Common engine problems 2001 4.3?

Hey guys, I'm new to the forum and new to my 2001 ZR2 with 83K on the clock. I'm just wondering what common problems I should look for or keep and eye out for??

Make sure your rad overflow tank stays full of Dex-Cool.

Otherwise, regular maintenance as listed in the owners manual.

If you have specific questions post away.

EGR valves are a very common problem with the 4.3 liter engine. Carbon deposits from the engine get in them and causes them to stick open. I would recommend doing a seafoam treatment every once in a while.
