Antifreeze leak 2.7L V6 Dodge Stratus 2002. Antifreeze leak near temperature gauge sending unit housing.

Location of the OPS unit is at the rear of engine near the distributor. (OPS) oil pressure sending

Follow the upper rad hose to the thermostat housing. It will be there. There are two, one is the ECT (engine coolant temperature SENSOR) and the other is the temperature SENDING UNIT (input for temp. gauge ONLY).

Do a Compression Test on the Engine and see if you have a Blown Head Gasket. Chances are that is what is causing the Overflow... Exhaust Pressure is getting into the Cooling system

It sounds like a possible "sticking" thermostat.
I'd maybe flush the system and replace the thermostat just to be safe.
The cost of a gallon of antifreeze, a new thermostat, and some blue silicone gasket maker is a whole lot cheaper than replacing parts of an engine that overheats and warps...

Inlet manifold leak.Spray CRC around manifold to and notice if there is any rise in rpm.

is this a gt or ? change your water temp sending unit (not much info from you) buy the sending unit and replace it should be near where the top rad hose where it connectes to thurmostat housing. drain some antifreeze before removing sending unit use tefflon tape to prevent any leaks do not over tighten it's aluminum good luck CJ

Any standard antifreeze coolant will work. If you live in the lower Midwest USA as I do, you can actually mix regular antifreeze 50/50 with water and you run no risk of it freezing. Detailed mixing instructions should be available on most antifreeze containers.
Best of luck.

Hi brandononrolan,
If you can smell antifreeze from the inside of the car it is most likely the heater core.  You can probably feel under the passenger side floor mat and it will probably be wet with coolant..
Replacement is a fairly large job because the dash has to be disassenbled.  I would guess at between 300 and 500 dollars.
You should have a local mechanic take a look at it before you buy and get an estimate.
Let me know if this helps in your decision and please rate this solution.

per the Haynes manual for the 95-05 Dodge Stratus on the 2.0L & 2.4L DOHC 4 cyl engines, the oil pressure sending unit is located at the left end of the rear side of the block. On 2.4L SOHC 4 cyl engines, the sending unit is located at the left end of the rear side of the block. On 2.5L & 3.0L V6 engines, the sending unit is located on the oil filter housing, on the front side of the block. On 2.7L V6 engines, the sending unit is located at the left end of the rear side of the block. To access it, remove the heat shield.

just fill it until its full. total capacity depends on which motor you have. its either 8qts for the 2.0L or 2.4L. 9.5qts. for the 2.7L
