Acdelco seal tabs

[Monk]

Just wanted to say, (I know it's not a "fix") but WOW these tabs since summer have 100% fixed the coolant Pressure issues I had, I kept bleeding air daily, and now, (after putting in the tabs)I waited a month and today opened Tstat area first and only antifreeze came out, "zero air!! "

I have other heads already but figured I'd have to keep bleeding air pressure through the winter, but this stuff is insane great!!!

As some say, put even a few tabs in for Maintenence ,it's the real deal, well for my issue, very impressed,... Zero extra pressure!!

Lol when it gets warmer I plan to do it right but rather wait for warmer weather, hehe
