96 Nissan d12
I have a 96 d21 5 speed with the 2.4 motor. When I am driving home at night at work I start getting squealing from my belts and my temperature starts going up then half way home I start losing power it’s fine if I cut my lights off. I had the alternator tested and it’s good. All the belts are good but one it’s on the power steering pump. Planning on changing it in the morning when I get up. What can I do to fix all this?
