Is the coolant sensor the same as a thermostat in a 1996 Jeep Grand Cherokee Laredo?

The coolant sensor is a device screwed into the water jacket usually in the water outlet housing near the thermostat. It will have a wire going to it, and is used to tell the computer or ECM what temperature the engine is operating at. This will allow the computer to enrichen the mixture when cold and lean it out when it warms up. The thermostat is a mechanical/thermatic device located in the water outlet housing and you cannot see it when the engine is together.It has a wax pellet inside of it that expands when hot and in turn opens a gate for water to flow through it. You have to take the housing off at the upper hose in order to see the thermostat. It doesn't have any wires going to it and is strictly for controlling the water flow through the upper radiator hose to maintain normal operating temperature so the answer is no, they are not the same, they do different things. Be aware too, that if you have an overheating problem do not just simply remove the thermostat thinking you are solving all your problems. The engine with no thermostat will always run rich, will pollute a lot, it will foul your plugs, it will lack power, your heater will never warm up, the check engine light will probably come on, it will fail the smog check if you have one where you live, the oil will run too thick for proper lubrication and, not to mention eventually over time this condition will ruin your catalytic converter. SO get the system working properly!

Where is the coolant sensor in a 2001 Jeep Grand Cherokee?
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.

Check your fuse, and your coolant temp sensor. The coolant temp sensor is more than likely the problem
Where to find the coolant censor on a 1994 jeep grand Cherokee Laredo?
There are two separate sensors that play here. the "coolant temperature sensor" and "coolant LEVEL sensor". I suggest confirming which of these was replaced, as it is very common for them to be confused. likely you will find the coolant sensor that was replaced was the one on the engine (temperature); The LEVEL sensor is mounted either in the coolant resivoir or in the radiator. Probably just need the proper sensor replaced.

How do you locate the engine coolant temperature sensor on a vehicle to replace it?
coolant temperature sensor are located where the coolant runs in the block near the thermostat housing normally the connector are on top of the sensor and the sensor itself screws in with a deep socket. The temperature sensor is usaully located where the coolant runs OUT of the engine close to thermostat housing.
