zips or phase three water pump riser

I know this riser uses a six cylinder water pump but is there a certain part number? my pump seems to move water too slow, maybe some six cylinder pumps have a different impeller depending on six cylinder engine size? help anyone? at a long light or a couple of em' the temp gauge starts to climb rapidly, then if i rev the heck out of it it drops rapidly but the light better be turnin' green! whats up. Anyone?

 

I use a 69 Nova ... no A/C water pump from Car Quest Auto.

I add a plate to the rear



But now, FlowKooler sells a 6 cylinder Chevy pump with a plate already on it ... for $68.95

Their site says

Other Special Features:
Pump can rotate in either direction
Pump is frequently used with Zip Riser set-up
Has large and small fan hub bolt patterns
Fits Chevrolet, GM applications

I also buy a GM valve made for purging the air out of the system.







But, the main thing is using the correct pulleys. Zips list the correct GM part numbers on their instructions and I have found that using something different usually does not work as well.

 

What does the plate do to improve flow?

 

They say it improves flow by as much as 30 per cent.
Which water pump ulleys are you using ???

Randy,

What top radiator hose do you use?

 

I use Gates # 20046 for the top and a Gates # 20225 for the lower one.

 

Deuce Roadster, that's a nice looking fan shroud you show in your pic. Is that custom made or available to buy somewhere? I've been following your posts on Zip risers for awhile now and pretty much decided to use one on my '31 hiboy w/sbc.

32jones, you need a smaller water pump pulley to spin it faster. Good luck

 

I've got the zips housing I use a 6 cyl chevy pump and a 6in pulley Dayco belt#15570 if you use a 5 in pulley use Dayco belt #15555 ,if you use a 32 style radiator a Gate hose #20225 will work. Hope this helps, Bob

 

It is a Walker radiator shroud made especially for the 1932 Ford radiator. They also have them for other popular models. They are available at most Hot Rod stores. I bought mine from fellow HAMBER Shane T ... @ Southern Rods and Parts.
