Serpentine belt upgrade?

[louied]

Look and see if anybody has the part number diagram to go for serpentine belt setup on my 87 Tbi. I already received the two brackets.The main brackets.. And understand I need to change the power steering pump.And i'm not sure about what pulleys or tensioner are required for this setup.

Thanks in advance for any info You can provide .

Water pump swap . P/s same minus pulley .

Plus fan & clutch

As far as part numbers just use an application that came with the setup you are looking to copy - I assume that a 1991 K5 application would work.

Whatever year model brackets you’re using, just use the parts for that.

Here’s a link to the swap that I did.

1987 Serpentine Swap

I recently completed a swap from a multiple V-belt/ Serp system to a 1 serpentine belt accessory drive system. This was done in an attempt to simplify the belt situation and upgrade my troublesome A/C compressor. I figured I could show what parts I used and I'm hoping others may find this info...

Vortec serpentine works also. Look for trucks with the 5.7, 5.0, or even the 4.3 V6. If your truck has the A/C compressor on the driver side the Vortec setup keeps it on the same side.

Gets even more complicated if you're trying to go AC and smog pump Otherwise most anything from the 90s will work if you aren't worried about the AC position. Reverse rotation pump/clutch/fan like others said.

You might have to change the T stat water neck if the brackets are too high up. 4.3 V6 works, mine was '92 1500 flavor. Cars work. Van is normally narrow and taller.

I prefer AC on PS - the rest of the system is on PS. A set of hoses from square body TBI attaches it.
