Every time I start the truck the belts squeal like a pig till it gets warmed up. VERY ANNOYING!!! What can cause this? Also I was going to put in aluminum pulleys in, but the set I found says it's for a KEYWAY power steering pump, what is that?

What year is yours?

And the Keyway is on the shaft of the power steering pump, if your has a nut that holds the pully on then it has a keyway.

it is a 78, no A/C. I wanted to post pictures to your post "how many 2wd blazers do we have", but i have no camera.

try tighting your belt or replace them if they have cracks in them.

Try tightening your belts. You could diagnose further by removing belts one by one, starting the truck briefly, to find which one is the culprit. I only have one belt, and it squeals when the weather is cold. I think mine is mainly due to the p/s pump starting to go bad.

squirt wd40 on the belts( bit should work)
