I have been doing some research on this problem but all seem to be a bit different. The temp gauge goes up, right under normal, and falls back down to cold. Moves up a little above the C, and falls back down. The chances of it staying in the Normal range is low. The heat is like regular air, nothing warm or hot.

1997 ford ranger 2.3L

-Top hose is warm (thermostat opening = good)
-hoses going to heater core is warm (will check return hose) Some moisture around the temp sensor "T" connector. the culprit?
-heavy acceleration 3rd gives a LITTLE warmth to heat, barely noticeable.

I bought a new temp sensor, but the T connect seems to be in bad shape. Went to ford and they gave me this part number: f2tz18b402a Can anyone verify this is the T connector?
