Antifreeze helps the engine run cooler in the hot months and prevents the coolant from freezing in cold weather.
Yes , mine has a cold and hot mark , the coolant should be up to the cold mark when the engine is cold
The reservoir has two level lines - one for "cold engine" and the other for "hot engine". If the engine is hot, and the coolant level is low, fill the reservoir to the "hot engine" level. When the engine is cold and the level is low, I usually" top off" the radiator and fill the reservoir to the "cold engine" level.
Actually, the heat regulator for the engine is the thermostat. It closes off the coolant when the engine is cold and circulates more coolant when the engine is hot.
when the engine is running and coolant will become hot to its operating temperature,the cooling system is under pressure,coolant will overflow and goes to coolant reservoir.when the engine goes cold coolant will go back to the rediator.
The engine coolant temperature sensor is probably at fault.
The coolant expands and rises when it is hot so it goes up, the coolant comes down when the car is cold.
Try replacing the engine coolant temp sensor.
Off and cooled down. Putting cold coolant into a hot block can crack it. And it can damage the radiator, as well as spitting the coolant back at you.
Adding coolant to a 2003 Pontiac Grand Am is very easy to do. The coolant can be directly added to the radiator. Make sure the engine is not hot before adding the coolant.
Yes. First top up the radiator then fill the overflow reservoir to the "HOT" mark if the engine is hot or the "COLD" mark if the engine is cold. Be CAREFUL when you remove the radiator cap on a hot engine. The coolant is under pressure.....
In a Chevy Lumina, low coolant means that the car needs more anti-freeze/coolant added. This is needed to keep the engine from getting too hot
