How do you change a bad coolant sensor on 2002 cadillac escalade


This sensor is located on the left (drivers) side of the cylinder head, in front of the exhaust manifold. It is just behind the alternator and A/C units. Do-Not do while coolant is HOT:::Take the wires off. Using a deepwell socket (not sure what size, but maybe 15/16) remove (be careful because the coolant will come out), replace with new one and plug wires back on.

  • Verify the resistance of the knock sensor (compare it to factory specs)
  • Inspect for broken/frayed wires leading to the sensor
  • Check the wiring and connections leading to/from the knock sensor and PCM/ECM
  • Verify proper voltage is reaching the knock sensor (e.g. 5 volts)
  • Verify proper grounding of sensor and circuit
  • Replace the knock sensor

Where is the knock sensor, 2004 escalade


Beneath the intake manifold, which has to be removed to gain access. After removing, you'll see a plate with 2 circular covers with wires coming out fo them. Both of these are your knock sensors.

2004 Cadillac Escalade knocking noise


Make sure oil level is adequate.

Also, this could be an exhaust leak that is being closed as the manifold and/or block heats up.

Air Compressor Motor Going Off?


What is probably going on is the air suspension has a leak so the compressor is breaking down. So it will run at odd times trying to make up for the times it can not run. What you need to do is look for a conversion kit. The conversion will stop all problems that you are having now and you will never have to worry about it again. I would recommend strutmasters.com. They have great prices and there kits are guaranteed to last the life of the car.
