This worked great and saved me costly repairs.
Edit: 5 months & a super hot summer later and it’s still repaired. I still highly recommend

FIXED IT
almost 5 months ago
legit

It took two treatments, but this did what it claims to do: it stopped a coolant leak in on of the hose connections where the system passes through my firewall. It’s been a few months (and several thousand miles) since I used it, and the leak has not come back

Works like it supposed to it sealed up my leak with one application

Was very reluctant to try this but figured a major player in the coolant industry wasn’t in the business of ruining engines so we took a chance and put two of these bottles in a fairly large cooling system. Four months later we’ve not added any coolant and are not experiencing any issues. A $25 investment in this Prestone product has so far saved us $1300 for a radiator, not to mention the truck downtime as we do most of our own repairs.

When I bought this I gave it about a 5% chance that it actually might work. I was 95% wrong. I had a mystery leak and my system wouldn’t pressurize. I added this to my radiator and topped it off with coolant while my engine was cold and drove 2.6 miles to work. Upon arrival I found that my upper radiator hose was hard as a rock and my system was fully pressurized. I wish I could give it 10 stars.

Had a small leak in the seam of the radiator of my Camry. Stopped the leak. It has been 2 months and is still holding. However, it did also clog the overflow tank hose and had to be blown out to clear it

Well it got me out of a tough spot, had a water pump leaking and going out on the trail. Tried this instead of replacing on the road. Stuff lasted me 800 miles before the Water Pump cracked. Definitely not a long term solution but was able to get me home to fix the real issue.
