It is usually best to add the correct mix of antifreeze and water (usually 50/50). In a situation where there is no antifreeze available, yes, add water, then check the coolant later to see if the mix is adequate, and adjust the mix if necessary.
Never add water, add coolant, which is a 50/50 mix of antifreeze and distilled water. Add it to the overflow or recovery reservoir.
There is a reservoir container marked "coolant" in the engine compartment. Add a mixture of 50% antifreeze and 50% water. (If you use "50/50" or "pre mixed" antifreeze, DO NOT ADD WATER). Let the engine get warm and fill to the full line.
add 50/50 mix of coolant and antifreeze or buy premixed from local auto parts supplier
Yes. Never add pure antifreeze. Pure antifreeze will actually freeze before a 50/50 mix. Add coolant that is a 50/50 mix of antifreeze and distilled water. You can buy it already pre-mixed.
If the vehicle is cold yes but make sure you mix the antifreeze with water before you add it, 50-50 is the best mix.
The best reason to use water as a coolant is because is because it has a high specific heat capacity. However, you can add a mix of antifreeze with your water.
a 50/50 mix of good quality antifreeze and water
You can check the coolant reservoir when the engine is cold, if the coolant level is below the add line top it off with the proper coolant, not just water. It is not a good idea to add just plain water. You should use at least a 50/50 mix of water and antifreeze.
for an S series from empty it is about 7 qts. 50/50 water/coolant.
coolant is a mixture of antifreeze and water (usually 50/50) If you were to use just water, you would not have either freeze protection or overheat protection. Water freezes at 32 degrees. Antifreeze could protect engine to -20 to -30 degrees. Water (with no pressure) will boil at 212 degrees. Antifreeze will delay "boil-over" to a much higher temperature (I am not sure of number)
add to coolant recovery tank!!!
