Through my years of travels one of the aftermarket people I ran into told me there were as many as 5 different grades of parts from the aftermarket. At that time he claimed NAPA generally had the highest quality parts and the others were generally 1 or 2 notches lower.

So you probably get what you pay for.

I do know this when I was a kid we always replaced the upper and lower radiator hoses every few years, it seemed like there were a lot of failures back then of these.

Now we never replace them. So I am betting the quality of all radiators hoses has probably come up in the last 50 years.. we don’t replace v belts either now?
