Bar's Leaks HDC Radiator Stop Leak Tablet - 60 grams

Clogs the water pump

Deller what great 👍

Function fragments! Utilise 2 tablets !

Muy bueno, detuvo la fuga que con otro producto no había resuelto

All anyone needs to know is IT WORKS. As long as the leak isn't a gaping hole. And it did not clog my heater core.

I had minor coolant leak there would cost over a thousand to repair and I read that GM uses a product like this for small leaks. I added the tablets to my coolant and leak gone.

I had to change head on my boat’s diesel CAT3208. Did not have any problems with the gasket, but head needed to be replaced. However, after the change I noticed small leak around the head gasket. Initially I purchased Bar’s Head Fix, but decided to call the company to get some tips on the installation. The company’s rep, after listening to the nature of my problem, stirred me towards Bar’s tablets. I followed the instructions on the amount, pre diluted tablets, and so far no leak. Just took a 50 mi trip down the coast everything looks good. I was little anxious initially, my engine is 40 years old and I did not properly flushed it, just changed coolant during head replacement procedure. I don’t know how long it is going to last, so far definitely worth it.
