Does car need to be running to fill radiator?
If you must add liquid to the radiator if the engine is still warm, always do so slowly with the engine running. This way, the cold liquid joins the stream of hot water that’s circulating through the system rather than falling all at once into the system when you start the engine again.
What to do if coolant is coming out of radiator?
Rev up the engine again and loosen the air bleeding valves until there is only flowing coolant from them. Put your radiator cap back. If your coolant temperature is now at 90c (work temperature) and you have heat inside your car, the air should now be gone from your vehicle. Warning: Hot coolant can cause damage to you if it’s not used with care.
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
When is the best time to check the radiator fluid?
You want to check the antifreeze or coolant level while the engine is cool or lukewarm, not hot or cold. If you have driven the car a longer distance, let the engine cool for several hours. Do not leave the engine running when you check the radiator fluid level, and do not ever try to check the radiator fluid level when the engine is hot.
What does it mean when coolant is leaking from Radiator?
A leak means that the stored coolant is dripping out, which will eventually cause a low coolant level. To prevent engine overheat, ensure you check your radiator and coolant level regularly. If you notice your temperature gauge is going high while driving, you have to pull over, turn off your car.

What happens if you don’t put antifreeze in the radiator?
The radiator cools your engine and without it, the engine may overheat and stop working. The radiator needs water and coolant (antifreeze) to function properly. To ensure this, you must check and add coolant periodically in order to maintain an adequate radiator fluid level.
