Rislone Liquid Copper Block Seal Intake/Radiator Stop Leak
Works No Issues Please READ!!! Follow This
Bought this product 2012 around the middle of decemiber .First off i drive a 1993 cavalier z24 with the 3400 swapped motor so it has the 3.4 sfi motor from a 2002 pontiac gt which is well known for intake gasket leaks.It did fix the leak but a bought 2 of them is this is why .To make this easy on everybody heres what you need to do .FIRST OFF!! do not bother putting this product in your overfill pressure tank i did this it takes to long for the product to work and reach the motor .When i did this didnt do much to stop leak IT HAS TO BE PUT DIRECTLY INTO YOUR UPPER RAD HOSE OR RAD TO WORK!!! .Dont waste your time putting in overflow tank i had to buy another bottle .Run your car for about 15 mins make sure the upper rad hose is hot and you feel the coolant running threw it.Ive heard this product can cause blockaqe in other reviews .If the havent maintained your coolant system or ever had it flushed over the years your coolant system can get blocked easy

Try to pour directly in the radiator. Don't try putting in the overflow because it may not all get into the radiator thus making it less effective and could possibly even clog the lines.
And trust me it works perfectly!

Worked. But at what sacrifice?
I had a small coolant leak at the head gasket dripping down the front of the block that was getting bigger. Used this product and it stopped the leak. Followed directions to the letter. Used half the bottle on my 20yr old 4 cyl car. Watched it work its magic and stop the leak. Now the issue starts where I'm driving around with a heater core that now produces half the heat I used to get. I must now drive around with windows half fogged up. Seems to have somehow partially blocked it. Two months prior to this, my coolant system had been completely drained, flushed, new rad, new water pump, new t-start. Use with caution as it may block small areas where coolant is required to flow.

engine overheating due to lose af coolant, 2000 silhoutte(chevy venture cousin), notorious for head and manifold leaks, i had both, mechanic tried some gm sealant that goes into the antifreeze, it did not work, mechanic said to get rid of it with 260000 km not worth fixing it, head gasket was repaired once by previous owner.
bought this stuff for $12 since i had nothing to loose, poured right into rad, waited for thormastat to open(15min) then followed instructions, i think i let it run for 10-15mins after thermostat opened up, then let it cool overnight. it worked been 3 months now no lose of coolant therefore no overheating.
i might flush it out b4 winter comes because of what i read in previous posts

Saved me $500 for intake manifold leak
I used it on a 1998 lincoln towncar with the 4.6 sohc, I poured it directly into the thermostat housing/intake manifold coolant passage. After I poured it in I sealed up the outlet and pressurized the system with my compressor and some pipe fittings which pushed this stuff into the crack. I removed the bulk of the extra afterwards but some was still in there to clog the thermostat.
It has sealed the plastic intake manifold for a year and a half now, no leaks since. i had to clean the thermostat about a month after the application which was pretty easy(boiled in hot water& vinegar).
I recommend this product if your going to use it as a temporary fix but I would avoid at all costs putting it through the radiator; it may clog it up.

This product works like a magic but caused over heating after a week of remaining in the system.I had to flush my entire cooling system to remove it completely and it also plugged the rad caps pressure relief valve so the cap had to replaced too.If you do use it make sure to flush the cooling system within a week unlike it says in the instruction of not flushing.
