Once again I'm chasing a pesky coolant leak. I thought I had it solved with a heater hose clamp that I found slightly loose, but this morning I have a couple of drops of coolant on the garage floor, I find a thin film of residue blown back along the block & pan after several WOT passes yesterday and my recovery "tank" (a tube 17"Lx1.5"D) is down about a cup or 1.5cups. I hate stop leak products but with this congested front end it is all but impossible to see the source and I'm frustrated. I know it's been addressed before, but a search for radiator sealer, stop leak, etc brings up any post with any word listed - painful at best. Anyone use the stop leak products? I'm also hampered by the radiator being layed back, so getting the product into the radiator will be difficult - probably have to mix it on the stove or something... Seems I heard at one time that some OEM's used to put Bar's Leak in at the factory?
