I've got a 95, 3.0 that I cannot seem to keep from overheating. I have replaced the water pump, cap, thermostat, had the radiator cleaned and checked for leaks, and made sure that all my connections were tight. What I'm seeing now is metallic specs in the collant. I also heard some "clanking" that came from what sounded like the fan area yesterday, like possibly something in the pump may have broken. any suggestions out their would be helpful.
