Bar's Leaks Head Seal Blown Head Gasket Repair Additive, 33.8 oz

from Labman

This is an excellent product. No need to remove the thermostat to use,works fast and as long as you leave it in the cooling system it will keep on working. I have had no problem with any type of clog or slowdown as far as the radiator or any part of the system goes.

from Dawg

I had coolant leaking. Refilling once every 4-5 days thru my tailpipe. Could not find the problem at all. New head gasket is 1500 bucks. I tried Bars about 3 weeks ago. It works. Follow the directions. Careful not to overfill. I spilled some on the driveway and its a silver white mess still.
