Para calcular a classificação geral de estrelas e a análise percentual por estrela, não usamos uma média simples. Em vez disso, nosso sistema considera coisas como se uma avaliação é recente e se o avaliador comprou o item na Amazon. Ele também analisa avaliações para verificar a confiabilidade.
I had really hoped this would work. I put two bottles in the radiator of my 06 Ram 5.9L Diesel and just got back from a trip towing my travel trailer. No effect (no lowering of temps) that I could detect. Truck ran just like it always did - same temps as always - I actually think it ran a slight bit hotter than usual. I probably wasted my money. Will not buy again.
Added to 50/50 antifreeze mix, hoping to get even 5° drop. Didn't help a thing. Same temperature, it seems longer to reach operation temperature now, but once it gets there it does nothing. 2006 Subaru WRX STI
2011 Silverado 5.3L 64k miles. One week after adding product to coolant there was no change in temp according to the dash guage. Was not running hot to begin with so probably not needed. Maybe it will prolong the original GM coolant performance and save in the long run. Maybe.
Brown gunk appeared one day after install, and has been getting worse. Performed radiator flush prior to install, and replaced all fluids with new 50/50 Prestone antifreeze and distilled water. Racers seem to like this when used with water only, and no glycol, but no good in your everyday driver.
