Bar's Leak's

Anyone added this stuff to their resevoir tank?

Or will it ruin everything

Don't use any aftermarket sealers. The only recommended sealer mentioned in the shop manual (2001) is GM P/N 3634621, in pellet form. Use 3 pellets when refilling the cooling system.

One of their products is the same as GM's coolant supplement. I wouldn't use any of the other stuff though.

And don't add it to your reservoir. Add it to one of the coolant hoses.

Are you having problems with leaking, though?

I wanna say it's some kind of golden powder or something. But I am not sure.

The GM pellets are organic, made of almondshell, tumeric, etc. They freely move around the cooling system, and don't harm or react with Dexcool. Many of the aftermarket sealers settle in the bottom of the radiator and heater core and become solids. If you were going for an aftermarket sealer, i'd probably look for something organic like cellulose (paper) or the like.

GM retail is only $4.18, do dealers where you live not have it?

[BACK2LIFE]

if that question is for me, i've never looked but most likely they do. mine doesn't even run well it did when i bought it but it had a blown head gasket and crack in the block. i'm putting in a used engine slowly but surely

Thanks for the responses it helped me out.

I might as well go the G.M dealer and the proper stuff.

Ohh yeah ......... the cause of this problem was due to an aftermarket rad cap from NAPA.

Cap from Napa noted. Only buy GM replacement cap...
