bgambino Posted October 18, 2010 Share Posted October 18, 2010 so my sons first car...96 legacy 2.2 automatic I did all kinds of stuff to get it ready..T belt, pulleys, water pump, t-stat...all OEM Temp gauge has been fine for a month...running the standard 1/2 way up the temp gauge Lately it is running 1/4 way up....heat seems warm enough (as if maybe it really IS 1/2 way -but this is hard to judge) Could it be the gauge sender? No codes thrown Where is it...what does it look like does it need teflon tape on it? would a used one from a 2.5 outback work (not sure if it has a rubber gasket on it(i would be concerned that it might not seal well if it were old) thanks guys Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 18, 2010 Share Posted October 18, 2010 They never fail. You should check the coolant cross-over temp with a temp gun - the thermostat may be sticking open. I've had this happen a lot on my parent's Ford's. All the EJ gauge senders are the same AFAIK. They are 1/8" NPT or BSPT and are on the coolant cross over toward the passenger side - real biotch to access them. GD Quote Link to comment Share on other sites More sharing options...

GD We have an infared temp gun at work for checking mold temps......but am not sure what exactly you are asking me to check and where and how to do it While t-stat is a possibility...it is a new suby t-stat (3 months old)...would seem doubtful that its bad...but still possible i guess thanks general Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 19, 2010 Share Posted October 19, 2010 Exactly - use that temp gun to check the coolant cross-over temp right behind the upper radiator hose. Should be in the 170* to 190* range once fully warm. GD Quote Link to comment Share on other sites More sharing options...
