PEAK OET Extended Life Red/Pink 50/50 Prediluted Antifreeze/Coolant for Asian Vehicles. This is what I used in mine. It's pink as per the original one. The color does matter but it varies depending on the manufacturer, it's confusing.
If you want to use the OEM part you can search UM020 CH263 that's the part number. I usually do OEM but can't wait to get it because I was traveling by the time I noticed the low coolant level.
