The exact temp is what I'm really interested in, because that will dictate whether or not the thermostat is, or should be, open. If it's not that high, running cool like that could mean other things. If it is to the temp that opens the tstat, then you've simply got an efficient radiator, or a very inaccurate gauge.

Are your hoses hot and pressurized?

Consult cable + laptop + software;
Or ecu display such as techtom mdm, cmx, or nisdatascan, or ecutalk.
I use this one:
ECUTalk - Consult LCD Display

im gonna post up the part#'s of the sensors

also does anyone know what else connects to that harness ? like is there a ground off the harness? the harness im talkin about is the harness which is attached to water temp sensor an meter sensor...

Temp Goes To Middle On An Incline.. Like If Im Goin Up A Hill..

How Does That Relate To Electrical If There Is No Short Or Exposed Wire?

Does An Incline Or Hill Cause Stress On Alternator..

uhhhhhh sounds like you might need to add coolant, or atleast get all the air out..


heres my reasoning..

the coolant sensors are up fairly high on the engine, plus they're in the back by the firewall.. when you start going up hill the coolant would find its way to the sensor.. kinda like if you take a bottle thats lets say half full for example.. then lean it back at an angle.. see what the water does??

anyway i could be as far from the truth as possible but i dont know, its worth a shot.. an in my mind makes sense..

That makes perfect sense. However, I have seen more often that a coolant sensor being not covered by coolant will read hotter than normal. But, logically there could be circumstances that may cause it to read lower than normal. It's definitely worth looking in to.

It's also worth looking in to whether or not the sensor itself is still good. It may have a loose internal connection or the thermistor may not be fully secured, causing resistance variances at different angles.
