Review on ACDelco 1149328 GM Original Equipment: Dex-Cool Leak Detection Tracer Dye - 1 oz by Jose Moran

Revainrating 5 out of 5

Since it sure is dex cool, I don't have to flush the coolant.

Works. You need UV light to see the crystal, but I was able to see where all of my antifreeze (water pump) leaked by simply putting this bottle in my surge tank and driving for a couple of days to get it running through the coolant bring to . System. Since it sure is dex cool, I don't have to flush the coolant immediately so I can fix the leak in my spare time.

Pros
  • Practical thing
Cons
  • High price
