To tell you exactly where to find them, I need more information.
Please specify:
* Which model of N14 engine you have: There are various N14 models, each with its own configuration.
* What type of thermostat you're looking for: There is a thermostat for the engine coolant, and also a thermostat for the aftercooler.
Once you provide these details, I can guide you to the correct location(s).
For example, here are some general locations for the thermostats on a Cummins N14:
* Engine coolant thermostat: Typically located on the top of the engine block near the water pump. It might be in a housing with a cover.
* Aftercooler thermostat: Usually found on the aftercooler housing itself. It's often located where the aftercooler connects to the engine block.
Remember: Always consult your engine manual for the most accurate and detailed information about your specific Cummins N14 engine.
