experiences w/Barr's coolant system sealer

I used the pellet variety in my old Chevy van. Worked good, but one of my hoses (the one to my thermostat IIRC) burst open.

 

I used the silvery liquid kind (I know there 2 now, one is concentrate, not that one I don't think), in my old LeBaron, no effect.

 

I put a capsule in my 3.1 Lumina not an hour ago. Can I expect any adverse effects? What if I put another one in?

It's a band-aid. not any kind of fix.. I used it once when I was 16 with absolutely no benefit.. The thing leaked just as much as it did before I put the stuff in.. All Barrs will do is clog up your coolant passages..

I'd stay away from stuff with big pellets... but i have used the stuff that has a copper power in it....... figured it was "soft" and small enough to not cause an problems, besides, I know how to flush a heater core.

You`d be better throwing back at the store you got it from, i recently needed to fix a leaky radiator and a guanatee fix for $160(new premium radiator) vs risk of a fubar`ed engine for less than $20, seemed better to buy a new radiator. Now the engine bay only gets luke warm:lol:

normally, i would say it's a waste of money.......

 

however

 

the 95MC: at about 39K miles(sometime in late 1997 IIRC), it lost the waterpump. a couple of days later, my father notices it throwing some oil into the coolant.... pretty much symptomatic of a bad headgasket caused by the overheating when the waterpump went.

 

well, seeing how he bought the car about 5,000 miles(and only a month or two) before that, he was pissed. he got some Barr's stop-leak, ran it through the cooling system, i believe it was flushed afterwards.

 

the MC is sitting at 204K miles right now. it still seems to mix an incredibly small amount of oil into the coolant, but it is still alive and kicking.

 

 

 

so............. you MAY be able to get away with it.

exactly what night fury said, you need a flush and fill plus repairing whatever was leaking in the first place.

 

expletive included? The leak is fixed for now. What I will do eventually is flush the system and search for the leak. Nothing wrong w/a temp fix if you don't have the time or opportunity to find the leak. Yes the pellet stuff is hazardous to hoses and whatnot, as I mentioned. This stuff, in the capsule, is evidently gentler. Nice and sweet. Muah.
