Water Pump on Serpentine Kit - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**53burb** · 12-06-2005, 12:33 PM

I have a SBC with a short water pump in the standard V8 position in my Burb. If I use a serpentine kit, is it best to remove the fan shroud?? I assume the serpentine setups all use the long water pump. Is this correct?? My current setup uses a fan clutch and the fan is just inside the shroud, not half in, half out like recommended, but thats another story. Also, is it recommended to go to a 8" balancer, since the 6" balancer would not be required for the new PS pump??

If you go with a serpentine kit, you will have to switch to a reverse rotation water pump anyway. And I am almost positive mine is a long pump. (But I have electric fans, so I can't help with that part.

I found out for sure that the water pump is the long style. What about the balancer or fan shroud???

I am running a 7-blade clutch fan(reverse blades) but to do this you will need a BB fan shroud. The balancer should be fine its size has nothing to do with the pulley sizes

So the BB shroud is smaller than the SB. I was only asking about the balancer because I have to use the 6" balancer with the PS pump mount. If I do this, then I will change to a 8" balancer. How much smaller is the BB shroud than the SB???

This is the only pic I have with BB shroud with long pump SB. The fan sits half in and half out of the shroud where the fan will be almost completely inside with SB shroud.

I am considering going with a serpentine kit MAINLY due to the A/C kit I purchased and am installing. I want a clean look with it, so I need some clean bracketry with it.

This is the kit I am considering:

I also have the short water pump stock.

So if I understand correctly, I need to either go with electric fans, or go with a BB shroud?

The balancer issue would be due to the type of kit, correct?

I haven't put my kit in yet. I just got another truck, I was scared to take it apart since it is my DD. Anyways, I was going to go with a BB shroud. I think you can go with either size balancer. I wanted to change mine to an
8", I am only using the smaller one because I have to because of the PS pump. BTW, my a/c compressor mounts on the passenger side. If you want that, the early nineties trucks are like that.

My March system came with the waterpump, alternator, all pulleys, and even the A/C compressor..
It was the March Ultra Compact kit. Bought it from Jeg's.
