jerryrigginson Posted January 24, 2006 Share Posted January 24, 2006 On most cars the thermostat is in the inlet to the engines coolant pipe. I was just wanting to see how hard it is to change the thermostat on an sc400 and where the thermostat is located ie which pipe to take off. I have only done a thermostat change on a toyota tacoma before so i wanna know what i am getting into. I am not taking it to a dealer for a part that costs 15 dollars to be changed if i dont absolutely have to. Quote Link to comment Share on other sites More sharing options...
SirSam Posted January 24, 2006 Share Posted January 24, 2006 I have not done this personally on the SC, but after looking at it. Thermostat should be right in the inlet housing & usually just requires the 2 bolts to be taken off and remove thermostat. Quote Link to comment Share on other sites More sharing options...
alicias Posted January 25, 2006 Share Posted January 25, 2006 i'm no mechanic and changed mine -- it was easy. make sure you get the gasket. there are instructions with pictures somewhere in this forum and they were very helpful. Quote Link to comment Share on other sites More sharing options...

GL123 Posted January 2, 2007 Share Posted January 2, 2007 I just changed the thermostat on my 92 SC400. Here are some additional tips: - The drain !Removed! is on the back of the radiator and is accessible from the oil filter access hole in the bottom engine panel. - Before installing the thermostat, insert the thermostat into the inner groove of the rubber seal.

95_SC400 Posted January 2, 2007 Share Posted January 2, 2007 Hi, This brings up a question i've had for a while. Has anybody tried the TRD thermostat? It claims a 10 - 15 degree reduction in the valve temperature. Anybody think its worth it? Pros? Cons? http://trdparts.jp/english/parts_thermostat.html Quote Link to comment Share on other sites More sharing options...
