			Noted seepage from drivers side, lower corner of radiator last time I had it on lift.  Changed out water pump, thermostat and radiator for prevetime maintenace this past w/e.  It was about a 6 hour job for me.

			247,000 miles and I started hearing a little cold start chain rattle.  Replaced the timing chain tensioners this morning.  Rattle should be resolved once I try starting in am.  The old tensioners were shot with the #2 bank not even extending out all the way anymore.
