Where is the coolant temperature sensor located on a 1986 Ford 460 engine?

The coolant temperature sensor (CTS) on a 1986 Ford 460 engine is typically located in the intake manifold. It's usually a single-wire sensor screwed into the manifold itself. However, the *exact* location can vary slightly depending on the specific casting of the intake manifold.

To be certain, you'll need to:

1. Consult a repair manual: A shop manual specific to your 1986 Ford vehicle with the 460 engine will show you a diagram of the engine bay and pinpoint the CTS location.

2. Visually inspect the intake manifold: Look for a sensor with a single wire connected to it, usually near the thermostat housing or in a relatively central location on the manifold. It's often a small, cylindrical sensor.

3. Trace the wire: If you can locate the wire leading to the engine control module (ECM), you can often trace it back to the sensor.

Remember to disconnect the negative battery cable before working on any electrical components.
