Oil breaks down rapidly when subject to too high a temp and closely machined mechanical parts experience boundary lubrication - that is metal to metal contact. Sometimes you will have extra wires that are not connected. Order online at Screwfix.com. The role of the thermostat is to maintain the circulation of water inside of the engine block when the engine is started in a cold state in a manner that the normal functioning temperature of the engine is attended quickly .
