Ive always been told to stay away from any "stop leak" type additive for oil or coolant. First thing i would do is try to see if you can trace the problem before possibly gunking up your radiator.

when you run stuff that is purposely trying to gunk up (patch) the leak, its going to gunk up and give you problems in the future...do it right the first time, find out where its leaking...

whynns or B&G dont use any of that powder ****, if it isnt leaking bad just starting these 2 will be fine, make sure its for the right color antifreeze, you can get the stop leak for both colors...

correction its wynns not whynns, read the directions, its a fluid additive so its not going to hurt your core or pump or anything eles, used it in a lot of cars over a lot of years, but plan in the near future to get it fixed the right way.

Well it definitely is burning the coolant, I can smell it at startup. My daily is an impala with the 3400 v6 that I found out is notorious for leaking lower intake manifold gaskets. Is there a way to narrow down if its the intake manifold gasket or if its a head gasket instead?
