The radiator is responsible for tranferring heat from the coolant to the outside air. Radiator hoses transfer coolant to and from the engine to the radiator and a radiator cap maintains pressure in the cooling system to increase the boiling point of the coolant mixture and thus allow it to absorb more heat.
Which of the following maintains pressure in the cooling system?
radiator cap |
|
water jacket |
|
water pump |
|
thermostat |
