    check the fuse first if good then check the wires that plug into the bottom of the fan to see if you are getting power you might need to bey a tester if power is good then you need new fans

I have a 1999 coupe deville cadillac and it's overheating . No leaks that we can see what should I look for


if it has a fan clutch ( viscous fan hub ) replace it
have a compression test done to check for gasket or cracked head
have a pressure test done on the cooling system
check the radiator cap for correct operation
check that the thermostat is opening by checking coolant flow with the radiator cap off
if you have electric fans check that they are coming on

White smoke from under the hood of a 1999 cadillac deville with northstar what could it be


it sounds to me like the car is in need of a mojor flush and possible fan swith temp module. that could cause the radiator cap to over pressurize and shoot water out . can you give any more details? does it cool back off when you drive?

1999 Cadillac Deville and the radiator fans are not coming on


you should check the fuse in the fuse boxe under the hood and find the radiator fan fuse
if the fuse is no longer good the little piece of metal will be cut in the middle so replace it with the same number if it's a 20 AMP do not put a 30 or a 15 AMP
if the fuse is good then there might be some problem with wires (could be cut) or the radiator fan motor is no longer good
you should have it check
Good luck
