96 mercury sable

Date:November 8, 2012
"I had a bad leak in my rad. I couldnt afford to replace it so i decided to try this product for $11. I ran my car for 40 minutes after adding to a cold overflow tank. It has been 2 days and the leak seems to be sealed. I dont know for how long, but as of today it has given me break from the stress of repair bills. That itself is worth the $11. I would recommend this product as an effective, cheap alternative to a costly repair, for those of us who cant afford it at this time."

Watch out for this product

Date:September 27, 2012
"I used this product and followed the instructions to a T on my 2002 Mazda 5 to try to prevent a small leak from leaking and 2 days later, my radiator cover just blew up and all of the hoses are now blocked by this product….on top of having to change the radiator, I know have to get the whole cooling system flushed out at the shop….(cost me $438.00 all together)
Anyway, let’s just say that I am not one that usually complains for nothing, but this time, I have been extremely disappointed by this product (Rislone® Liquid Aluminum™ Cooling System / Radiator Stop ).
I hope an e-mail like mine will make people think twice before buying this prodcut...it would have cost me 150$ less just to change the radiator in the first place..."

Thermostat problem - Use with caution

Date:March 11, 2012
"I bought this to seal a slow seepage from the rad in my Pontiac with a 2.2L 4 cyl.
I added 1/2 bottle and followed the instructions on the bottle.
Success! The leak seems to have stopped.
The first run after adding it was 100km of highway and the engine temperature was between 86 and 87 degrees celsius. Usually my engine would run 88 to 90 degrees celsius. So it does lower the running temperature a couple degrees as stated.
Now for one problem I had after adding this sealant; After the first 100km's of highway driving I shut off the car for about 15 minutes, got back in and drove about 15 minutes of city driving. Then all of a sudden my engine temperatures went as high as 92 to 98 degrees celsius. My car has never run higher than 90 degrees before. I was getting heat through my vents so I knew my rad wasn't blocked. It seems that the thermostat must have stuck in the closed position. This lasted for about 45 minutes of city driving with temperatures ranging from 92 to 98 degrees. My engine is running at normal temperatures again and seems ok now.
If this problem happens again I'm going to flush the system and refill it.
I'm starting to think I should have just replaced the rad for the $160 cost of a new one.
If you're going to use this stuff, my recommendation is to monitor your engine temperature closely for a couple days after using this sealer just in case your thermostat sticks closed and causes an overheat issue.
I would also suggest adding only 1/4 bottle at a time until the leaks stops, this way you don't have a lot of this stuff in your coolant.
Good luck.

Saved me a $500 repair bill!!!!!

Date:January 15, 2012
"After I noticed a large puddle of radiator fluid on my driveway I was more then a little worried. I'm saving for a wedding and really didn't need a huge repair bill. Luckily my neighbor is pretty car savvy and was able to inspect the problem. After pricing out all the parts it was going to cost well over $500 with labor.
I found this product mentioned on car forums and even though I am pretty skeptical of any "stop leak" products I decided to try it and gamble the $10.
I followed the directions for a cold engine applications and drove around for 30 minuets instead of the recommended 15-20 just to be safe.
It has been well over a week now and there is no evidence of any leaks. The warning lights turned off and the fluid is holding in the radiator.
Very very happy with this product."

Better than the cost of a big repair

Date:October 16, 2010
"I have a 12 year old Volvo which had an unidentified coolant leak from somewhere under the front end. The leak was enough that at times I could not actually see anything dripping from under the car, but at others I would come out and both see the dripping and find a large puddle under the front of the car. Either way, I was having to top off the overflow bottle up every other week or so. Because this car has no rad cap, I added the Rislone via the overflow bottle, which they said was OK to do, and at that, only used about half the bottle, and the leak is gone. Very easy and probably saved me a lot over the repair, and I believe that now the car is also running cooler."
