Thermostat & Standard Water Pump

THERM-DURA2
We have a new thermostat & housing to replace the standard Ford electronic version, this allows your cooling system to work in a more traditional way without the need for an electronic control system. When using the standard water pump the unit is a simple bolt-in replacement. Shown right on our display engine.

When using an electric water pump, this housing is ideal as an inlet into the engine; you simply remove the original thermostat & use the housing.

Thermostat & Electric Water Pump Options

When using an electric water pump, you have 2 choices on entry into the engine either from the front or the side of the engine, depending on your installation.

Front entry

THERM-DURA3K
The blanking plate shown replaces the original thermostat housing & is a neat & tidy option. It includes an o-ring to seal the engine. When using the blank, we currently modify the standard water pump to make a new lightweight entry into the engine.

WT-DURA-WTP-HS-01
We modify the original water pump and convert it to a water inlet, this is specifically designed for use with an electric water pump. The price to modify the customer's original water pump. If you do not have a pump available, please contact us for the cost of providing a base water pump. This component would normally be used in conjunction with THERM-DURA3K.

Side Entry

THERM-DURA2
If the installation when using the electric water pump suits entry into the side of the engine where the original thermostat housing would be (see standard thermostat). We would then modify the standard water pump to make a nice neat blank.

WT-DURA-WTP-HS-02
We modify the original water pump and convert to a blank, this is specifically designed for use with an electric water pump. The price to modify the customer's original water pump. If you do not have a pump available, please contact us for the cost of providing a base water pump. This component would normally be used in conjunction with THERM-DURA2.

Water Outlet

WT-DURA-3K

This new water outlet we have developed is very compact, ultra lightweight & especially designed for use with electric water pump installations. We have placed the coolant temp sensor directly into the back of the head (shown on far left picture) to give an accurate temperature reading as possible. We have found in tests over many years than when using an electric water pump we do not need hoses larger than 25mm id, this significantly reduces the amount of water carried on the car. It will accept either the Ford type coolant sensor or Bosch equivalent (our part number WTS1).

Ideal for use on Westfields, Caterhams & single seater cars.

Electric Water Pump

WT-PM5-EWP-1 Electric Water Pump kit

WT-PM5-EWP-1

Electric Water Pump suitable for 1.6L & 2.0L car engines, as used by us on our Duratec engine.

It must be controlled either by the latest MBE ECUs or a standalone Davis Craig Digital controller WT-PM5-EWP-CON-02. For more information & options

Duratec Water Rails

A Heat exchanger or Laminova (Oil/Water) has been our preference over a traditional Air/Oil cooler for many years now as it gives the following advantages;

1. Engine oil is heated when cold by the water system, meaning less wear on your engine during warm up.

2. Reduced length of oil lines as no longer need to run to the front of the car (to airflow).

3. Oil cannot be overcooled, it will match the coolant as a base line temperature.

4. Weight can be saved on the overall installation.

Most Duratec Escort installations until now are not designed to incorporate a heat exchanger, this is why SBD have carefully designed our latest water outlet around the Mk2 Escort, utilising the latest 3D CAD modelling techniques coupled with CNC machined we have produced a water manifold only 25mm deep, which brings the coolant out to the intake side of the engine allowing fitment of a heat exchanger on this side of the engine bay, keeping coolant hoses away from the exhaust side of the engine.

It is designed to be used with an electric water pump, hence no re-circulation pipe. The reason we recommend its use with electronic water pump only, is because the standard water pump and thermostat requires a recirculation pipe to take hot water from the back of the cylinder head into the back of the thermostat housing.  This water then recirculates around the engine keeping an even temperature, this water passing over the thermostat causes it to open at the appropriate temperature.  If this pipe is removed, then the thermostat cannot operate correctly causing erratic engine temperature changes as the thermostat then relies on radiated heat.  Once it begins to open, then would then be a sudden rush which would instantly cause the thermostat to close again and the cycle begins again. 

The manifold itself has provision for 1/8NPT gauge sender units, a bleed fitting and also a M12x1.5mm ECU coolant temperature sensor (not included in kit).

Oring seals are used for ease of installation and reliability.

Includes 1 x brass push on bleed valve, 2 x blanking plugs and fitting kit.
