Loud screeching sound on start
I get a screeching sound when i start my van for the first time donot hear it all day . Apparently the serpentine belts needs to be lubricated. Need to know whether WD40 or soap is better. Would WD40 increase slippage if applied relative to soap?. Request inputs. Thanks
I'm not a fan of belt lube. Just replace the belt or the pulley/tensioner that is causing the noise.
Tom's right find the problem and fix it, the belt squeal is just a symptom.
