There are two kinds on their website. One that can be used while coolant is still in the vehicle (Head Gasket Fix), and one that requires all coolant to be drained before it is used (Head Gasket Repair). One may work better than the other.
AnswerMay plug heater coreI just used Bar's leaks block seal permanent head gasket fix 1 step (silver bottle 24 oz) $29.99 at O'reilley's , It worked excellent for 6 days on 1997 v-6 3.1 liter engine (it did not plug any heater lines)
bars leak will plugg up your heater core meny times, good luck!
You should replace the head gasket. This repair is critical to the better performance of the vehicle, and to prevent future damage of the engine.
No, it will not. That is used as an emergency repair. The only fix for a blown head gasket is to replace it.
You possibly have a leak in the cylinder head gasket.You possibly have a leak in the head gasket.
The theory is that it will plug the leak area and harden there. I've known folks who have had some short term success with Bars products but sooner or later you are going to have to repair that head gasket the right way. The only real draw back to using these products is that they may end up clogging the radiator or heater core as well.
This is only used as an emergency repair and is NOT a permanent fix. The only permanent fix is to replace the gasket.
Take it to a mechenic asap....lady%preach
Head or head gasket leak
If it is leaking from a bad head gasket, it is because of a bad head gasket. If it is leaking from a bad intake manifold gasket, it is because of a bad intake manifold gasket.
If you ran your car too hot you may have warped the head which would cause your head gasket to leak water or oil. You need also to hone the heads to make them flat again.
No not hardly. The only thing that stuff will do is stop up your heater core and radiator. They have never made anything in a can are bottle that would fix a blown head gasket.
A head leak can be detected by checking the coolant for CO ( carbon monoxide ) gas. Many repair shops can do this check for a nominal fee. WB
