Water and Oil cooling systems improved by adding an oil cooler and an electric fan pulling air through the main radiator.
![]() 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.. |
