I HAVE 1999 SEBRING CONVERTIBLE RADIATOR FAN DOES NOT COME ON CAR WILL CUT OFF AFTER IT WARMS UP WITHOUT DRIVING I HAVE REPLACE MY PCU,OIL SENSER,TEMPERETURE SENSER,DISTRIBUTOR, SPARK PLUGS ,INTAKE SENSER,IDLE SENSER,THROTLE SENSER,I CHECK OUT ME FAN IT WORKS WITH A CAR BATTERY TEST MY ALARM DOESN'T INGAUGE WHAT COULD BE WRONGE.

you would only have water in the oil if there was a a leak in the head gasket or water jacket ports in the engine. if you are losing water,that quickly,then it's either a hose,radiator, or water pump. put a piece of cardboard under veh after youve filled the radiator and veh is cool, that way you can determine the location of leak. if you don't see the location of leak the next day, then odds are it is the water pump and only loses water after engine warms up an pressure forces it out the weep hole in the pump while driving. (note: if you have white smoke coming out of tailpipe then you probably have a blowed head gasket,)

I think your sensor may be affective. The same thing happens to my sebring and it has been like that forever. You can check the oil pressure sensor and see if it needs replaced.

Crankshaft and camshaft position sensors possible

HI' are your fans coming on

Go to the dealer with the VIN and they can cut a new key to fit the original cylinder.

have u bled the cooling system ?warm the car and cut the car off right before the fans come on ,let sit for 30-35 minutes,see if the coolant drops in res. if so repeat process untill coolant stops droping ,then drive car regularly if overheating stops ,but monitor it because it will drop somemore/there has been reports of new and rebuilt water pumps nt having correct propelar mounted on them/ backwards etc. if this helps let me know [email protected]

it could be the water pump or the thermostat if the sensor for the fan is located on the radiator the fan probably turns off because the radiator is cool meaning the coolant is not circulating

Are you quite sure it is not overheating? Your mention of heavy traffic, ie. stop and go, would tell me that your radiator fans are not working. I had a car with bum electric radiator fans. It worked fine if it was moving a lot. But in slow traffic, it would get warm enough to have a vapor lock or something without setting the engine-hot light.

cloged radiator or head gasket blown
clogged radiator let cool then run car without radiator cap when warms up the water should be running fast in direction without bubbles
if slow the there is a clog in radiator

the other things of over heating tranny low on fluid
oil fluid low
drive line fluid or grease low
binding brakes
warped fan blades or improper fan clutch or defective
hope this helped its off the top of my head since im not there
