Over the last several weeks I have noticed an intensifying grinding sound, like bad bearings, so I dropped by my mechanic this morning. No visible leaks, but she is going in later today for what will probably be a Water Pump replacement. It's a 99 with 92k on the OD. From what little service information information I found prior to me owing the car indicates the WP is original.
Just glad it did not fail while I was on vacation last week.
