You can add water to a radiator any time it is low on water.
yes
first turn on the car and add the water to the radiator while the engine is running-- this allows the water pump to work and force the water to all the thirsty parts this will help the radiator and the crankcase fill much faster
when the enjine was turnoff sometime and then open the radiator and fill it
radiator fill cap on 2005 Honda vtx? I'm not sure what your asking. But look behind the left side cover, left of the owner's manual and tool kit box. Maybe that is what you are looking for?
can you please repeat the question?
If the water is circulating, simply fill the radiator while the car is running. If there is an air blockage, a heate hose that loops up, you can install a T fitting in it that will allow the air to escape. Usually running the car while filling will do it.
The radiator of the car must be filled with water upto the brim, so that the engine will remain cool.
Empty the radiator - and re-fill it ! Car anti-freeze is added to the water in the radiator so, if you drain it and re-fill it, you can add a fresh quantity of anti-freeze into the radiator filler hole.
You should fill a radiator with a coolant solution that is specifically formulated for use in automotive cooling systems. Water mixed with the appropriate ratio of coolant is typically recommended to keep the engine running at the right temperature and prevent it from overheating.
First open up the radiator, then there's a drain plug on the bottom of the radiator. Fill with water and drain until clear. Fill it up and good to go.
Fill both, but only remove the radiator cap when the engine has completely cooled off. Obviously have the water pump repaired as soon as possible.
