Desperately Need Help!!

Hello,

If someone can provide me any information about water pumps used for a 1991 Toyota Corolla (1587cc 4F-AE), I would really appreciate. Such information as power rating and volumetric flow rate of the coolant would be preferred.

Thanks in advance.

It seems no one can help me with this. How about the typical pressure or head change across the pump, blade width, diameter......etc. Anything would be useful...please help me out.

have you tried Toyota engineering?

I've tried calling Toyota, but it seems they don't carry information for a model as old as 91.
