How does the radiator allow the cooling system to build up pressure?
When the fluid in the cooling system heats up, it expands, causing the pressure to build up. When the radiator cools back down, a vacuum is created in the cooling system that pulls open another spring loaded valve, sucking water back in from the bottom of the overflow tank to replace the water that was expelled.
Why is there too much pressure in my radiator?
The coolant continually running from your radiator to your hot, running engine and back again creates a lot of pressure. That pressure buildup will eventually spell doom for your radiator hoses. If your radiator is too corroded, this can cause a leak in the body of your radiator even if the hoses are intact.
Why does a coolant flow radiator slow down an engine?
If the air coming through the radiator is cool, the opposite happens; the coil spring contracts, the oil leaves the fluid coupling and the fan slows. Slowing the fan when it is not needed reduces fuel consumption, makes less noise and saves engine power.
Where is the coolant flow radiator located on a car?
The Heater Core The heater core is a smaller version of the radiator that is used to keep your toes warm when it’s cold outside. The heater core is mounted under the dash board. Some of the hot coolant is routed through this little radiator, by more hoses.
What should the running temperature of the radiator be?
When the thermostat is closed, it prevents coolant from leaving the engine and circulating through the radiator until the correct running temperature is reached. The correct running temperature for most engines is between 180 degrees F and 200 degrees F.
Why does the lower radiator not need an anti-collapse spring?
Because the lower radiator hose channels coolant to the water pump and engine, it is susceptible to negative pressure and collapse at high rpm. The anti-collapse spring prevents that from happening. One hose manufacturer says you don’t need the anti-collapse spring because it was used only for factory-fill purposes.
