I recently tried Liqui Moly Radiator Stop Leak in my older vehicle that had developed a small coolant leak, and I’m genuinely impressed with the results. I’ve used other stop leak products in the past, but this one stood out for its ease of use, fast action, and trusted brand quality. The instructions are straightforward—just shake well and pour it into the cooling system when the engine is warm (but not hot). Within minutes of running the engine, I noticed the coolant level stopped dropping, and the leak around the radiator seam appeared completely sealed. What I appreciate most is that it doesn’t clog the system or create sludge, which can be a problem with lower-quality products. My heater continued to work perfectly, and the engine temperature stayed normal. It’s compatible with all types of coolant, which adds to the convenience. Overall, Liqui Moly Radiator Stop Leak is a solid, trustworthy product that can extend the life of your radiator and save you from costly repairs in a pinch. Highly recommended as a temporary solution or preventative measure.

Mi S10 1994 4.3 tbi empezó a gotear por encima de la marcha, aplique la mitad de la lata y detuvo la gotera casi de inmediato, llegué a casa, estacione el vehículo y dejo de estar la mancha, lleva una semana y mi nivel de anticongelante dejo de caer, me funcionó mejor que artículos baratos de AutoZone
