Tach worked again right away. However, on my way to work this morning, I noticed that when I accelerate at idle or from a complete stop, the temp gauge spikes to 3/4 of the way up, then comes down. This is opposed to before when I would overheat at idle in hot weather. I had previously concluded that I need a new radiator. However, could this new problem be related to the condition of the belt? Did it stretch and when I gun it cause the belt to slip? The belt needs replacement but I didnt feel like getting a cheap one at Discount Auto Parts because the numbers didnt match. Any thoughts?   Paul T.

In spite of the many times I have removed and replaced belts on these vehicles, I ALWAYS have to refer to my diagram. I can't decide if I should have it tattooed on my wrist, or just make a stencil and spray paint it on every wall of the shop! Peace, Paul   Jorge P.

Everybody makes them. Same belt as on some Dodge pick-up trucks. Peace, Paul   Jorge P.

Battery hydrometer on the acdelco battery was dark indicating it needed a charge. I guess I am charging the battery first, then replacing the belt with a new one I just bought. Hope its the belt/belt install. If not I will check the alternator connection etc. Any thoughts?   Jorge P.

Seems the rebuilt alternator isnt working. The dash and headlights get brighter when i accelerate. The real diagnosis will be tommorrow when I head to work.Any leads in case I cant get the rebuilt working right?   Jorge P.
