What's the best addictive for some leakage in the cooling system of a car?
I have a 2000 Chevy Impala that I need to add some coolant from time to time. What the best item on the market to use?

Anything other then antifreeze will plug up the radiator and heater core.
Plugged radiators cause over heating and plugged heater cores cause no heat in the Winter.

You must mean additive.
The same, only different.
Advice from a career mechanic:
If your radiator leaks, replace it.
If your heater core leaks, replace it.
If a hose leaks, replace it.
If you have an internal leak in your engine, like a head gasket leaking, then you need to remove the warped cylinder head and get it repaired or get a replacement, and reinstall it with a new cylinder head gasket.
Where is the leak?
Do you know?
Do you see leakage, wetness, steam or dripping?
Or is it milky looking engine oil?
Or is it an empty coolant reservoir all the time?
Sometimes the cure is simple and inexpensive. Sometimes the cure is straightforward, but not inexpensive.
Which car do you have?

money. PUt money in the radiator after you check for leaking hoses / clamps. It's also POSSIBLE that you've got a head gasket problem if you can't find where the AF comes out of the car.

They say those additives can cause problems down the road. You're better off figuring out where the leak is. If it's something simple, fix it. My coolant reservoir had a tiny hole in the top corner. It was above the coolant level, but it must have sloshed out when I went around a curve, over a bump, etc. For $15 on ebay I got an aftermarket one, problem solved. If it's something more expensive, maybe just buy more coolant.

It's additive, not addictive. Unless your car is hooked on meth.

The best is to find the leak and fix it. If you don't see coolant dripping under the car, it could be a head gasket.
