Davies Craig Coyote Adapter Instructions

04/06/2019 12:00AM

One of the greatest strengths that Davies Craig has is in its straight forward instructions for fitting equipment. Our new Coyote adapter kit is no different, and we recognize that those with a Coyote powered Mustang will like to ensure an easy installation.

Davies Craig use a step by step procedure, and here is how it works for the Coyote Adapter kit. No step, however seemingly silly, has been left out.

Step One:            Remove the radiator cap then disconnect the bottom radiator hose to drain the coolant from both the radiator and engine into a clean tray. If the coolant is clean and free of foreign matter it may be reused. Retain the bottom radiator hose, you may require a section of this hose to complete your EWP® Coyote conversion.

Step Two:            Loosen appropriate water pump hardware and remove drive belt. Disconnect heater return hose and remove the mechancial water pump from the Engine Block.

Step Three:        Retain the bolts from the detached mechanical water pump as these will be required to attach your Coyote EWP® Adaptor Plate. Clean the surface of the engine block to ensure it’s free of the old gasket and any grime and coolant.

Step Four:     Pre-Assembly – take the Coyote EWP® Adaptor Plate and place the small O-Ring provided over the surface of the inlet. Secure the 38mm (1½”) Straight Adaptor onto the Coyote Adaptor Plate with the 6 x M5 Screws provided. When mounting the Straight Adaptor to the plate ensure the O-Ring is properly positioned. Take the large O-Ring and place in the groove located in the rear of the Adaptor Plate. Find a clean pair of gloves and use some quality cleaning products to ensure the front of the engine block is as clean as possible, especially around the area where the gasket will sit. This is essential to ensure a good, tight, fit for the new parts, and minimize dirt entering the engine’s internals.

Step Five:    Slide the Coyote EWP® Adaptor Plate Assembly into the open profile on the engine block where the mechanical water pump was positioned, ensuring the large O-Ring sits in its groove and mounting holes align with those on the engine block. Secure plate in place with existing hardware.

Step Six:  Secure the 90° Hose to the 38mm (1½”) Straight Adaptor with large hose clamp provided. Then slide the In-Line Adaptor into the bottom end of the same hose and secure with large hose clamp supplied. Then secure the bottom radiator hose (if serviceable) to the In-Line Adaptor with a large hose clamp supplied. Secure but do not fully tighten. If required, place one 3mm rubber sleeve supplied on each end of the In-Line Adaptor. Do not tighten.

Step Seven:   Pre-assemble the Heater Return Adaptor to the EWP® inlet using Teflon tape to prevent any possibility of leaking. Align the EWP® with the bottom radiator outlet. Ensure your EWP® is located as low as possible relative to the bottom of the Radiator outlet to assist with bleeding trapped air. Use a small portion of the bottom radiator hose to secure the EWP® to the radiator outet, (the remainder of your current bottom radiator hose may be suitable for this purpose). Connect the radiator hose with a large hose clamp (supplied) to the EWP® inlet. Then fit the other end to the bottom radiator outlet with a large hose clamp (supplied).

Step Eight:          Remove existing Heater Return “T” piece from Mechanical Water Pump. Connect this piece to the Heater Return Adaptor using heater hose and clamp, (supplied).

Step Nine:    Connect the second 90° Hose (supplied) to the engine coolant outlet. Join the 90° Hose to the top radiator hose using the second In-Line Adaptor Nylon and hose clamps (supplied). Fit the new belt (supplied). Take the other 90 degree radiator hose and connect and clamp to the 90 degree hose on the adapter plate. 

Step Ten:   Once you are satisfied with the initial assembly and alignment of your EWP® and EWP® Header-Adaptor Kit conversion, proceed with final assembly ensuring all hose clamps, screws and bolts are sufficiently tightened to prevent   leaks.    Be careful not to over-tighten. Place the new Davies Craig Electric Water Pump next to the open end of the radiator hose, ensure a clamp is on that open end, and push the EWP’s connecting plug into the hose. Clamp and allow for adjustment if necessary. It’s here that the Davies Craig Electric Water Pump then has the ½ inch heater hose plugged into the front top hose connection. This is the heater return hose adapter.  Again clamp and allow for adjustment.

Step Eleven:      Follow the LCD EWP®/Fan Digital Controller installation instructions to complete this part of the EWP® conversion. Using the T shaped heater return plug from the existing hardware, refit that to the appropriate hoses.

Step Twelve:   Refill the radiator but not replace the radiator cap at this point. Then start the engine. Your EWP® and EWP®/Fan Digital Controller combination will commence its pre-programmed ‘test’ mode and operate the EWP at full speed for 5-10 seconds. Turn on the vehicle’s heater (if applicable) to the maximum setting. Run the engine for approx. 10 minutes while carefully monitoring engine temperature. Top up coolant level as required. Switch off engine. If you are satisfied your cooling system is completely free of air, replace the radiator cap. Restart engine, run up to operating temperature checking all fittings are secure and observe for any leaks. Switch off engine and re-torque any fittings and hose clamps if required. Check coolant flow in the heater lines. N.B. If you find the heater is not functioning correctly, you may be required to fit an EBP15 Electric Booster Pump, (part #9001) to the heater line.

Mount and clamp the bottom radiator hose to the front of the Davies Craig EWP which is the section that also holds the ½ inch heater hose. Finish the installation by connecting the Davies Craig LCD EWP/Fan Digital Controller to the Electric Water Pump and mount the EWP following the instruction sheet. Check all mounting bolts and clamps, and tighten as required.

Final Step:           ‘Road test’ the vehicle, running the engine up to operating temperature. Again, turn the heater full-on to assist purging of all air from the cooling system. Allow engine to cool down, check coolant level again, topping up if required. Please repeat the above process until you are satisfied your engine’s cooling system is totally free of air, all hose clamps and hex cap screws are tightened satisfactorily to avoid any leaks. You should check your cooling system thoroughly after 20 hours of operation.
