The thermostat should maintain 195 degrees, + or - 5 degrees.
It should have a 195 degree thermostat.
Remove the tail gate then replace water temperature sensor.
The temp gauge should read ambient temp when cold and top off at 200 degrees F when fully warmed up.
195 F
Didn't have an air temp sensor in 92. Came out in 93.
The coolant temp sensor on a 2003 Chevy S10 V6 is located on the front of the intake manifold. To replace simply unscrew the old sensor and screw on the new one.
It should be located along side of the thermostat housing. The electrical plug attached should have 2 wires.
A bad engine temp sensor can do that.
An S10 is the same as a Chevy S10.
Should be two. One for the temp gauge (located between cylinders 3 & 5) and the other (located close to the thermostat housing) for the ECM to monitor.
If it has a 4.3L engine the temp sensor is located next to the thermostat housing.
Neither, I believe it's electric.
