Barrโs is the way to go.
Iโd say it worked great, I did something very stupid, I had my van idling on my driveway for about twenty minutes or so and my neighbour saw smoke coming from it and alerted me, most of the fluid leaked out of the radiator and in the process it sprung a couple of leaks, went and checked on line with my very good friend the one and only Scotty Kilmer and Barr,s radiator stop leak is what he swore by, no regrets using it, most of the leaks are gone just a minor drip from what I believe is coming from the drain plug, glad I used Barrโs Stop Leak

WORKED GREAT. EMERGENCY INSURANCE PAID OFF.
Just used an almost 5-year old bottle of this stuff on a 2007 F150 4.6L with the normal radiator, it was pissing everywhere, it got the truck 12 miles home without a drop leaking!
