Hi
I want to install an electric water pump to my 3rd gen. It will be controlled via a temp sensor in the block that controlls pump speed. The instructions say remove the thermostat from the car. I cant get my head around the consequences of this. If the thermostat is removed how will the coolant flow? Will some go back through the engine and rad instead of just the rad?
Can someone enlighten me?
Thanks

 

anyone?

 

There's a hole that the thermostat fills when the engine is hot. You have to block this off, either partially, or entirely (depending on how the EWP works)

 

since all of the electric waterpumps i've seen remove the entire factory pump housing.... i've wondered the same thing. I've been toying with the idea of a Mocal Oil T-stat like used with most aftermarket oil cooler kits.

yes? no? maybe?......... any ideas??


Also.... which EWP are you using??

i am looking to build an EWP set-up. i know Mezier Enteprises makes an EWP block adapter, but it does not allow for the coolant temp sensor and the coolant level sensor. does anyone know who can provide an EWP housing water block adapter with these sensor fittings?

 

I've been looking around and haven't found anything. Seems like everyone has bungs installed in their radiator.

 

I found a site that sold block adapters that were also tapped for sensors a while back, I just can't remember where.

I'm thinking it was more of an aviation product.

 

The biggest difference between an electric and the mechanical pump is that the electric has the advantage to run at what ever flow it wants to while the mechanical has to rev with the engine. This is why you need a thermostat to control the flow through the radiator. Running an electric pump eliminates the need for a thermostat since you can just run the pump at a really slow rate to keep the temperature at the correct level.

 

removing the thermostat and running the pump to regulate flow will of course require some sort of controller for the pump with a thermo-sensor.
