Whats the best Radiator sealer out there?? Which ones to avoid??
I can see a small leak on my radiator. Im overheating a lil bit. Just want to know if someone has successfully sealed thier radiator. Or have you had a bad experience with the sealers? Thanks.

Prestone super sealer is the best I found .Sealed a head gasket leak and lasted 20,000 miles before it failed.

The stuff that comes in the little tube-filled with grey powder-sorry don't remember the name but it's very common. It works great and doesn't seem to clog stuff up.

doesent that crap mess with your heater core and all your water passages i heard it accumulates in it an viola no heat and eventualy core failure and we all know what that means , ripping the dash out the best fix is a permanant one especally with a very expencive aluminium motor that is very difficult to replace heat and aluminium dont mix!

Yeah-'Alumiseal'-is the name. First off I want to point out that on the late model F-bodies replacing the heater core only requires removing the glove box-not the whole dash. Secondly using stop leak like 'Alumiseal' doesn't always clog stuff up. If you're on a serious budget you have to do what you have to do-I've been there=done that.
