Where to Locate the Temperature Sensor on a 1994 Chevy S-10 4.3

The 1994 Chevrolet S-10 saw many styling changes from the previous, first-generation lineup. Two optional 4.3-liter Vortec V-6 engines were available for the 1994 model year, along with a standard 2.2-liter four-cylinder. All engine configurations utilize a coolant temperature sensor, which aids the onboard computer and corresponding dashboard gauge with vital information concerning the engine's temperature. A malfunctioning coolant temperature sensor will cause erratic gauge readings as well as provide your vehicle's computer with incorrect temperature information.
