Rated 4 out of 5★ by NORVIN Very Good Coolant Super Tech Antifreeze/Coolant is a good product. The blue bottle Super Tech Antifreeze/Coolant is actually made by the same company that makes Prestone. The white bottle Super Tech Antifreeze/Coolant pre-mixed 50/50 with distilled water is made by the same company that makes Peak.I have used Super Tech Antifreeze/Coolant in several vehicles with no bad results. It is important though to back flush the cooling system to get the old coolant and junk out. Prestone makes a back flushing kit to do this with a garden hose. After back flushing, flush with DISTILLED water to get rid of the city water then pour in Super Tech Antifreeze/Coolant. 01/20/2012
Rated 4 out of 5★ by jjeep2009 not bad for the price need to just top up the coolant in my jeep. bought this and a jug of distilled water and mixed it 50/50. i tested my coolant with a coolant/antifreeze tester that i have in my tool box and it was running between -25 and -40. its made by old world industries which is the same manufacturer as peak antifreeze/coolant and the ingredients are exactly the same between the two. just one is a few dollars cheaper. also their both made in the USA so you dont need to worry about throwing your money to a country with low quality control! :-) 08/20/2012
Rated 1 out of 5★ by tech53566 Very Poor Quality This is supposed to be pure antifreeze and not diluted. My car needs 2 gallons of pure antifreeze to set the freeze protection at -25F. I had to buy 3 gallons of the Super Tech "pure" antifreeze to reach the desired protection of -25F. So this stuff is Not pure antifreeze. It would have cost me less money to buy 2 gallons of a well know brand name antifreeze. 06/30/2012
