Oil Cooler Thermostat (screw on connectors) - RX2039

Oil Cooler Thermostat (screw on connectors) - RX2039
Oil thermostat with 1/2" BSP screw fit connectors - 80ºC opening temperature. Use inline with oil cooler kit and screw fit hoses.

Engine oil has an optimum operating temperature designed to maximise lubrication whilst maintaining good oil pressure. Oil coolers help maintain this balance during the summer months but can over cool the oil when the weather starts to get cold. A thermostat will ensure that this doesn't happen.

With an oil thermostat installed, the initial volume of oil warming up to temperature is reduced (ie. the volume of oil within the cooler is not circulated at this time) allowing the engine to reach operating temperature more quickly contributing to a more efficient engine. Once that oil exceeds 80ºC the thermostat opens and gradually introduces the cooler oil as required, closing off if the oil cools to below 80ºC. The temperature threshold of 80ºC is not coincidental as this is the temperature required to evaporate off contaminants which form and concentrate within the engine oil during the combustion process. If these contaminants are not "burnt off" they can cause sludge to form in the crankcase and alter the oil sufficiently enough to cause a chemical attack on the precious white metal crankshaft bearings. This is a common symptom exhibited by engines that cover regular, short journeys.

The thermostat is constructed with lightweight materials allowing it to be easily supported by the rubber hoses.
