Engine is squiling from the front when hot I have changed the water pump but still squiling so what can it be oil pump or main bearing or maybe tensioner but as I say only does it when hot⅚
unfortunately I have just sold it so can't let it go as is, I have never had so much trouble every time I fix one problem something else goes wrong

 

i take it you checked the fan belt?

also check the bearing on the altenator pulley

i would be shocked if it was be the oil pump or main bearing
