Electric Water Pump Install

You can not retain the heater function with that pump, the two lower ports are so you can run the hose out either side. Meziere makes a pump that retains heater funtion WP311S, a little more money then the CSR but much nicer IMO.

If you need one of those I have a customer that went a different route and wants to sell his, its brand new never used in the original box.

I never need a heater here so i plugged the port on the intake and capped off the bypass on the water neck.

Thats correct, Ive been creative over the years removing the pipe nipple from the water pumps and tapping and plugging them for a cleaner look, Ive also brazed caps on them..otherwise they sell these rubber caps in the HELP section at most parts stores that work just fine. Just keep an eye on it overtime for cracks.

The Meziere pump is black, I believe you would have to change the timing cover to use it if your using an early style front cover.

thats where i got it from and yes it did crack over time.I worked for Ford for a while and kept a bunch of caps that came on the replacement water pumps and used one of those.Doesnt crack like the rubber did.

Was it from a 289 or is it 302 based? Can you post a pic....

Look up your cover's part number to be sure.
