usually on most vehicles it's close to the water outlet housing where the upper radiator hose meets the motor. Actually, on the 1990 for ranger with the 2.3L it's on the driver side of the block, towards the back...under the intake manifold...I couldn't get a look at it from the top but you can see it from the bottom. Also, you may want to drain some water out of the radiator/block or expect to get an anti-freeze bath.
Which engine do you have?
The Cylinder Head Temperature (CHT) sensor for the 2.3L engine is located between the two center ignition coils. The Engine Coolant Temperature (ECT) sensor for the 3.0L engine is located in the intake manifold to the right of the thermostat housing. The Engine Coolant Temperature (ECT) sensor for the 4.0L engine is located in the intake manifold behind the thermostat housing.
On a 1995 Ford Ranger with a 2.3L engine, the coolant temperature sensor is located on the engine block, typically near the thermostat housing. It is usually mounted on the cylinder head or intake manifold. To access it, you may need to remove any obstructing components, and it's advisable to disconnect the battery before servicing.
The coolant temperature sensor for a 2010 Ford Ranger is typically located on the engine block, near the thermostat housing. It is usually found on the intake manifold or cylinder head, depending on the engine configuration. To access it, you may need to remove other components, so it's advisable to consult the vehicle's service manual for specific instructions.
The sensor for the heat gauge on a 1994 Ford Ranger XLT is typically located on the engine block, near the thermostat housing. It is often a threaded unit that screws directly into the engine and reads the temperature of the coolant. This sensor sends the temperature data to the gauge on the dashboard, allowing the driver to monitor the engine's operating temperature.
On a 2002 Ford Ranger with a V6 engine, the coolant temperature sensor is typically located on the engine block, near the thermostat housing. It is usually positioned on the intake manifold or cylinder head, making it accessible for wiring connections. You can identify it by its two-wire connector and the threaded body that screws into the engine. Always refer to the vehicle's service manual for precise location details and diagrams.
To change the coolant temperature sender on a 1992 Ford Ranger with a 3.0 engine, first ensure the engine is cool and disconnect the negative battery cable. Locate the coolant temperature sender on the engine block, typically near the thermostat housing. Use a wrench to unscrew the old sender and then install the new one, being careful not to overtighten. Finally, reconnect the electrical connector and the negative battery cable, and check for leaks after refilling any lost coolant.
The Engine Coolant Temperature sensor can be found near the thermostat housing or close to where the upper radiator hose attaches to the intake manifold. Good luck.
on the front, top of the engine. look near the upper coolant hose on the engine for a sensor with a couple of wires on it. There may be 2 in close proximity that look similar.
The engine coolant reservoir has a thread on cap which is the "radiator " cap for the 4 cylinder engine
on top of the engine on the hose that outlets from the pipe going to the thermostat. it has two spade terminals and is easy to access right there in the middle of the engine bay
On a 2003 Ford Ranger with a 4.0L engine, the temperature sensor, also known as the coolant temperature sensor, is typically located near the thermostat housing. It is often situated on the engine block, close to the intake manifold, or near the upper radiator hose. You can usually identify it by its electrical connector and the threaded body that screws into the engine. Be sure to check your vehicle's service manual for specific details and diagrams.
