Q:2000 Chevrolet Astro V6 - there are two different looking lower radiator hoses pictured, Gates GAT22230, and Dayco DY71906. Which one is correct? Show Less
Kurt S.
A:BEST ANSWERHi Kurt, I'm pleased to assist you. While both Gates GAT22230 and Dayco DY71906 are listed as compatible lower radiator hoses for the 2000 Chevrolet Astro V6, they might have slight differences in design or materials. Look for the original equipment manufacturer (OEM) part number on the existing hose or in your car's repair manual. Match that number to the Gates or Dayco part number listings to ensure compatibility. Let me provide you with three links below for faster navigation in purchasing the required part/s. I hope this helps, and enjoy shopping!
