Pros & Cons

Update Pros and Cons
The AI used to provide these results are constantly improving. These results might change.

Pros

Put it in and drove on a 350 mile trip. Completely ended the problem with my sonic. I plan to rebuild it next summer so just needed to make it last.

There were no globs in the mixture when added back into the radiator. Simply crush tablets into powder form and pour into pressurized coolant surge tank or radiator. Add directly to radiator to stop leaks.

Ac delco tabs are the best. Preliminary results are very encouraging.



Cons

Not off to a great start. Didn't work for a head gasket leak in my trailblazer straight six. The leak is between cylinders so there was no visible evidence of a leak because it was being burned.

For $5 you often get lucky and never see the leak again.

Packaging/appearance


They don't seem like much, n fancy package, no bright entertaining colors.


Highly suggest i keep an extra package in the glove box inside a sealed bag.

Competitiveness


Better than other products out on the market.


All the online forums suggest the lim gasket needs to be replaced, which is a very expensive job.

    My truck has the infamous cracked castech heads


    Posted by a reviewer on Amazon

    My coolant would leak into the combustion chamber and i would have to top it off every week

    It’s not worth investing the time to tear the engine apart and replacing it


    Posted by a reviewer on Amazon

    So i decided to put some of these in the radiator and it’s been roughly 100 miles and i haven’t lost any coolant


    Posted by a reviewer on Amazon

    I would recommend giving these a try if you have the castech head issue
