проверьте 5 вещей в каждой машине, прежде чем менять охлаждающую жидкость

Hi, I am Saourav Kumar from #INDIA #CheckBeforeChangingCoolant
इस वीडियो में, मैं आपको कूलेंट बदलने से पहले जांच करने के लिए 5 चीजों के बारे में बताने जा रहा हूं ताकि ओवरहीटिंग नहीं हो.
in this video, I am going to tell you about 5 points to check before changing the coolant in your car so that overheating will not occur in your car

The thermostat in most cars is about 2 inches (5 cm) in diameter. Its job is to block the flow of coolant to the radiator until the engine has warmed up. When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature (generally about 200 degrees F, 85 to 95 degrees C), the thermostat opens. By letting the engine warm-up as quickly as possible, the thermostat reduces engine wear, deposits, and emissions.

The secret of the thermostat lies in the small cylinder located on the engine-side of the device. This cylinder is filled with a wax that begins to melt at perhaps 180 degrees F (different thermostats open at different temperatures, but 180 F/82 C is a common temperature). A rod connected to the valve presses into this wax. When the wax melts, it expands significantly and pushes the rod out of the cylinder, opening the valve. The wax happens to expand a good bit more because it is changing from a solid to a liquid in addition to expanding from the heat.

1. Turn On The Heater
It sounds counterintuitive, but Reina recommends turning on the heater. It draws warmth away from the engine and into the passenger compartment, lessening the burden on the engine’s cooling system. In certain circumstances, that may be enough to reverse the overheating, he says. You’ll know it’s working if the warning light goes off or the temperature gauge returns to the neutral position.

2. Pull Over
If your car continues to overheat after you’ve been driving for a few minutes with the heater on, pull over and cut the engine off—it’s the safest and surest way to cool the engine, says Reina. If you have roadside assistance, now is a good time to call, as you may need a tow, Reina suggests.

3. Be Patient
If you don’t have roadside assistance, be patient; it will take at least 15 minutes for the engine to cool. In the meantime, do not attempt to open the hood; the coolant in a car that has overheated may be in excess of 230 degrees, says Reina. Once the hood is open, there’s a risk of being sprayed with hot water or steam. “Your personal safety is most important,” he says. “Waiting for at least 15 minutes allows the hood, engine, and leaking coolant to cool.”

4. Add Coolant
adding coolant after 5000km about 200ml is ok if more than 350ml akes then there will b some leakage internal or maybe external.

5. Drive To A Service Station
Adding coolant does nothing to address the problem that caused your engine to overheat.
