Quick question here. I'm going to pick up a 2005 PT Cruiser convertible soon. (Yes, this is a Neon area, but they both use the P platform) It's a "Granny Car" so I don't know how well it was maintained. I usually change the oil and coolant when I get a car so I know when it was last done.

What year did Chrysler go with the H.O.A.T. coolant? I know my '09 sedan had it. Hopefully I'll have this car longer than the last one. It's amazing how fast a car can get for sale when there are enough $100 bills on the hood.
