Reactor coolant water is kept contained in the primary loop to prevent contamination of the surrounding environment in case of a leak or accident. Mixing it with feed water or allowing it to leave through the cooling tower would increase the risk of radioactive release. Keeping it contained also helps maintain a closed system for efficiency and safety.
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
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.
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? Cooling system airbound? Low coolant? Cooling system airbound?
Low coolant? Cooling fan not working? Bad thermostat? Cooling system airbound? Water pump not circulating coolant? Radiator core plugged or restricted? Bad radiator cap?
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.
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.
To bleed the cooling system on a 2004 VW Bora, first ensure the engine is cool. Open the coolant reservoir cap and start the engine, allowing it to reach operating temperature. With the heater set to maximum, check the coolant level and add coolant as necessary. Once the thermostat opens, air bubbles may escape; continue to run the engine until the bubbles cease, then top off the coolant and replace the cap.
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.
