Having done an electric conversion myself and having seen the results of a conversion with parts from "no name" suppliers, I advise you to make damn sure that what you buy is the best available.

Several electric fan makers now source from TYK, which has a rep for CRAP but has placed themselves as the "low priced" alternative to the majors and now makes for several of them.

I went thru issues with their "OEM" replacements for a Chrysler I owned and know of others who have had the same issues with "name brand" electric fans only to find on disassembly that the guts were TYK made. Sub par wiring, connectors and plain garbage motors.

As to pumps, the same advice applies. In addition consider an extra temp sensor placed in the system where a pump failure will become evident before it becomes a head warping issue.
