Is it OK to add water to coolant?
While it’s ideal to add a 50/50 mix of coolant and water (or a pre-mixed coolant), if you absolutely have to keep driving, you can add water to the radiator to get you to your destination. If you attempt to remove the cap while it is still hot, hot coolant can sputter and may cause burns.
How does the cooling system work on a Honda Civic?
A Honda Civic’s cooling system is a sealed system, meaning that it uses pressure to raise the boiling point of the fluid within the radiator. As the engine operates, the fluid within the radiator circulates throughout the engine.
Why is water boiling out of radiator in Honda Civic?
When it is sitting idle and the temperature is in normal operating range, the water is contsantly boiling out. We have bled the system as directed but no luck. When you step on the gas peddle the water will shoot out of the radiator with the cap off. The top hose is hot, the bottom is cool but does not feel like there is any pressure.
Do you mix coolant and water with radiator fluid?
To mix the radiator fluid properly, mix the coolant and distilled water in a 50/50 proportion. Fill an empty radiator fluid bottle halfway with water and then fill the rest of the bottle with radiator fluid.
When to replace radiator cap on Honda Civic?
A radiator cap’s rating varies on the size of the radiator. As Honda does not use the same radiator in all of its Civics, its caps differ. The pressuring rating will be stamped into the cap. If the cap releases the pressure early, replace the radiator cap.

Why is my Honda Civic not cooling properly?
In cases like that the coolant is no longer cooled mostly by airflow through the radiator. When you stop the temperature spikes and the thermostatically controlled electric cooling fan starts…and runs until temps. are brought below the lower limit of the sensor that controls on/off of that fan.

Where does the radiator fluid go when it gets hot?
Besides the radiator tank, most modern cars have an overflow tank for the radiator fluid to expand into when it gets hot. You should normally find little fluid in here, if any. If your coolant level is low in the radiator and nearly full in the overflow tank long after the car has been driven, take the car in for servicing at once. 7
