Tim this stuff worked for me in and old Toyota. My son ran it without water on the way to college. When I towed it home and put antifreeze in it to check it out it actually blew it out the exhaust pipe. Used this stuff and drove it for 3 years. Sold it to a guy and he drove it for quite a while. You have to drain out all the old antifreeze and take out the stat. Put this in and then run it till it stops leaking. It didn't take long. K&W block sealant.
