[QUOTE="astroboy, post: 375839, member: 4527"] Nissan 300ZX thermostat opens at 76C NISMO thermostat opens at 62C Quoted from: [url]http://en.wikipedia.org/wiki/Thermostat[/url] [COLOR="DarkRed"]A thermostat is used in internal combustion engines to maintain the engine at its optimum operating temperature by regulating the flow of coolant to an external heat sink, usually an air cooled radiator. This type of thermostat operates mechanically. It makes use of a wax pellet inside a sealed chamber. The wax is solid at low temperatures but as the engine heats up the wax melts and expands. The sealed chamber has an expansion provision that operates a rod which opens a valve when the operating temperature is exceeded. The operating temperature is fixed, but is determined by the specific composition of the wax, so thermostats of this type are available to maintain different temperatures, typically in the [B]range of 70 to 90°C[/B] (160 to 200°F). [B]Modern engines run hot[/B], that is, over 80°C (180°F), in order to run more efficiently and to reduce the emission of pollutants. [/COLOR] Just to prove a point, I was scanning the N46B20 parts catalog for a Malaysia CKD E90 2007 and surprising was shown this: [url]http://bmwfans.info/parts/catalog/E90/Sedan/Malaysia/320i-N46/RHD/N/2007/july/browse/engine/cooling_system_water_hoses/[/url] [IMG]http://static.bmwfans.info/images/epc/MTI2MDc5X3A=.png[/IMG] But I'm running an electric on-demand water pump, do I need a thermostat? for what :confused: Moments later... This is more like it.. from N52.. [IMG]http://static.bmwfans.info/images/epc/MTU5NjI3X3A=.png[/IMG] Item 2 is a thermostat 11 53 7 549 476, USD$126.31 Number 5 and 6 are both electric socket to POWER the water pump!.. :rock: still there's a thermostat.. :( but tak tau buka at what temperature le.. :( [/QUOTE]
