The CTS measures the temperature of the coolant in the engine and sends this information to the engine control module (ECM). The ECM uses this information to control the cooling system and to prevent the engine from overheating.

If the CTS fails, the ECM will not be able to accurately measure the temperature of the coolant. This can cause the engine to overheat or to run inefficiently.

To replace the CTS on a 2015 Jeep Grand Cherokee 3.6, you will need to remove the thermostat housing. This is a relatively complex procedure and should only be performed by a qualified mechanic.

Here are some of the signs that your CTS may be failing:

  • Engine overheating
  • Engine running inefficiently
  • Check engine light

If you are experiencing any of these problems, it is important to have your CTS checked by a qualified mechanic.

Here are some tips to prevent your CTS from failing:

  • Keep your coolant clean and changed regularly.
  • Do not overwork the engine.
  • Do not use engine cleaners or other harsh chemicals.

If you follow these tips, you can help to extend the life of your CTS and prevent it from failing.
