Why is my car overheating even with a new radiator?
A faulty water pump could be why your car is overheating even with a new thermostat. A water pump that is not working properly can lead to overheating because the hot coolant is not being pumped out of the engine and replaced with the cooler fluid that is exiting the radiator.
Why does my car temperature go up when I stop?
If your car begins to overheat when idling, but the temperature gauge moves back down once you get going, it’s most likely due to a broken radiator fan. When the coolant goes to the radiator, it’s spread over a large surface area to cool it down. Airflow further cools it before it returns to the engine.
Can using water instead of coolant cause overheating?
Water isn’t the cause of overheating. Your coolant mixture (of whatever proportion) and radiator work together to get rid of the heat. If it’s not hot, you won’t overheat. However, when it is hot, the coolant can only absorb heat up to its boiling point.
Can you drive with just water in the radiator?
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.
