Depends on how big the hole is. Mostly all that stuff does is clog up your radiator and block, though.
Might just want to bypass the heater core, if you have a bad leak, and repair it at your leisure before winter returns.

I wouldn't use that stop leak stuff at all. That stuff clogs up everything in the cooling system and then you have major headaches. A new heater core is cheaper than a plugged radiator, and even though it may be a pain to change, if you don't have the time to fix it right, when are you going to have time to fix it again?

Yeah... if I wasn't clear above, I strongly recommend NOT using such products. Over in the Jaguar world, stop leak (especially in the form of Barr's Leaks) is also known as "Stuck Heads" and is one of the reasons that it can sometimes be all but impossible to remove the head from an 80's Jaguar inline six - you can even hang the entire car by the head and it won't come off.
In other words, DO NOT USE.

Well, some manufacturers actually recommended it in their manuals for a while (60's-80's) but they finally figured out that it was causing too much warranty work and p***ing the customers off. No current manufacturer recommends it in their cars that I'm aware of, and as you say, it will void the warranty on most of them.

New GM cars came from the factory with a version of Barrs Stop Leak already added to the radiator. Doesn't say much for GM, but I doubt they would add something that would ruin the engine.

You got documentation on that? I had read that they stopped that in 95 or so, when they started up with DexCool.

I was recalling it from my wife's Cavalier (1992). As for what goes out the door now, I haven't owned a GM car since 1996. I have heard claims that it still goes into the Inline 4s and the some of the V8s but no documentation.

OK, yeah, GM was the last of the manufacturers to stop using it. It's thought that that contributed to the S-truck coolant system sludging up under DexCool. The docs I read said that GM stopped using it in 95.
