Am getting the truck ready for a 4,000 mile roundtrip so I may be paranoid. I'm hearing an intermittent whine from the waterpump....sounds like an alternator but I'm sure it is the pump. Happens when the truck is warming up, then goes away when it gets hot. I fixed it with a shot of spray lubricant behind the pulley.
The pump is about 3 years old, Aisin, and seems is working fine. Every other pump I've had signaled its failure via the weephole. This one is dry. Is this a sign of impending doom? If so, I'll replace it before I leave but I just put in a new radiator, fan clutch, thermostat, and hoses....don't relish the idea of digging back in.
