usually once the cap has been put back on and the engine has reached operating temperature and cooled down again it would have expelled any excess water from the cooling system and left behind the appropriate level of water. always recheck level in case a large bubble of air was expelled and left the water level too low.
There is a water reservoir tank that goes to the radiator that you can add the water to.
To add water to the radiator on a new beetle, first remove the lower radiator hose. Then add water to the coolant reservoir.
When a car is hot, keep the car running and add water to the radiator. When a car is cold, you can simply put the water into the radiator.
You can add water to a radiator any time it is low on water.
Look for a radiator cap and add it there.Look for a radiator cap and add it there.
first turn on the car and add the water to the radiator while the engine is running-- this allows the water pump to work and force the water to all the thirsty parts this will help the radiator and the crankcase fill much faster
It is better to add premixed anti-freeze.
It is no longer necessary to add just water to a radiator in newer cars like the 2005 Malibu. An antifreeze that is half water and half antifreeze is usually best. Add the 50/50 antifreeze to the radiator overflow tank. It should be a plastic, see through tank hooked to the radiator.
If you are speaking of a radiator in an automobile, there is a plastic bottle on the side of the radiator, and it is marked for the fluid level; "ADD" or "FULL". The cap on the bottle will say "COOLANT ONLY" or words to that effect. Do not overfill. Older model vehicles you will add water to the radiator itself. Remove the radiator cap, slowly, and pour in the water. NEVER REMOVE THE RADIATOR CAP IF THE ENGINE HAS BEEN RUNNING! Wait until it cools down.
At the radiator or overflow tank. Do not add water, add coolant.
fill the radiator to the top with 50/50 water and antafrezz
I have a 92 Ford F150 and the cap is on top of the radator, but you can also add water via your overflow since your over flow is up higher, it will still drain into your radiator.
