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

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.

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.
