I wish to know that. I suggest all headache should go to the manufacturer because she did make function test except it does 'block the leaking'. I believe she does not know how to prevent the block of the coolant level sensor; how to prevent the trigger of high temperature warning from the temperature sensor of the engine...etc.

K&W401224 FiberLock Head Gasket & Block Repair - 32 Fl Oz

Q: How do I clean this crap out of my radiator? Followed directions and now my head gasket doesn't leak but my radiator is totally clogged. Rad was new.

It’s a 32 ounce bottle. If you’re putting it in a car you should only use 10 ounces. I wonder if you didn’t use a whole bottle, perhaps? I added a whole bottle to my Kenworth and my problem was solved. I had a Radiator seam leak in a plastic/aluminum radiator

Q: is there a limit to size of leak?

I had a small leak on the head gasket it sealed it fine I believe it would seal a larger leak, be sure to take your thermostat out and flush the cooling system at least four times follow the directions on the bottle.

how clean it

My 01 Civic only took 1/2 of the mixture (1qt sealant + 3qt water), even after burping - it took no more. Is this OK?
