2005 GMC Envoy Question: RATTLE
yes it could be a comp clutch does the noise go away when you remove the belt? - goodguy
Temp gage quickly reads 200 within minutes. Not overheating or signs of any leakage. Does make rattling noise. I replaced the belt tensioner and idler pulley. Still making that rattling noise.
