I have a 2021 Silverado Z71 1500 RST with a 5.3L with just over 25,000 miles on it. The water pump pulley fell off. It started with a little chirp noise I thought was the idle pulley. I was surprised to see that there's no tension pulley. 23 miles later the water pump pulley came off. Has this happen to anyone else? Is this press in or screwed in.
