Introduction

Water and Oil cooling systems improved by adding an oil cooler and an electric fan pulling air through the main radiator.

Re-build of the cooling system with electric fan

Original radiator failed so system upgraded with wide radiator and adjustable thermostat.

Support frame bolted to chassis at an angle to give room for electric fan.

Radiator lowered in support frame and set at angle to get clearance to bonnet.

Side view showing angled support / radiator and cut down side panel.

Oil cooler bolted in front and below radiator.

Finished job with adjustable thermostat fitted for better control.

 
Below is the original upgrade to standard radiator.... now removed.
 

Relay added to circuit to protect the thermostat from the fan. Relay type Durite 0-727-12 used.

Radiator moved from central position on side brackets to just 4 fixings (2 each side) at the front of the brackets.

Support frame bent slightly to lean further forwards - new side panels needed (in fabrication - watch this space).

Reconditioned radiator fitted with pre-installed thermostat. Brackets made to mount fan to side brackets between radiator and water pump - budget pull fan purchased from S.V.C.

Wiring with fuse. Earth connected to bond at clutch housing.

Bonnet just clears top of rad. New hoses sourced from suppliers on ebay - top hose - Nissan 180 (21501-U9600) shortened both ends and bottom hose - Vauxhall Victor (RH1142).

Just enough room with viscous fan removed.

Wiring diagram used on my car, could split live wires with 2 fuses and have the thermostat side to a switched power from ignition.

 
Oil cooler added for long motorway runs

Mocal sandwich plate type SP1X with 5/8"UNF inverted extension screw fitted to engine. Parts from Think Automotive Ltd.

Pipes passed through suspension and under water radiator.

Brackets made to fit oil radiator to existing bolt positions.

Oil radiator fitted to base of water radiator.

System and pipes filled with oil, then pipes connected prior to start up and pressure test..
