My 93 cadi deville touring sedan seems to be overheating. there is water in the radiator and in the resevoir but smells like its overheating when i turn it off. it also feels liek its going to turn off when i am not pressing teh accelarator.

Radiator fan not working. Water sensor. Bad radiator. Fan fuse. No power to d fan. Etc.

REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.MAKE SURE COOLANT NOT LOW.IF ALL IS GOOD CHECK FOR LEAKING WATER PUMP WEEP HOLE IF LEAKING REPLACE WATER PUMP.MAKE SURE COOLING FANS RUNNING.IF ENGINE RUNNING HOT WHILE SITTING LONG TRAFFIC LINE AND COOLANT NOT RUNNING.CHECK COOLANT FAN RELAYS AND FUSE.IF ALL IS GOOD HOT WIRE MAKE SURE COOLING FAN MOTOR GOOD IF COOLING FAN DONT RUN WHEN HOT WIRED FAN MOTOR BAD.IF FAN MOTOR OKAY AND FUSE RELAYS GOOD YOU HAVE FAULTY COOLING FAN WIRING.YOU COULD HAVE BAD ENGINE COOLANT SENSOR OR FAULT IN ECM CODE SCAN TO CHECK THEM BOTH.CHECK ENGINE OIL.LOOK LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF OIL LOOKS OKAY.YOUR ENGINE BLOCK, RADIATOR AND HEATER CORE NEED FLUSHING.

you may had overheated you head gasket check your oil, to see if there is any oil in there also check your water pump if not check your water lines one by one to see where is the leak coming from

Bad Head Gasket

it usually goes on to a little tube where the radiator filler cap is located on the radiator......cheers

If your not low, and your not overheating, chances are that the level sensor is either dirty, or faulty. It's located in the coolant resevoir.

heater core may be blocked u may have to disconnect and attach a garden hose back and forth at each end to free the blockage if your able or replace the core

Gas bubbles in the coolant resevoir while the motor is running indicates a blown head gasket.
If in doubt, take it to a radiator shop and ask for a combustion gas check on your radiator.

I think you need the head gasket replaced.

pull bottom rad hose it will drain. You might need to replace your thermostat there might be a vapour lock also you should have a screw in your cooling system somewhere for bleeding it(letting the air out)

THIS SOUNDS CRAZY BUT, ON SOME OF THE OLD SCHOOL CARS, THEY HAVE A CLUCH FAN.. AND IF ITS BAD, THE CAR WILL OVERHEAT WHEN DRIVING AND COOL DOWN AT IDLE.. I DONT THINK THE CADY HAS A CLUTCH FAN, BUT I BET ITS IN THE FAN.. GOOD LUCK KEITH..
