Expansion Tanks (coolant tank,radiator expansion tank)
What they do?
An expansion tank is used in the cooling system of most internal combustion engines, to allow the coolant, the antifreeze, and the air in the system to expand with rising temperature and pressure. The tank is also called a "coolant recovery tank", since it prevents venting and permanent loss of coolant, by allowing it to be sucked back into the cooling system as the engine cools.
Failure Symptoms

---Coolant leaks. Another symptom of a faulty intake manifold gasket is coolant leaks. ... ?
---Engine overheating.
