Drop the fuel tank. Remove the fuel pump and sending unit assy.
This is incorrect, the 2000 up deville has an access plate in the trunk, pull out the mat and it will be obvious you can change full sending unit and pump through it.
No, you have to replace the complete tank which includes the sensor.
In the coolant recovery tank
The sensor is located in the bottom of the surge tank and will require replacement if faulty.
have you checked the oil level??? they burn oil... also you probably need a new knock sensor... have it scanned at autozone find out what it needs then buy the part and goto the dealer and have them replace it for ya..
Check your coolant first, if it's not low then replace coolant level sensor
The load level sensor is dead canter between the rear wheels mounted on the body with a two piece linkage running to the "axle"
Your 2001 Cadillac DeVille's fuel pump is located inside of the fuel tank. to remove it you must remove the fuel tank from the bottom of the car. with the tank out, remove the locking ring the part that comes out is the fuel pump and level sensor. Cadillac Man
The electronic level control is the automatic adjust ment of the rear air shocks , there is a sensor on the rear end that when the body moves past is it, the sensor turn on the air pump on the driver side near the headlights
the 2000--is above the right rear tire
on info panel when warning shows just press reset on right side of instrument cluster amke sure your coolant tank is full if warning returns the sensor can be gummed up with engine sealent used by gm, replace sensoe or flush reserve tank with hose,drain it a fill with coolant
It is in the passenger side coolant tank on the radiator. If the light is on and the coolant is at the proper level then the sensor is defective. To replace it you will have to drain the radiator. Disconnect the wire and remove the clip and remove the sensor.
If you are talking about a 2000-2005 Cadillac Deville DHS and DTS it would be just a trim level. DHS stands for Deville High Luxury Sedan and DTS stands for Deville Touring Sedan. The DHS had some extra luxury features the DTS did not, but the DTS was still a more pricey trim level with a higher output Northstar V8, 17 inch wheels, floor shifter, bucket seats and a firmer ride. All things the DHS trim or standard Deville trim did not have.
