Bar's Leaks was the choice back in the day. May cost you your radiator if it is allready gummed up. Read the directions. Run the truck up to temperature, dump it in then drive an hour.

All that crud floats around and eventually plugs your block passages and radiator. It will stop or slow it for awhile.

The only way to do it is replace the core. Not the easiest to do but pretty cheap.

Ground black pepper a tablespoon full is all that is needed! ran my "78" with this fix for 3 years till I could finally afford a new radiator. It stopped all weeping and leaks, checked level once a week and never needed to add to it during the 3 year period.

replacement heater cores are $23 to under $50. I would bypass it and save up for a core and hose clamps.
