Rattle from engine, loss of coolant, burning smell?

[vman]

Ditto here. I had a rattling sound (started 2 days ago, barely noticeable but by next day on start up, it sounded horrible). I didn't lose coolant but my other symptoms were similar to the orginal poster.

I have 92k miles, cost to replace pump, tensioners, rollers and belts =$1460. I did not have my 90k servive done, the mechanic said the service would have disclosed the pending water pump problem, FWIW.
