Replacing leaking hose and refill with anti-freeze/coolant. What is the proper fluid amount and mixture?

Assuming you see liquid somewhere, it can only be one or more of these fluids:
Fuel (gasoline)
Oil
Coolant (water/anti-freeze)

Normally, these three are separate, and all can leak. Depending on the quantity of the leak, only fuel is truly dangerous because it can catch fire easily. Minor oil leaks can be ignored for years, as long as you check oil and add as needed. Minor coolant leaks can also be ignored, as long as you keep the level up.

Coolant leaks are typically caused by hoses getting old, and replacing radiator hoses isn't difficult, just messy. Oil leaks are often harder, though the last one I fixed turned out to be trivial (oil filter loose).

Without visually seeing your vehicle, you basically have to drain the radiator at the drain valve (sometimes referred to as the petcock) at the bottom corner of your radiator into a drain pan. Then in no particular order remove both upper and lower radiator hoses. Remove the electric fans if so equipped, (carefully remove all electrical connectors as not to break them in the process) and set it aside. Then remove the transcooler lines top and bottom, carefully removing the retaining clips holding these lines on. Again let these lines drain the fluid into a pan and if possible save this fluid in a clean manner so that it can be put back in the vehicle. Then remove any brackets holding the radiator in place including those attached to the condensor that sit in front of the radiator if it is attached directly to the radiator. Of course their may be other parts attached that must be removed depending on your model, but that is the basics of removing it from the vehicle.Then reverse the process in installing the new radiator, Putting either the anti-freeze/coolant that you drained out back in or replacing it with a fresh fifty-fifty mixture of anti-freeze /coolant. Making sure the transmission fluid is topped off to the proper amount of fluid or if you were able to save the fluid put it back in. Another factor is getting the transcooler lines snapped back in properly as to not have them popping apart going down the road. But the largest most important factor when installing the new radiator is to be extremely careful not to ding or damage the fins of the new radiator because they will leak and you will not be able to repair them unless you are extremely talented at radiator repair. Good luck

Remove the radiator cap.
Remove the radiator drain bung from the bottom of the radiator.

Drain fluid into a container.

If no fluid present, then refill radiator and perform a system pressure check.

Once all fluid has been drained, and any faults repaired, then refil with a 50-50 water to anti freeze mixture.

It can do harm to seals (the alcohol in washer solvent) I'd flush cooling system and refill w/ new anti freeze.

the sweet sickly smell is normal for new anti freeze.once you have run the car for a couple of miles the smell will dissipate.the white foamlike stuff is chalk/lime in the water,harmless.

The mixture of of anti-freeze/coolant to water should always be 50-50, or 50% anti-freeze/coolant and 50% water, and the mixture should not exceed 75-25 or 75% anti-freeze/coolant and 25% water. If the mixture is more that 75-25 then the anti-freeze/coolant will not function properly in the cooling system and it can actually cause the engine to overheat, and if the mixture is below 50-50 then the anti-freeze/coolant protection will be deminished.

U need to use 50/50 mixture of long life/extendedlife coolant availible from any automotive parts store for around $8 per gallon. but you must have a leak, check for coolant leaking when the car is running, don't overheat this engine or u will blow the cylinder head gasket, a $1000.00 repair.

if u didn't run the engine no, just use a hose and flush tank, if u did run the engine just drain and refill the radiator with 50/50 solution of long life antifreeze, also flush the coolant reservoir with a hose as well..

the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00

First of all ensure that your car is leaking coolant fluid, and what is dripping is not just water condensation from the air conditioner.
If you have a coolant liquid leak, it can be from one of the ducts leading to radiator , from water pump or radiator itself. Check liquid levels, and if you have a leak have the car inspected by a qualified mechanic.
A broken water pump, for example, can cause your motor to blow in few miles.
