Cold Temp gauge

My temp gauge is all the way at the bottom when idling, but kicks up to normal when driving. I'm noticing a very slight leak and hissing sound from a juncture where 4 hoses connect, (just under the air intake hose). Can't find what that is in my Haynes manual, and is that the issue or a thermostat prob.? Obviously, any hissing sound is not good, but before I go out in this subzero temp., I wanna' be sure to fix everything...know what I mean?

Sounds like a leak, check your hoses and make sure you have enough coolant in the system.

Thanks for the input guys....replaced the thermostat, (worst sub $10 part I've ever replaced in my life), still having the issue. I've been told that the Ranger's have an inheritant problem with the temp. sending unit.....it was only 7$ at O'Reilly's, so I bought one.........now I just gotta find where the heck it's located at.

ok, based on the threads posted, and the Haynes manual, the sensor is located just above the oil sensor. There's nothing there, just a rusty threaded hole where it might have gone. I've got a manual transmission, is it in a different spot for that engine?

on my 2.3 its right above the oil filter, its kinda hard to see and a pain in the reach and take it out, just make sure you drain the coolant before hand or you will be taking a bath, lol,
