Great truck, absolutely everything works! This V6 has a pump & sending unit in the tank, access panel on top. Ours was reading only in the middle. We cleaned the varestat with carb cleaner and scotchbright as well as the wiper. It works good as new, the tank is 20 gallons not 15 as listed in many manuals. We also installed a bull bar as the front end is weak.
V6 runs cool in our hot desert climate, and is built like a tank, except for the front end, which we beefed up with a bull bar.
Put in a bull bar, not a brush guard to protect front end, so you can drive after hitting something or being in a accident.
