On the coolant overflow bottle that in on the passenger side of the engine.
What type of coolant sensor? The below answer is for the coolant LEVEL sensor. The coolant TEMPERATURE sensor on my vehicle is located just next to the thermostat housing. On the front top center area of the engine just behind the radiator. Follow the coolant hoses if you have trouble. On my 1995 Jeep Grand Cherokee the sensor is located on the top of the plastic coolant reservoir tank. Look for a small (2-wire?) electrical connector.
Under hood, center, upper engine area, mounted in driver side of water outlet
sensor is located on coolant housing at engine front
Low coolant or bad sensor
The engine coolant temperature sensor is the sensor that is screwed into the thermostat housing on the top front of the engine.
There are two, and they are located on the side of the block and the other is in the coolant tank. Both are under $30 each at Schuck's/Checker's/Kragen/O' Reilly's.
The cam sensor should be located underneathe your distributor cap. That is the placement on my 98 Grand Cherokee and it should be located there as well on yours.
sensor is in the plastic reserve on the float.
It does not have a mass airflow sensor.
Don't worry about it those screens are all faulty & blink coolant temp sensor.
if it is a 96 like mine it is on the top of the coolant resovoir. it is rounnd and has an electrical connector attached to it
Not sure if this helps, but the book I have on my 1996 Jeep Grand Cherokee says that their are 2 of these sensors, I have not had the time to look for the second one. I have the same problem.
