Full Answer

Ensure that the car is in park and the engine is cool before opening the reservoir. If the engine is hot, the pressure from the system could cause hot coolant to spray out. Car owners can purchase concentrated coolant and mix it with distilled water or purchase premixed coolant. Premixed coolant is often more expensive, but it is less messy and more convenient to use, especially for a quick topping off.

  • Q:

    Will a bad radiator cap cause overheating?

    A:

    A defective radiator cap can cause an engine to overheat because the faulty part reduces the functional efficiency of the radiator. The coolant-system temperature is lowered in the radiator by passing through a series of fins and tubes, so anything that disrupts this process decreases cooling, which can lead to an increase in engine temperature.

  • Q:

    What happens if you put too much coolant in a car?

    A:

    The buildup of pressure caused by adding too much coolant to a car can cause the rupturing of hoses, internal pipes and even the radiator. When coolant is added to a car, it is cold, however, while the engine is running, the liquid starts to expand, causing a buildup of pressure. If the radiator is too full, this buildup of pressure is often too great for the internal workings of the car.

  • Q:

    What does low coolant mean on a car?

    A:

    A "low coolant" warning on a vehicle usually means that the vehicle is low on the cooling fluid inside the systems that prevent overheating of the engine. The coolant level can be verified by checking the coolant backup tank under the hood once the engine is cool.
