Turn the radiator cap anticlockwise to relieve any pressure in the cooling system.
Push down and turn the radiator cap anticlockwise to remove it.
The coolant level should be up to the base of the filler neck.
Put the radiator cap back on, and tighten it fully.
How do I know where to put water in my car?
Where do I put water when my car overheats? You need to put the water in the radiator by removing the pressure cap once your vehicle cools down. You can also add the water to the coolant reservoir or recovery tank if your car is overheating to the point where there’s steam.
Can I just add water to my car?
Running just water in your car’s radiator will guarantee overheating and damage, including to your cylinder heads and engine block. And most tap water contains minerals that will leave deposits inside the radiator, causing corrosion, shortening its life and further diminishing its ability to cool.

Only Use Water In The Radiator In An Emergency
If you notice that your engine temperature is rising, you should pull over immediately. Allow the engine to cool and check the coolant overflow reservoir level. If it’s really low or actually empty, you need to add fluid to your vehicle.
Does every car need water?
Cars don’t specifically need water to run properly. Water is part of coolant, which is needed, but water on its own should not be used unless there’s an emergency and your car is overheating. Coolant uses a mixture of water and additives that change the boiling point and freezing point of the water.
What happens if you use water instead of coolant?
If you were to just use water rather than the coolant mixture, high temperatures inside the motor would easily boil that water and cause it to evaporate, meaning you’d quickly have no coolant at all and the engine would easily overheat.
Can you use just water for coolant?
Water by itself can’t do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle’s engine. Plus, it doesn’t absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.
Can a car run on water instead of coolant?
A car will not overheat if you use water instead of coolant, but it is not recommended to use water as a coolant because it can freeze and cause serious damage to your engine. Antifreeze has a lower boiling point than water, so it stops water from overheating in high temperatures.
Can you top your coolant up with water? Coolant should only be topped up with water in case of an emergency when the coolant liquid level is lower than it should be. While topping up with water will help you get safely to the nearest garage and identify any issues, it shouldn’t be relied upon.
How do I know if my car needs coolant?
5 Signs That Your Vehicle Needs An Antifreeze/Coolant Service
The temperature gauge reads hotter than normal when the engine is running.
Antifreeze leaks and puddles beneath your vehicle (orange or green fluid)
A grinding noise is coming from under the hood of your car.
What happens if I put too much water in my car?
Most of the time, excess coolant is expelled from an overflow hose. You’ll likely see a puddle of coolant beneath your car if this has happened. In worst case scenarios, overfilling your antifreeze tank can lead to electrical damage if overflow comes into contact with engine wiring.
What happens if coolant is low?
Coolant helps pull heat away from the engine. So, without enough coolant, the engine could overheat or seize up. Continued use of an overheated engine could lead to permanent damage, such as pistons welding to the cylinders.
How long can you drive a car without coolant?
But if you start the engine without coolant in an environment where temperatures are low, then it is guaranteed that it will be able to drive no more than 500-1500 meters without consequences. What is this? Liquid-cooled motors must not be operated with a faulty cooling system, even in winter.
This deteriorated liquid can trigger severe harm to your engine by failing to control the temperature. Therefore, manufacturers suggest replacing the coolant periodically. It is recommended you change coolant after the first 210,000 km (140,000 miles) or 120 months, then every 30,000 km (20,000 miles) or 24 months.
Will engine light come on if coolant is low?
If the level falls below a critical amount of coolant in the radiator or expansion tank (attached to the radiator via a hose or pipe), the sensor sends a signal to the vehicle’s onboard monitoring system which then turns on the low coolant warning light on the instrument panel in order to alert you of the issue.
How often should I top up my coolant?
Antifreeze should be replaced every 3-5 years depending on how often and how far you drive your car, its age, and the temperature of where you usually drive. Extra care needs to be taken in the summer months, especially if it’s a hot day, so make sure you check your coolant levels before the start of the summer.
How often should you add coolant?
On average, most automobile manufacturers recommend a coolant flush every 30,000 miles or two years, whichever comes first.
How far can you drive with water in radiator?
In general terms, if you HAVE to drive a car that’s lost it’s coolant, you can replace it with ordinary tap water or even water from a ditch or stream in an emergency, so as to travel a few miles, even a hundred miles, so long as it’s above freezing.
How do I fill my car radiator with water?
The 5 Steps to Fill Water in Car Radiator
Step 1: Pay attention while opening the radiator cap.
Step 2: Check the water level before filling.
Step 3: Turn on your car engine.
Step 4: Mix water with antifreeze, if necessary.
Step 5: Fill water in the car radiator and tighten the cap.
