How does a thermostatically controlled cooling system work?

How does a thermostatically controlled cooling system work?

When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions.

How does a mechanical car thermostat work?

The thermostat is basically a valve between the engine and the radiator. When the coolant in the engine gets too hot, this valve opens, letting it pass to the radiator where it will cool down. If it is not heated, the thermostat stays closed, allowing the coolant to continue circulating inside the block.

Is thermostat and coolant the same?

Nope they are not the same thing. The thermostat simply lets water flow and is thermally controlled.

What does an engine thermostat do?

The thermostat is like a valve that opens and closes as a function of its temperature. The thermostat isolates the engine from the radiator until it has reached a certain minimum temperature. Without a thermostat, the engine would always lose heat to the radiator and take longer to warm up.

What happens if thermostat is stuck closed?

If the thermostat becomes stuck in the closed position, the circulation of the coolant is blocked so the coolant cannot get to the radiator to be cooled which causes the engine to overheat.

What is the best temperature for a car thermostat?

between 195 degrees and 220 degrees
Most experts agree that your engine should run between 195 degrees and 220 degrees. In ideal situations, your needle will maintain a posture right in the middle of your gauge.

Can a car work without a thermostat?

You can drive without a thermostat for short periods of time. Without the thermostat in place, your engine won’t work at the required temperature range. This action causes the engine to malfunction and affects the overall performance of your car. This can also cause your engine to take a longer time to warm up.

Should I use a 180 degree thermostat?

A 180 degree thermostat is just a help for other engine mods. By itself, it will do nothing to increase your performance. The SRT engineers do not recommend replacing your factory thermostat (probably for emission purposes).

How do you unstick a thermostat?

To fix a thermostat that if stuck open you will:

1. Park your car on a flat surface and allow the engine to cool.
2. Locate the thermostat.
3. Remove the radiator cap.
4. Disconnect the radiator hoses from the engine.
5. Replace the valves in the thermostat hoses.
6. Top off antifreeze fluid levels.
