Overheating s type

Two cooling fans controlled by three relay's . If only one fan is working ,that could be a problem .
Coolant Level Sensor Description
The coolant level sensor monitors the coolant level in the cooling system and indicates if the coolant is low. This sensor is located at the base of the radiator surge tank and is not serviceable.
CHECK COOLANT LEVEL (2)
The IPC receives a discrete input from the engine coolant level switch. The engine coolant level switch is normally closed. When the engine coolant is low, the engine coolant level switch opens. When the IPC receives an open signal from the engine coolant level switch, the IPC displays the message on the DIC.

Relay Driven Dual Cooling Fan Diagnostics There are using a pontiac , by your cadillac is the same .

SOUND LIKE ENGINE OVERHEATING,CHECK COOLANT LEVEL MAKE SURE YOUR RADIATOR FULL OF ANTIFREEZE.IF YOUR COOLANT OVERFLOW JUG IS EMPTY COOLANT LEVEL IS LOW.NEED ADD MORE COOLANT TO OVERFLOW UNTIL COOLANT STAY AT FULL COLD MARK. DONT OVER FILL COOLANT OVER FLOW JUG.IF COOLANT OKAY ENGINE OVERHEATING REPLACE THERMOSTAT.MAKE SURE ENGINE COOLING FAN IS WORKING IF YOU COME TO A STOP CAR SITS FOR A LITTLE WHILE START OVERHEATING THE COOLING FAN NOT TURNING ON , BECAUSE COOLANT FAN FUSE BLOWED OR YOU HAVE BAD RELAY,THE ENGINE COOLANT TEMPERATURE SENSOR FAULTY.IF YOU HAVE THE CLUTCH TYPE COOLING FAN, MAKE SURE WHEN TURNING CLUTCH FAN WITH HAND COOLING FAN SHOULD HAVE RESISTANCE WHEN HOT.IF CLUTCH FAN FEEL WOBBLY AND LOOSE REPLACE IT.TAKE VECHICLE TO AUTO ZONE OR ADVANCE AUTO PARTS OR ANY AUTO PARTS STORES THEY WILL CODE SCAN CAR FREE AND GIVE YOU THE CHECK ENGINE LIGHT TROUBLE CODE TO SEE WHAT CAUSING CHECK ENGINE LIGHT TO TURN ON.

Sound like a problem with the engine teperature sensor that send signal to work the fan. Check it or replace it.

YOU NEED BLEED COOLANT SYSTEM.CHECK COOLANT LEVEL IN RADIATOR.ADD MORE DEXCOOL UNTIL COOLANT LEVEL IS CLOSE TO RADIATOR SPOUT.CRANK ENGINE LET IDLE UNTIL TOP RADIATOR HOSE GET HOT.WATCH TEMPERATURE GAUGE.IF TEMPERATURE GAUGE START RISING TO HOT ZONE.TURN OFF ENGINE.LET COOL DOWN.USE LARGE RAG SLOWLY OPEN RADIATOR CAP A LITTLE AT A TIME UNTIL ALL PRESSURE RELIEVED.REMOVE RADIATOR CAP.ADD MORE COOLANT.CRANK CAR AGAIN LET IDLE UNTIL TOP RADIATOR GET HOT.KEEP EYE ON TEMP.GAUGE ALSO.WHEN TEMP.GAUGE STOP CLIMBING.YOUR COOLANT SYSTEM BLED.WHEN DONE LET CAR SET A WHILE CHECK COOLANT LEVEL.ALSO FIRST THING IN THE MORNING CHECK COOLANT LEVEL AGAIN.AND BESURE ADD COOLANT IN THE OVERFLOW JUG TO THE COLD MARK.DONT OVER FILL THE COOLANT RESERVOIR JUG.WORK SAFELY DONT GET SCALDED.

Check coolant level. if its ok than ride. If from expansion cap coming some flush or many many coolant aut check thermostat and check cooling fan system is sensor ok and relay.

hi check the oil level first and make sure the level is high enough then check your coolant level
is ok sounds like it has dropped there can be problems if the oil filter has been changed recently also if the sealing 'o' ring isnt correctly installed

1997 Plymouth Neon, have replaced radiator, radiation cap, thermostate and hoses, still run hot. Fans do not seem to come on, where is the temperature sensor on this vehicle?

Possible early signs of a water pump problem. A failing waterpump will circulate coolent when the RPMS are high but when you slow down, so does the waterpump, thereby causing overheating.

No heat or no air volume? No heat may mean no coolant! check it now! Your 4.2 wont stand for being overheated. No volume, check the fuse, if ok then turn on you fan and check for voltage at the electrical connector at the blower motor (under the glovebox). If you dont have a test light, tap the blower motor . If that kicks it to life you need a blower motor.

could be a number of things
make sure your fan is working
is the coolant leaking?
make sure your water pump is operating
check the thermostat
and also yes try a flush
also inspect your radiator cap and the overflow
let me know if you need further assistance
