently cooling systems of Pontiac Torrent, Solstice, G6, Grand Prix Montana, Vibe, GTO, Grand Am, Aztek, Pursuit and others are liquid based. The air cooled system is driven by a powerful fan blowing cold air over a heat conductor that covers the engine block. These are aluminum fins that absorb heat from the cylinders.

On the other hand, the liquid based cooling system lets the fluid circulate through pipes and chambers and absorb heat from the engine. After it leaves the powertrain, the fluid goes through a heat exchanger which we call radiator. In this stage, the radiator fan blows cold air to transfer heat from the fluid to the air. The liquid or coolant that initially absorbs heat from the engine was the result of an improved cooling system, but basically air still plays important role in constantly keeping the engine temperature in the desired level.

The construction of liquid cooling system in a Pontiac includes a Pontiac coolant tank. This is the device that holds the coolant or the chemical solution which is composed of mixture of water and anti-freeze usually of ethylene glycol and anti-corrosion chemicals. With the importance of this compound in the effective operation of the cooling system, the coolant tank is also valued. By its use, enough amount of coolant is stocked in the system for the regulation of temperature level circulating in the engine system and preventing trouble caused by overheating. In some Pontiac models running these days, coolant expansion or fill tanks are incorporated. This is because the coolants expand as it absorbs heat, much like with most liquids. This gives way for additional space for the heated coolant to stay before it is directed unto the radiator.

The coolant tank of your Pontiac could have been damaged due to the pain of constant temperature change or of unexpected situation. Replace problematic Pontiac coolant tank with durable aftermarket Pontiac coolant tank. Here in Parts Train you are assured of the products quality. Choose from the store’s wide selection of Pontiac coolant tanks and other auto parts as well as accessories you need.
