EWP Electric Water Pump Kit for RB
RB25, RB26 RB30 EWP - electric water pump kit.
The kit comes complete with everything needed to mount and run the electric water pump.
This kit includes the Davies Craig control box (when option is selected) , is a stand alone unit that does not require connecting to the engines ECU, allowing the control box complete control over the coolant temperature,
The control box is powered directly from the battery, allowing the unit to control the water pump and fans while the engine is switched off. This allows you to turn the engine off and go do other duties, allowing the control box to do what it does best, this strategy allows you to restart at the optimal engine temp. No more over heating issues!
Davies Craig have a preset control program in the unit, testing has shown to work very well straight out of the box, however, should your engine package require a different coolant temperature strategy, the unit is configurable to target different temps and setups.
The pump only draws around 10 amps of current,
You can trigger the pump from your ecu, via a relay, however the benefits of the "key off" function is often lost, depending your ecu choice. This full kit with the controller works very well with stock ecu's, or ecu's with limited out channels.
Angled pump mounts are available for RB25 and RB26 (purple unit in pics) engines, as some aftermarket intake manifolds with large plenum barrels may cause fitment issues against the top of the pump.
Each EWP kit is supplied with a 1/8npt bleed nipple, some engines require these to bleed air from the pump on initial coolant fill, you will need to drill/tap the bleeder into the flat of the top outlet of the pump.
* A shorter belt is required. With LS alt, around 4PK-760
* Not all the parts in the kit are represented in the pics
* Due to the relocation of the water pump, it is advised that the heater hose that connects to the back of the thermostat is plumbed to the top radiator hose to emulate stock flow characteristics.
* Custom colours can be ordered, Like all awesome things, it takes a little time.
* Replaces stock mechanical water pump - 21010-21U26 / 21010-24U27 / 21010-RHR30
