Can you shorten the water pump?

Hi all,

I want to increase my cooling capacity by installing a 16" thermo fan on a new aluminium radiator. The problem is that the space between the back of the radiator and the water pump pulley is way too small. Does anyone have a suggestion for how to solve this?

At the moment I can only think of installing an electric water pump and removing the water pump impeller/pulley and welding up the hole (I think I need to keep the water pump housing). Is there a simpler alternative?

Thanks

Leigh

I could do this, but I think that the fan will not work as well.

I think it will work better.

The Fan Motor will stay cooler for a start.

Holdenpaedia, they're the brakes Mate.

Theremo fans work fine blowing air through the radiaor, ie, in front.

You won't fit a 16" fan in front of a HR radiator. From memory the core is only 340mm high. This limits you to a 12" fan.
To fit it behind and do the best job I would replace the waterpump with an aluminium plate. Fitted to the plate would be a #20 AN fitting. This would run to a remote Davies Craig pump EWP80 would be fine. Then use the Davies Craig electronic controller to control both the pump and fan.
This is the setup (I would use EWP115 pump though) I will go to if I end up running into problems with my EH.

I am currently using two 12" Davies Craig fans in fron of the radiator. It seems to work well even with the 355.

Thanks for the feedback. Would you also fit the heater to the Al plate, or connect it elsewhere?

It's an outrunner, beats a Brush motor in both efficiency and long life too.

Yes you could. One hose to the plate and one to the lower thermostat housing.
