cold start up high pitch squealing noise from engine
on cold days especially when I start the truck it will squeal with accordance to the engine,
when I speed up the squeal gets higher pitched. after my truck heats up to its regular
temp the noise will fade away. anyone know how to fix this noise?
Check the fan clutch. That's what it sounds like to me. It may need to be replaced. They cost $50-60. I've never tried to take one apart or fix one, I just replace it.
Belt squeal because it's slipping would be my guess. The belt tensioner is probably wearing out and not putting the tension like it used to and the moisture in the air when it's cold is making it slip
Yep belt squeal, if it has just started to do this check the belt for glazing If it is glazed then replace it, if not then check the belt tensioner for proper tension, if that checks good then check the fan clutch with the engine warm, the fan should freewheel, if that checks good then have the battery and charging system tested, your battery maybe getting weak causing the alternator to go full field on start up causing the belt to slip even though it looks good.
