Introduction

This workguide is a basic walkthrough of a full cooling system upgrade using Davies, Craig products from stock on my wifes HR.
The products used are:
- Generation 3 Electric Water Pump
- Digital Pump Controller
- 2x 12" Thermatic Fans
- 1x 14" Thermatic Fan
- 1x Thermatic Switch

The Electric Water Pump will be used (as with my car) to completely replace the standard water pump in the system. The 2x 12" Thermatic Fans will go behind the radiator and the 14" Thermatic Fan infront of it (behind the grill). I am only demonstrating these fans will fit however and would recommend either the use of 2x12" or 1x14" fan infront of the radiator OR 2x12" fans infront and 2x12" fans behind simply for ease of installation.

Packaging

Everything was delivered straight from Davies, Craig without a problem and no damage was visible on any of the products or even to their boxes. Davies, Craig products are well packaged to protect the product and it would take a fair bit of force to damage anything.

The items for the upgrade

Here I am displaying the items which will be used in this upgrade. On the back row we have the three thermatic fans (2x12" and 1x14") and on the front from the left we have the Digital Pump Controller (used to control the pump), Electric Water Pump and Thermatic Switch (used for fan switching).

EWP Controller Kit contents and write-up

The new digital EWP Controller kit is fairly impressive in its own right. If you want to compare this controller to the previous generation controller then have a look inside my previous EWP installation guide. The old controller used a small screw to adjust the target temperature for the system whereas this one uses a very informative LED display to not only show you what temperature your system is aiming to maintain but also what temperature your fluid is currently at.

Setting of the controller is done through the use of a single "Set" button. The display contains five LEDs for a temperature range of 75 to 90 degrees as well as 3 more LEDs displaying controller power state, pump state and a warning light.

This controller also has an in-built "running on" feature, allowing the pump to run for an extra 2 minutes after the car is shut down to remove heat soak from your engine.
