| Read the article... Does Samco and higher quality manufacturers find a way to reduce properties of the silicone to make it less porous? Last year I drove mainly from June to Aug about 3K miles, noticed by the end of the summer I need to drop in coolant can't remember how much but it was not not anything drastic. Would you contribute that to the silicone hoses? Also, is it safe to say anyone with silicone if they keep an eye on the coolant levels is doing the best option is silicone?
