Yes, because water pumps have what is known as a 'weep hole', which will leak coolant when the water pump is going bad. Look for water or moisture in the area of the pump, especially when the engine has reached operating temperature, and then has been shut down. This is the time of the highest pressure in the cooling systen, when the coolant is still absorbing heat, but is not being circulated.
when your engine is hot it causes the water to boil and the water and the anti freeze will come out of the overflow pipe.
if your water/antifreeze gets to hot it pushes out the over flow tube into the overflow container, as it cools down it will suck it out of the overflow and back into the radiator.
Antifreeze is added to a 2005 Honda Civic at the coolant overflow tank. Antifreeze is added at a ratio of 50/50 with water for optimal cooling.
Could be water or antifreeze getting into the oil
1/2 distilled water 1/2 antifreeze to the full line in the overflow container.
A mixture of 1/2 distilled water 1/2 antifreeze to the full line of the radiator overflow container.
Never add water, add coolant, which is a 50/50 mix of antifreeze and distilled water. Add it to the overflow or recovery reservoir.
First thing would be to check if you have enough and correct water/Antifreeze mix in the overflow tank.
Yes, antifreeze can leak from a water pump gasket.
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.
Could be thermostat not opening causing a back pressure
ITS 10.5QT...make it a 50/50 mixture. so take half of that amount as your water and the other half your antifreeze and your all set .you can add a little to your overflow also
