Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Coolant Temperature Sensor
The coolant sensor is located in the cylinder head of 6-cylinder engines and in the intake manifold of most V8 engines. The 318" 2-barrel engine has the coolant temperature switch in the charge temperature switch location on the intake manifold. The coolant sensor informs the computer when the engine has reached a predetermined temperature, so that proper adjustment can be made in the air/fuel ratio. It also prevents changes until such temperature is reached.
