Reactor cooling water is potentially contaminated with radioactive elements and you don't want those to be released into the environment, so it is kept in the primary loop.
The description of the symptom could indicatev a head gasket leak allowing the pressure of the combustion chamber to intrude into the cooling system and forcing the coolant out.
AnswerRadiators work by radiating heat into the air and cooling the engine. Coolant flows through the engine block and then to the radiator. The cooling fan helps keep the radiator cool allowing the heat to be put out into the air. This is correct
Pressure test the cooling system, or a leak down test to determine if its a blown head gasket. Combustion gases can leak into the cooling system via a blown headgasket, causing air bubbles, not allowing the coolant to circulate and causing an overheating engine.
Low coolant level, air in the cooling system. Low coolant level or a faulty rad cap allowing air to be sucked into the system when it should be sucking in coolant from the overflow bottle.
Coolant? Bad radiator Radiator has a separate cooling tank (usually at the side or bottom of radiator) for transmission fluid. At times this tank ruptures allowing coolant to get into transmission. Most times causing a transmission failure.
Low coolant? Cooling system airbound? Low coolant? Cooling system airbound?
Several possibilities - from easiest to most expensive: Faulty or inoperable radiator cooling fan - causing overheating. Faulty thermostat - causing overheating. Water pump failure - causing overheating. Blown head gasket - allowing exhaust gasses to escape into the cooling system and expelling the coolant.
Low coolant? Cooling fan not working? Bad thermostat? Cooling system airbound? Water pump not circulating coolant? Radiator core plugged or restricted? Bad radiator cap?
the water pump moves coolant through the entire system. this means the engine, radiator, heater core, and any other hoses or components that require coolant. the radiator is where most heat is transfered into the atmosphere by air flow from the car moving, or an auxilllary fan. the cooling system also contains a thermostat. this is a mechanical object placed at a radiator hose and the engine block. when coolant reaches a certain temperature, a spring on the t-stat causes the valve to open allowing coolant flow to complete.
The coolant will not protect the cooling system against corrosion.
The cooling fan temp sensor detects the coolant is hot and it will remain on until the coolant cools down, usually in a few minutes. Check the coolant reservoir to be sure the coolant is at the proper level. Must be an import.-Normal.
