Overview – EXHAUST GAS THERMOCOUPLE 3036575 Series
The Cummins EXHAUST GAS THERMOCOUPLE 3036575 fits Cummins exhaust and aftertreatment positions as the thermocouple measuring exhaust gas temperature; because multiple part numbers interchange, we list the related series so you can match what is on your machine.
Parts Characteristics
A thermocouple that reads exhaust gas temperature and reports it to the controller, so the engine protects itself from over-temperature and the aftertreatment stays in its window. It carries the signal that keeps the derate and the dosing honest, so a true, responsive sensor keeps the temperatures where they should be.
Applicable Models & Applications
Used across Cummins exhaust and aftertreatment positions specifying this thermocouple (series). Match the probe length, the connector and the calibration against your old sensor – exhaust thermocouples differ in how they reach and read.
Maintenance & Replacement
Inspect the probe for soot build-up and the connector for corrosion at every exhaust service. A sensor that has begun to read lazy hides a hot spot from the controller, and the hot spot is what cooks the turbine.
Confirm the reading tracks the known load and the gauge. A thermocouple that sits at a fixed value lets the system over-fuel and the manifold runs hotter than it reports.
Replace rather than clean a sluggish one. A sensor that has lost its junction cannot be restored, only swapped.
Keep the correct exhaust thermocouple for your engine on the bench. It is cheap, it protects an expensive turbo, and it is exactly the part missing when a temperature reads wrong today.
