The Power to Clean

Hello, i wanted to tell you that Thermocure saved me from rebuilding my engine. i was having overheating issues with my all original 1987 monte carlo ss. the 305 engine has 32,000 original miles. I have tried everything else and the guy at Walmart said we heard alot of great things about Thermocure. so i bought it. i went home drain my system and put it in and drove it for a couple time a day for one week. i drain the system and the water was black. im not sure i can tell you how much the water smelled. It smelled like pound scum. I have never seen or smelled anything like it. mind you i have used all the other flushes from Walmart and my local part store. The anti-freeze that came out was clear and look good. Your flush clean something in the system that the other could not. i removed the thermostat and raised the system 3 times. I put new anti-freeze back in and the engine runs at 195 degree F. before it was around 235 to 245. i have a 195 thermostat in it. If this has not worked i would have been forced to rebuild the engine. thank you for such a great product.
This stuff worked awesome. 2003 chevy tahoe. I had to use 2 because 1 jug only treats 2 gallons. Capacity on my Tahoe is almost 4 gallons. I drained my coolant and added these 2 with water. Drove it for a week because I really don't drive much everyday. Flushed it backwards and forwards a few times just to make sure I got everything out. Then refilled with coolant and finally after multiple flushes from garages I got it working better than ever. My heat doesn't cool down now when I'm at a stoplight and it actually gets so hot that if you hold your hand in front of the vent for more than 15 seconds it will start burning you. I will always be a lifelong customer as long as they don't change. Wish I would have tried this sooner. I've spent over 500 dollars on coolant flushes in the last 18 months. My total investment for this and new coolant is 60 dollars so save yourself a lot of grief and try this first.
I USED THERM O CURE IN MY 1947 LINCOLN V12 MOTOR. THIS CAR HAD BEEN STORED FOR 52 YEARS I NEW THAT THE CAST IRON BLOCK HAD A LOT OF RUST IN IT. SO I PUT 2 QUARTS IN THE RADIATOR [WHICH IS 5 1/2 GALLONS] AND LEFT IT IN FOR 2 WEEKS. WHEN I DRAINED IT IT LOOKED LIKE MUD. I RINSED IT UNTIL THE WATER WAS CLEAR. I THEN THOUGHT I WOULD JUST DO IT ONE MORE TIME JUST AS A TEST, SO I REPEATED IT THE 2ND TIME I WAS AMAZED. THE WATER THAT CAME OUT WAS CLEAR AS CREEK WATER I THEN PUT MY ANTI-FREEZE BACK IN. I LIVE IN ARIZONA WITH 110 DEGREES WEATHER AND THIS V12 RUNS AT NORMAL TEMPERATURE ALL THE TIME IT IS AN AMAZING PRODUCT. I HAVE TURNED SOME OF MY FRIENDS ON TO IT AND THEY HAVE COME UP WITH THE SAME GOOD RESULTS. THIS PRODUCT WILL SAVE YOUR MOTOR.
This stuff is awesome. I did 13 distilled water flushes and water was any different than the first flush. I put this in and drove it for a couple of days and nasty blobs off goo encapsulating rust came out. I think it took me 3 more flushes to get all of that out and I see this made a few people unhappy but just be patient and keep flushing till clear.
