Bests & Worsts Reviews from Amazon

It is no secret that GM has thousands of unhappy customers due to bad design of intake manifold gaskets, look it up on the web. After having the intake gaskets replaced three years ago they went again, they last about three years before blowing again due to bad gaskets and the effects of DexCool. I parked my vehicle trying to decide what to do. After much internet research I decided to tr{ this product. I am very pleased to say it works and is well worth the price. I do not know how long the fix will last but at least I can use my vehicle again, if I get another year of driving out of it I'll be happy. Again, it works. As an old broken down "wrench" I would have torn into it when I was younger but am not going to go through $2700 repair every two to three years. Update, 3/28/2012 Vehicle still running with no leaks or loss of coolant. You will need to keep it clear of your radiator cap so coolant can pull back from the overflow resivoir. This stuff works, look at the reviews here they aren't fabrications. Update, 10/22/2012 Still running just fine. Arizona summers find all sorts of weak spots in your cooling system, none arose this past year or summer. The coolant loss situation I faced was as bad as any I've read about here or other sites so it's not like it was minor. Maybe I am lucky but this product has given me use of my "family hauler" vehicle for just short of one year and another 5K miles of around town use. Update 12/15/2012 Well the leak fix popped last week and it's back to sucking coolant into the intake manifold. I will flush the cooling system and try the Bars Leaks again. I got just over a year of vehicle use with it so if you get results like this it's worth it. Update 1/21/2013, Weather was nice today so I added another bottle of this product ran it for 15 minutes while temperature held steady. Upon cooling down and checking fluid levers I drove eight miles with temperature holding right where it should. If past performance is going to repeat I should be drivable for another year. Update 08/09/2013 vehicle still drivable through another hot summer, even days up to 114 degrees. Would not of course take a long trip in it but for around town use it's holding up. Your case may be different but if your vehicle is old enough to have virtually no trade in value and need something to get you to and from work it is worth a try.
