My 2000 did it --sounded like a diesel for about 30-45 seconds. Once running more then 2-3 minuts, it was gone. Sold the truck after 185,000 miles--still runs like a raped ape!! My 2002 does it too---other then the noise, no issues. Even my 2000 Tahoe did it after around 60K miles. Just a pita, nothing to worry about. Do watch for water pump gasket leaks and A/C--heater air flow issues on the passs side~~. Bigger pita!!
