R Black Posted December 20, 2006 Share Posted December 20, 2006 Will a TRD Sports Thermostat, put undue pressure worth worrying about on a Supra cooling system? Link to comment Share on other sites More sharing options...
Jake Posted December 20, 2006 Share Posted December 20, 2006 What is its supposed advantage over the stock thermostat? I mean, when the engine is up to operating temp the stock stat is fully open anyway, isn't it? So where's the benefit of a TRD one? Link to comment Share on other sites More sharing options...
R Black Posted December 20, 2006 Author Share Posted December 20, 2006 I Quote "Upping the valve opening pressure of the pressure regulator on the radiator cap to allow higher radiator pressure increases the boiling point of the coolant, reduces bubbles, improves cooling, and generally maximizes the cooling performance of the radiator. We increased the valve opening pressure of the TRD radiator caps to 127 kpa (1.3 kg/cm2) and 147 kpa (1.5 kg/cm2). Thus, another full-fledged design that arose from racing car development makes its appearance." Like i said i'm just quoting TRD & i see your point Link to comment Share on other sites More sharing options...

R Black Posted December 20, 2006 Author Share Posted December 20, 2006 Not alot i from where i'm sitting, unless someone cares to enlighten me Link to comment Share on other sites More sharing options...
Jake Posted December 20, 2006 Share Posted December 20, 2006 I'm even more confused now. You asked about TRD thermostats I asked a question about them You then posted a quote about TRD radiator caps I asked what the relevance was You said "not a lot" Am I missing the joke here?

Jim_1979 Posted December 20, 2006 Share Posted December 20, 2006 I had one on my mr2 turbo. The temp needle always sat a little lower on the car from the stock thermostat. As far as I was aware, it simply started to cool the car earlier than what it normally would. (if that makes any sense at all??) Link to comment Share on other sites More sharing options...
Ric Posted December 20, 2006 Share Posted December 20, 2006 yes the trd thermostat is ment to open "sooner" or at a lesser temp thus cooling the car quicker or somthing Link to comment Share on other sites More sharing options...
uk-rich Posted December 20, 2006 Share Posted December 20, 2006 trd opens at 72 deg stock is 82 deg if memory serves Link to comment Share on other sites More sharing options...
