Bar's Leaks Pelletized Heavy Duty Stop Leak is rated 4.0 out of 5 by 5.
Rated 3 out of 5 by from Cheapest product on shelf, Magic in a bottle, follow the directions on bottle. I have a 2008 F150 and need a intake manifold gasket and don't have the time or money to replace it, so About 3 months ago my truck was misfiring from cylinder. I replaced all spark plugs and found antifreeze in cylinder 5 & 6 sh## that's a head gasket. That's going to cost some money; after doing a lot of research online a lot of ford owner complained about intake manifold leaking under the thermostat housing, one guy tried this stuff it can't hurt so I called a good friend of mine and described everything and tod him about bars leak stop and he said ok but follow the instructions to the letter. Man I got to Pepboys their was price from 3.00 to 50.00 I went back online spent about 40 minutes looking at reviews this one had ok reviews I grabbed 2 bottles. I drained the radiator I don't have a radiator cap so as instructions say took the top hose off installed "liquid product only" I had to delude the pellets in hot water over 5 times like I said don't install the pellets it will clog your heater core and other things. Put everything together started truck "skeptic" and I freaked out for the first half hour I had no head and and thought I blocked heater core then whatever it was broke free and I had heat so I think I poured some pellets. 2 months later stil leak free only used one bottle, other bottle I will save just in case.
