How do I know if my thermostat is working?
1997 Mazda B4000; 4.0 L V6; 5-speed, 4WD; I bought it used in January; have put only 1,000 miles on it since.Drive the truck to/from work, 1.5 miles, engine never really warms up so I don't know what a normal temp gauge reading is.
Yesterday drove 100 miles one way to join 160,000 of my closest friends at the Bristol race. Up and back them temp gauge never went above 1/4 to 1/3 scale. I am accustomed to temp gauge running at half scale or slightly higher.
Does this indicate thermostat is bad?
How do I check the thermostat other than watching the temp gauge?
Thanks.
