That vehicle doesn't have a coolant temp sensor. What I mean is, that there is no sensor that makes direct contact with the coolant. It has a CHT, Cylinder Head Temp sensor. The PCM calculates how hot the coolant must be, based on how hot the cly head is. On a 4.2 liter, it is located at the rear of the driver's side cyl head, all the way around in the back. On a 4.6 and a 5.4, it is located in the driver's cyl head inside the valley area, toward the front, just far enough under the intake manifold to make it agrivating. You will probably end up lifting the intake up to get to it if you are working on a 4.6 or a 5.4.
sould be on the manifold
The coolant sensor moniters the coolant temperature. A faulty thermostat could cause the engine to run cool.
In front of the intake manifold on the coolant tube
The 1992 Ford F2 50 pickup truck 5.8 liter engine coolant temperature sensor can be found on the top of the engine. The coolant temperature sensor will be near the intake manifold.
Could be the coolant temperature sensor.
on the front of the intake on left side when standing in front of truck.
Check your coolant level. If its too low the sensor won't read the temperature of your coolant.
coolant temperature sensor is the right of the coolant outlet line on the top of the engine when looking at while standing in front of the truck. it has a black two prong clip attached to the sensor. the oil temp switch is to the left of the coolant outlet line. it has a single black wire coming off of it.
It is on the right rear side of the drivers side head. BESIDE the BACK spark plug.
There are two on a 1994 Ram, one on each side of the thermostat housing. The one with one wire is for the temp gauge. The sensor with two wires is for the computer.
The coolant temp sensor for the gauge is located near the front passenger side of the engine near the thermostat. It will be pointing slightly down and to the front of the truck. Will have a single yellow wire attached. The coolant temperature sensor for the ECU is bolted into the intake manifold in front of the carb. It will have a green 2 pin molded body. A 3rd sensor is located in the bottom of the radiator, this turns on the Carburetor PTC heater when the coolant temperature is below 60 deg F. Kyrasis6 Owner of Mazdatruckin.com
Engine coolant Temperature ( ECT ) sensor does not meet minimum thermostat regulating temperature. Need to replace ECT sensor. Make sure engine is COLD before changing. The sensor is on the right head back beside the last spark plug.
