I have water pouring from the side of the engine

radiator hose or rusted out welsh plug
get a coolant system pressure test done to determine the exact location of the leak

Sounds Ike a frost plug has gone bad. You need to get under the vehicle and take a look. Year, make, model, and engine size?

you have to figure out where the leak is first and u cam add water while running just dont do it when car is hot

check by-pass connection of cooling system going to a/c evaporator for broken hose or plastic tubing.

Sure could be. Or a hose or a gasket somewhere.
You'll need to fill up the radiator and run the engine to look for the leak.
It may have to get up to operating temp before you see anything.

does it have a 4.0 ltr engine ...most common causes is the intake bolts on the front corners above the water pump...check to see if there tight and if they are..apply sealer to threads and reinstall..

hi all i have fixed the problem please note this is for the renault scenic 1.9 dti 1998 reg. i had taken the casing off on top of the engine the one that covers it all for noise meaning the black cover. and looking back to the bulk head to the right hand side you can see 2 hoses which are side by side which are going into the car i dis connected both hoses and got a hose pipe and blasted them into the heater matrix with water (cold) and i dont no if this was a good idea but i got a mop bucket full of hot water reason why hot is because the engine was hot and poured it in to the tank where you top up your water just to fluss the system when it was filling i started the engine then kept pouring the water in when bucket was empty turned engine of asap re connected both hoses. on the LARGE hose you have a bleed screw i had taken that of completly then started the engine to let the water bleed through but again kept pouring water in the top up tank half a mop bucket whilst engine was running i replaced the bleed screw and hey presto the job was done i have not had any heating in the car for 4 yrs but now its hot hot hot. hope this helps to all with the scenic

You have a bad casting plug in the side of the engine. A lot of people call them freeze plugs because they pop out if the coolant freezes. They also rust through. They are driven in place and the size can be looked up at the parts store. You will want to change all of them . Lee

Open the temp gauge sensor (located in the back , top of the engine) and please make sure to open the lock and not to lose it as you will need it to tighten the sensor in its place. Open the water bottle and pour water in it and let the water come out from the back (the sensor) , you will see air bubbles coming out with the water , but keep on pouring water till you see no bubbles what so ever. put sensor back in its place while water bottle is full and while water is still coming out from the back to make sure that no air escapes inside with the water.You might need another person to help you pouring water while you are in the back.

Could you post what size engine you have in your car?
