I hear it's a powder that runs through the cooling system and "fills" in any holes/cracks temporarily. I don't want to be using anything that may make things worse while I go tear it up in the Sierra Nevadas!
Thanks again for any advise you guys (or gals) might be able to provide!!!
It's called "barsleak", and I know for sure it comes as a pellet/liquid, basically looks like molases in the jar filled with pellets (I think there is also something called Alumaseal that is basically powdered aluminum/mixture ) that disolve once they hit a certain temperature (like normal driving temps or slightly less). While it will seal pinhole types of leaks, it can play havoc on the rest of your cooling system, like clogging up a radiator if the radiator is already restricted in some form (like most old radiators are), so I'd skip the barsleak and have the system pressure tested to find exactly where the leak is coming from to avoid problems down the line.
I did keep a jar of barsleak (and a gallon of coolant) in my last jeep (and it did come in handy when my waterpump sprung a leak in a faulty casting - but only slowed it down enough to drive the last 20 miles to the dealership to get it repaired ) since if you do get a hole and detect it quick enough, you can put this stuff in, and it may slow down a slow leak enough to get to a repair facility where the whole system should be properly flushed, fixed and refilled.
