That sensor is the one between the exhaust manifold and the catalytic converter (sensor #1). Bank 2 is the side of the engine that cylinder #1 is NOT on. Here is a diagram showing cylinder #1.


FYI, sensor #2 is the one behind (downstream) the catalytic converter.

SOURCE: cooling fan switch/or sensor

The Coolant temp Sensor is located right under the top radiator hose (on the engine side), with a little black connector!, You might have to remove th etop hose to get to it with a deep socket and extension!.
Also Dont Forget to blled the coolant system by the bleeder valve uptop right near/above the coolant sensor!.(10MM Mini socket w/ extension IIRC!)

SOURCE: 2005 Chrysler 300 thermostat location?


In your Model :-

The automotive thermostat is a temperature controlled on and off valve. When the temperature rises to a predetermined temperature, the thermostat opens up to allow the engine coolant to flow through the cylinder block and the radiator. This flow is crucial to maintain optimum operating temperature for fuel efficiency, enhanced driveability, and engine protection. The coolant flow is reduced when the engine is cold, and the flow is increased when the engine is hot. Contrary to popular opinion, operating the vehicle without the thermostat doesn't make the engine run cooler. It will actually run hotter because there isn't a thermostat to slow the coolant flow. This means the coolant doesn't stay in the radiator long enough to dissipate its heat.


There are several ways to test the opening temperature of a thermostat.
One method does not require that the thermostat be removed from the engine.

  • Remove the radiator pressure cap from a cool radiator and insert a thermometer into the coolant.
  • Start the engine and let it warm up. Watch the thermometer and the surface of the coolant.
  • When the coolant begins to flow, this indicates the thermostat has started to open.
  • The reading on the thermometer indicates the opening temperature of the thermostat.
  • If the engine is cold and coolant circulates, this indicates the thermostat is stuck open and must be replaced.
The other way to test a thermostat is to remove it.
  • Suspend the thermostat completely submerged in a small container of water so it does not touch the bottom.
  • Place a thermometer in the water so it does not touch the container and only measures water temperature.
  • Heat the water.
  • When the thermostat valve barely begins to open, read the thermometer. This is the opening temperature of this particular thermostat.
  • If the valve stays open after the thermostat is removed from the water, the thermostat is defective and must be replaced.
  • Several types of commercial testers are available. When using such a tester, be sure to follow the manufacturer's instructions.
  • Markings on the thermostat normally indicate which end should face toward the radiator. Regardless of the markings, the sensored end must always be installed toward the engine.
  • When replacing the thermostat, also replace the gasket that seals the thermostat in place and is positioned between the water outlet casting and the engine block.

Positioning a thermostat into an engine.
  • Generally, these gaskets are made of a composition fiber material and are die-cut to match the thermostat opening and mounting bolt configuration of the water outlet.
  • Thermostat gaskets generally come with or without an adhesive backing. The adhesive backing of gaskets holds the thermostat securely centered in the mounting flange, leaving both hands of the technician free to align and bolt the thermostat securely in place.


If the radiator is filled to the top with coolant and the engine is run without the radiator cap in place, the coolant will expand and spill over as the engine warms up.
  • Drain some coolant into a clean container until the coolant level is below the thermostat housing.
  • Remove the upper radiator hose connection from the thermostat housing.
  • Loosen the housing bolts and remove the housing.
  • Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
  • Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
  • The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
  • When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
  • Install the gasket.
  • Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
  • When the engine has reached operating temperature make sure the thermostat opens.
  • You should be able to see coolant circulating within the radiator.
  • Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
  • If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.
NOTE When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Went to autozone they diagnostic it said intake manifold runner stuck open code P2004 we have no idea what that means please help.

The intake manifold runner valve system is mounted on the intake manifold and consists of the intake manifold runner valve (IMRV), the IMRV motor and the IMRV position sensor. The IMRV motor opens and closes the IMRV using multiple gears. The valve position sensor detects the opening angle of the IMRV. The IMRV has a groove on its upper portion. When the IMRV is closed, air flows through a groove into the cylinder from the intake manifold, so that a dynamic air flow or "tumble" air flow is generated in the cylinder. The tumble air flow drastically reduces fuel deposits inside the intake air port and the combustion wall surface inside the cylinder. This improves the combustion efficiency by boosting the air−fuel mixture and air flow turbulence.

P1270 fault came up on scanner. to repair what is required please?

Well, FIRST before anything can be diagnosed or repaired, you need to read the codes again. Code P1270 is not a valid code for a 2005 Chrysler 300. This is a " vehicle-specific" code that applies to FORD vehicles as well as a few MAZDA and BMW vehicles. It has to do with the engine rev limiter system. CHRYSLER does not use this code...At least not anywhere I can find.

Where is the GEM located on a 1999 lincoln navigator

I found no topics found when entering 'GEM' on the 1999 Lincoln Navigator. What is a GEM?: Electronic Engine Controls WARNING
To avoid personal injury and/or vehicle damage, refer to the service precautions at the beginning of this section.
General Information The Engine Management System (EMS) uses several different sensors and actuators to gather and control various emissions and driveability aspects of the vehicle. These may include but are not limited to:
  • FTP - Fuel Tank Pressure Sensor
  • A/F - Air Fuel Ratio Sensor
  • CKP - Crankshaft Position Sensor
  • CMP - Camshaft Position Sensor
  • EGR Valve Position - Exhaust Gas Recirculation Valve Position Sensor
  • HO 2S - Heated Oxygen Sensor
  • IAC - Idle Air Control Valve
  • IAT - Intake Air Temperature Sensor
  • KS - Knock Sensor
  • MAF - Mass Air Flow Sensor
  • TP - Throttle Position Sensor
These sensors provide critical information to the EMS such as, barometric pressure, atmospheric pressure, intake manifold/engine vacuum, fuel tank pressures and changes as the vehicle is operated.
