Probably all of it. Unless the volume of water in the system is known, it is impossible to know how much to remove and how much antifreeze is to be added to achieve the proper mixture. The correct mix is 1/2 water, 1/2 antifreeze at a minimum, but ideally, the mixture should be 70% antifreeze with 30% water.
We always renew the antifreeze in our car before winter.
No. The antifreeze has to be mixed with the water before the water freezes.
Should be a plug at the bottom or rear of the radiator
I need to fill my car's radiator with antifreeze before winter comes.
Drain the antifreeze.
You don't. Wait for the engine to cool down to avoid getting burned before you open radiator cap.
remove bottom radiator hose to drain system. flush system a few time before adding antifreeze.
well you can either open the bleeder screw on the bottom of the radiator if it has one, or you can loosen the clamp on the bottom hose of the radiator and watch out for the big gush of antifreeze coming at you, take the radiator cap of before hand as a vent. good luck.
Is it at the correct fill level ? If the radiator is old it is possible some corrosion has blocked up soemwhere and the radiator may need anther draining and flush through with water till it clears out.
ON THE BOTTOM OF THE RADIATOR THERE IS A SPIGOT TO DRAIN THE RADIATOR TURN THIS TILL IT OPENS UP AND YOURE RADIATOR FLUID WILL DRAIN RIGHT OUT THE BOTTOM THEN TO FILL MIX ANTIFREEZE AND WATER 50/50 UNLESS ALREADY PREMIXED THEN FILL START CAR UP AND CONTINUE FILLING TILL RADIATOR IS FULL MAKE SHURE U CLOSE THE SPIGGOT IN THE BOTTOM OF THE READIATOR FIRST BEFORE FILLING
To change the antifreeze on a 2003 Saturn Ion-3, locate the drain plug on the bottom of the radiator. Drain the liquid into a pan before refilling it.
First you must make sure that the car is a little cool. then you must drain out the antifreeze that is in the system. Remove the hose that connects to the radiator. Then on the fan that is between the radiator and the engine you must remove the screws that hold it in place. then disconnect the hoses that are on the bottom left-hand side if your are facing the car. Then there are also connectors that are from the radiator that are connected to the actual car that need to be disconnected. Make sure that fan is totally disconnected from the radiator. then pull out the radiator. When you put the new radiator in make sure that your are not caught on anything. then put the screws back in that hold the radiator in place. then out the hoses on in the correct spot and make sure that YOU PUT THE CLAMPS ON THE HOSE IN THE EXACT SAME PLACE AS THEY WERE BEFORE otherwise you will have a slow leak and the engine will overheat. Then put the clamp back on the top of the radiator (NOTE: IF THE AFTERMARKET RADIATOR IS TOO BIG THE ORIGINAL CLAMP WILL NOT FIT OVER THE NEW RADIATOR. SO YOU WILL NEED TO CUT OFF THE BRACKET THAT IS IN THE WAY WHICH IS THE PIECE CLOSER TO YOU IF YOU ARE LOOKING AT IT. CUT OFF WITH A DREMEL OR SOMETHING.) then put antifreeze in the radiator itself and then when you cannot put anymore start the car with the cap off and it will go down. then pour more antifreeze till it is full. MAKE SURE THAT YOU HAVE ENOUGH ANTIFREEZE.IT MIGHT TAKE A WHILE TILL ALL THE ANTIFREEZE IS FULLY REPLACED. and that is how you replace a radiator.
