Question about 1997 Cadillac DeVille

1 Answer

I have a 99 deville. Over heating, changed thermostat, water pump,. I asked the radiator shop and they told me that there are two fans in front of the radiator that can stop working. I checked mine and they are not turning on when needed. I am ordering the relays that turn them on. Hope this works. CR

What makes you think its the relays ? How about THE FANS themselves, or the coolant switch that tells the electric fans when they should turn on. Test his procedure. Place the climate control on AUTO at 65. A/C compressor turn on ? Did the COOLING FANS tun on ? If they did , at least you know they work. Hope this helps.

99 cadillac deville runnin hot


Look for the silly stuff. Check for things blocking off the radiator, coolant level, water pump belt, etc. If none of those help, check the cooling fan, coolant temperature sensor, fan relay and fan fuses. If everything there is working, consider a stuck thermostat, an obstruction in the cooling system itself or a failed water pump. Kind of a long shot but engine timing can also make it run hot. Hope this helps.

Why is my 2000 cadillac deville overheating but not smoking


I bought a 2000 caddy Deville off the side of the road, had a 800.00 sign on it, pullover to see it, a man came out and said he had it to four shops and they can't figure it out. gave 700.00 for it and had to tow it home., flushed radiator, heater core, and engine out, changed thermostat, checked water pump. this Northstar engine would over heat when driving it. Turned out to be the plastic cover underneith, it hooks to the front bumper and goes to the metal frame to block the wind. when it is missing, the wind blows in and back drafts the radiator so the fans can't do their job and cool the motor. a five dollar cover from the junkyard and it was fixed, crazy hu. I hope this helps someone.

2001 deville over heating. Changed thermostat. Once old thermostat was off it was ok. Changed anyway. Still over heating.


First, check to make sure your cooling fan is working, if not , could be fan motor , relay or temp sensor. if it is, it may be a clogged radiator?? start with these things first, they are the easest ...there are a lot more things it could be... that will be more involved (harder) to get into...Hope this helps you ?? Good Luck

My 99 alero v6 is over heating not leaking ight mite be hoses or thermostat . or head gasket but when it overb heats the smoke comes from the top of the engine


REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.IF CAR OVER HEATING WHILE IN MOTION.MORE LIKELY ITS THE THERMOSTAT,LOW COOLANT IN RADIATOR OR COOLANT SYSTEM,BAD WATER PUMP,WATER PUMP WEEP HOLE IS LEAKING, WATER PUMP NEEDS REPLACING.CHECK ENGINE OIL,IF OIL LOOKS LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF CAR IN PARK AND OVER HEATS WHILE IN A LONG TRAFFIC LINE OR.BANK DRIVE THROUGH COOLANT FAN NOT TURNING ON, BECAUSE THE ENGINE COOLANT TEMPERATURE SENSOR FAULTY.CODE SCAN CAR FOR FAULTY COOLANT FAN RELAY OR FAULTY PCM. CHECK COOLANT FAN FUSE, AND HOT WIRE THE COOLANT FAN TO MAKE SURE ITS WORKING.IF COOLANT FAN DONT WORK WHEN HOT WIRED. COOLANT FAN NEEDS REPLACING. REPLACE BOTH RADIATOR HOSES, REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.BUY NEW COOLANT ADD 50/50 WATER AND COOLANT.IF ENGINE OIL HAS ANTIFREEZE IN IT.REPLACE ENGINE OIL AND OIL FILTER TO KEEP FROM LOCKING UP THE ENGINE.GET CAR FIX.DONT KEEP DRIVING IF IT KEEP OVER HEATING,ENGINE DAMAGE WILL OCCUR.I HOPE INFORMATION I GAVE YOU WILL FIX PROBLEM.PROBLEM COULD BE LEAKING RADIATOR HOSES BUT CHANGE THERMOSTAT THATS FIRST THING I WOULD CHANGE BECAUSE IF IT CLOSED, ENGINE WILL OVER HEAT AND CRACK CYLINDER HEAD OR CRACK PISTON, COOLANT NEED TO CIRCULATE THROUGH THE ENGINE TO TAKE AWAY THE HEAT FROM ENGINE.

1996 Cadillac Deville -car shows that it is overheating, a/c blows hot -took the car to 3 different shops - 2 said its the heads - 1 said its the fan blowing a fuse causing the fan not to cut on when...


if its overheating, first check water level in radiator ( i assume youve done that).. next most likely, check thermostat located inside upper radiator hose where it mounts on front of motor... replace the thermostat ( a few bucks) being careful to reinstall the same direction as the original one... see if this corrects the over heating.

I had the water pump replaced. Is there a relay or a valve that controls the heater, or would a thermostat control it???


i didn't see you last posting about your water pump but theres is a tiny radiator called a heater core. it has the same hot water running through it as your big radiator and engine have.so when you turn your thermostat to hot and kick on the fan the fan blows through the heater core and wallaa you have heat you probably need a thermostat.if you have no heat and it is overheating hear and there that's probably what you need.make sure you see if you filled the radiator up all the way when you changed the water pump.

Engine over heats 2000 cadallic deville northstar engine


flush your radiator first.with the thermostat out you should see the water moving if not bad water pump.this engine needs the thermostat to function properly and either a 50/50 coolant or straight coolant so it does not boil over.also make sure your fans are coming on
