How can I tell if I need to add coolant to my radiator?
How can I tell if I need to add coolant to my radiator?
Check the freezing and boiling point of your coolant. Over time, the ability of your radiator fluid to absorb and dissipate heat declines. You test the freezing and boiling points with an antifreeze hydrometer. See the directions under “Checking the Coolant Protection Level.” Add coolant as needed.
What should I do if my radiator fluid level is low?
If the level is low, pour the antifreeze directly into the tank, not the radiator. If your vehicle doesn’t have an overflow tank, remove the radiator cap and check the fluid levels to see if you need to add any antifreeze.
What do you put in the overflow tank of a radiator?
If the fluid is not at the top of the opening, fill the empty space with 1 part antifreeze and 1 part distilled water. For cars with an overflow tank next to the radiator, add the coolant through the cap in the overflow tank, instead of directly into the radiator.
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

Do you leave the engine running to check radiator fluid?
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 your radiator fluid is milky?
Drain and replace the fluid if it looks milky. The antifreeze should be slightly transparent and should be the original color of the fluid when you added it to the radiator. Milky or cloudy fluid is a sign that the fluid has been contaminated with oil, which indicates a serious problem with your engine.
