I ran across a great matrix chart of the various coolants available. Six coolants have checks in the HOAT column, and five of these are listed as meeting DaimlerChrysler OEM specifications.
If the chart is accurate, I'm curious why the Mopar HOAT coolant has a check in the w/out Phosphate column, but the Zerex G-05 does not. I had assumed these two coolants were exactly the same, save the orange vs. yellow dye.
