Took the truck in for examination week of Aug 4. They found water pump leaking. While in there, they also replaced the thermostat and the A/C belt. No more leaks.

But, by the same token, check and see which casting number of heads you have; if you have the 706s, keep an eye on the coolant level just the same...mine took ten years to manifest themselves.

  So, GM will sell this thing for 60% higher than it's actually worth, and those blinded by shiny things and comfy seats will buy them up in droves only to be disappointed that either the engine failure modes haven't been corrected, or, that new failure modes were introduced. After 5 years the sheer complexity and cost of repairs to the various systems will render the truck "unfixable", and thousands will head to the crusher while some people will be left owing THOUSANDS on the note. Happy now? There is no room to put, "SOLD", in my signature ... and if I edit it I lose all the other vehicles I have listed, so the Silverado will stay there until the forum changes the way that posts. I also have a few other vehicles that I can't fit there, so it's not accurate anyway. Besides that, I don't much give a ****.

  If you have air in your oil pump, your engine is on borrowed time. That should NOT happen EVER. What that sounds like to me is the starter spooling down from a high RPM coupled with the drive gear retracting back into the starter. Stuff like this they used to take the time to engineer out of components ... but these days that kind of quality is a 20th century relic, so this is what you get. The sound reminds me of those toy cars I had as a kid that had a flywheel and spring inside - you would rev them up by pushing them along the floor until you heard that flywheel spinning at a high RPM, then you could let the car go and it would shoot across the floor at 20 MPH, launch of jumps, smash into furniture and walls. There was a point where you could get the RPM of that flywheel so high that it would go FAR out of balance. The whole car would make that exact sound, and the high RPM would bleed off SUPER fast due to the imbalance. Sounds exactly like what is going on with the starter. Just my educated guess anyway.
