Water Pumps

The water pump is generic 351-C, but there are two basic types depending on whether it has the warm-up passage machined in the casting or not. The stock unit is available in iron, & aluminum as an aftermarket. Type 2 (such as Weiand) doesn't have the passage machined, which means the recirculation/warm up system is inoperable and thus any thermostat will work, not just the special (and sometimes hard-to-find) 351-C unit. Note also that other aluminum pumps can be blocked off with a pipe plug in the recirculation passage, but doing this & changing to a 160 degree thermostat will not lower engine temp to that level. A few degrees lower is about all the cooling you'll get, based on my experience. Aluminum pumps are about 6 lbs less wt and take the stock pulley. A 351-W pump will not bolt up.

I'm upgrading my hoses and belts and making the change to Evans NPG. Just wondering if the water pump is the same as other 351C's or is it Pantera specific? I'm thinking while I have everything else apart maybe I'll change it to an aluminum pump.
Thanks, Guy

I have installed a Davies-craig electric water pump into the lower radiater hose (initially to get rid of the mech water pump so as to have a flat firewall) and found that the engine ran too cool, so I had to install the optional pump contoller kit. It now runs at 160. This is a great alternative to stock pumps and works great.

Can you use this pump on a daily driver or just for a trailer queen?

a standard pantera pump will work but evans would you to over drive it by about 25%. they sell a 4" pulley for that purpose, with a cost of about $90.

The electric pump is designed for everday use and I also have fitted one to my daily driver(the pantera is used mainly for competition and is definately no trailer queen.

thanks,

I will have to look into the electric pump as an option.

Where exactly did you mount the pump?
Do you have any pics?

I no longer have the mech water pump, just some fittings on the inlet and outlet side of the water passages with the electric pump situated in the lower hose(I originally did this to get rid of the protrusion so as to fit a flat firewall as it is a right hand drive model).The link listed on the previous reply has all the info you need.The best thing about the pump is that is was developed and built in Australia( I'm a bit biased).

Rabbit:Where on the car did you mount the pump? Also,How much does it cost?
Thanks

Please excuse my ignorance as I am new to the Pantera world. Did you actually remove the mechanical water pump from the engine, disable the impeller, or just bypass the w/p pulley? Either way pictures are worth a thousand words so if you could take and post some I am sure you would help people understand how this fits (works) on a Pantera a lot better.

I cut the nose off a stock Waterpump,rmoved the internals, and welded a flat plate across the front so as I just had the inlet and outlet pipes. I then just mounted the electric pump in the lower hose.
I will take some photos this week and post them.

Thanks I would definately appreciate pictures.

Any news of this? I would still love to see the pictures.
Thanks,

I noticed in the link above for the EWP Unit that there is also a dash mounted switch to control rate of flow. Seems that this setup would take care of it being too cold at times.

There are at least 2 electric pumps made in the US that are bolt on full time relacements for the belt driven pump. You can see them at:
