No. Let it cool down before you open the radiator cap and then put water in the radiator
On older cars / trucks that do not have a coolant recovery tank you should fill the radiator to approximately one inch below the opening. ( when the engine is COLD } On more modern cars / trucks that have a coolant recovery tank, the radiator should be completely filled and the recovery tank should be filled to the full cold mark. You should only do this when the engine is cold to avoid personal injury. Why is the cooling system low? A pressure test should be performed and all leaks repaired.
A water cooler is a system that is designed to keep water cold for some use. This is done usually through an air cooling radiator system. These water coolers are normally used in cars.
It should be a cold temperature.
Why is the second paragraph a contradiction of the first? If hot water pipes 'Absolutely' do not freeze faster than cold water pipes then why the comment about the cold water pipes having a larger diameter which causes them to freeze at a slower rate than the smaller hot water pipes? Also, the word then in the last line should be thanand there should be an a between usually and larger. And, piping should be changed to pipe.
Cold water has a higher density than that of warm water (hence it is lower than the warmer parts of water in the same container). Due to its increased density, the same sinking object will descend more slowly through its warmer comparison.A2. The last part should read ".. than through its warmer .."And in this type of question, you should consider viscosity as well. not much different in hot or cold water, but very different in oil or treacle with temperature change.
Have you checked your thermostat?
the overflow reservoir, it should have marks for full cold and hot
I would suspect the thermostat is the culprit. Replace the thermostat. definately replace the thermostat, get a new gasket and all. Also, start the car cold and see if the inlet hose to the radiator warms up evenly. if it gets really hot on the engine side of the hose and is still cool by the radiator that means that there is no flow and either the thermo is installed wrong or something is clogged
When a car is hot, keep the car running and add water to the radiator. When a car is cold, you can simply put the water into the radiator.
Most definitely.
When the engine is cold it should be up to the cold fill mark
On a 2000 Ford Ranger : With the engine cold the radiator should be filled to the seat for the radiator cap and the engine coolant reservoir should be filled to the cold mark
In the plastic jug on the left firwall be sure to fill it to the "COLD" line if the engine is cold which it should be or you would not have opened the cap.
If the engine is cold... it could mean that the radiator cap is too weak to hold and you need to get a new one. If the engine is HOT... it could mean that you have overheated it and you need to add water after the engine has cooled a bit, to prevent getting burned, be careful and use a towel to remove the cap to add coolant.
If you mean the water in your radiator, don't drive your vehicle until it thaws or your engine will overheat because no coolant will be flowing through it. You should keep 50% antifreeze and 50% distilled water in your car radiator at all times. (maybe slightly more antifreeze in cold winter weather) Water in the radiator won't freeze with antifreeze mixed with it.
there should be a pitcock on bottom of radiator to drain it. or take the bottom radiator hose with motor cold of course .
Maybe a bad head gasket. When cold, take the radiator cap off and start the engine. If it is a head gasket, water should shoot out of the radiator.
