Just follow directions. If you need more put a small amount in.
It may take more than one bottle. Also Its better if you don't put antifreeze if AFTER the Bars If it needs antifreeze, put in before. It is pretty good. And follow directions about letting your car run for a short time. Its all on the bottle. It works better than the "Stop Leak" by Bars.

I was hesitant
I decided not to use it after conducting further investigations. Some people said it clogs up their coolant system causing more damage and money down the line. I decided to find the reason for the leak and was glad I did because one of my flanges was made out of plastic and it had a crack so I replaced that with metal.

Plugged Up Radiator
Do not buy this product. I followed the instructions and poured the product in the Radiator reservoir. This plugged up the outlet tube causing my car to overheat. I had to remove the reservoir and clean the gunk out of it and the hoses.

Working as intended.
Had a cracked radiator where I needed coolant damn near every 40~ish miles. So it was a pretty decent leak.No money to fix it properly, so I grabbed this. It's held strong for the last 2 months with no issues so far of gunking up my system.I drive a beat up '02 Honda Civic. If it wasn't a beater of a car, I'd be too reluctant to try it. But, glad to say it does work.
