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. |
