Scott, I don't have any first hand knowledge of the weak cooling system.Just something I've read/heard.
Upon further diagnosis, I discovered a tiny pin hole on the bottom side of one of the heater hoses; replaced both, cooling system is now operating normally. I had done the water pump, timing belt, cam seals, thermostat, and all radiator hoses a couple months ago; it was leaking around the timing cover, and the water pump pulley was slinging coolant all over the engine bay.
The a/c system is still acting weird. Definitely stuck in the on position regardless of what the a/c button is doing. I've got the compressor unplugged (from the single conductor plug near the driver side headlight) to keep it from constantly running. Even with it unplugged there though, it's still go the secondary fan on, leading me to believe that the a/c switch itself is malfunctioning. Maybe stuck closed, instead of stuck open?
