I have a 03’ Honda Civic with about 140k miles on it. Have had a blown head gasket for about a year or so just haven’t had the money to fix it. So every so often I’ll have to refill the antifreeze. Yes, I’ve had it tested it’s the head gasket, with a pinhole leak. Everything else in the cooling-syst…

A simpler solution, which may or may not work, is to pick up a small bottle of the stop leak that Subaru uses. Just add it to the existing coolant without having to drain, flush, etc. It’s less than $5 a bottle and is routinely added whenever the coolant is changed.

I recall something maybe similar to what jdmere describes that I was shown years ago at a good parts place frequented by professionals and with a machine shop. The counter man said GM put it in routinely in new cars. I think it was a vial of small particles, smaller than sand, maybe about 4 oz. volu…

Such products offer some hope for as a last ditch effort at getting a few more miles from an engine. I have seen several cars run for many trouble free miles on such snake oils but wouldn’t recommend taking any long trips depending on the leak being reliably stopped. It’s a cheap roll of the dice. Y…

If you’re going to keep the car I’d bite the bullet and get the head gasket done properly. A sealant like this will probably fix your pinhole leak but it probably will seal other parts of your cooling system as well . . radiator, heater core, thermostat, small coolant passages in the engine, and wh…

Before you spend the money for that stop-leak product, try adding a teaspoon of ground black pepper to the cooling system. The dehydrated pepper will absorb the coolant and soften while flowing thru the cooling system. Then when the pepper finds the leak it will accumulate at the leak and when expo…

@Tester interesting never heard of this method before. But it’s got me wondering if I should try it. So I would add the black pepper into radiator hole? and let it circulate throughout the engine. Is this a permanent fix? sounds like it would breakdown pretty easily. What does everyone else think …

You just add the pepper to the radiator and drive the vehicle. No. It’s not a permanent fix. Be neither is the stuff you pay $60.00 for that claims to do the same thing. Tester

I have worked on countless cars after folks use whatever snake oil they’re sold on to try to fix their leaking head gasket. Unfortunately by that time I’m replacing the water pump, radiator and heater core along with the head gasket due to them being so plugged up with “fix in a bottle”.

I’m working on a car now after running K & W Chemical FiberLock® Head Gasket & Block Repair It’s not the same stuff but, I’m telling you from experience it didn’t turn out good for me. The car started overheating even more quicker. I decide that I was going to keep the car so I took the engine out…

@RodKnox Well I’ll roll the dice. It seems the majority have good luck with it and the ones that don’t either are not following the directions or the leak is just too large to seal. I just want to make sure I am following the directions right so that no mishaps arise.
