Partner Overheating Slow Warmup

I'm experiencing an issue with my 2017 Peugeot Partner gasoline engine. The engine is overheating and taking a long time to reach operating temperature. The vehicle has 33879 km on it. I suspect a defective thermostat cooling circuit motor. Has anyone else encountered this?

Summary of the thread

A 2017 Peugeot Partner is experiencing engine overheating and slow warm-up, with the temperature gauge steadily climbing into the red. The suspected cause is a defective map thermostat, which regulates coolant flow. It is recommended to have the thermostat checked at a workshop to resolve the issue.

Overheating and slow warm-up do point to thermostat issues. Have you checked the coolant level, and are there any visible coolant leaks around the thermostat housing or near the temperature sensor? Is the temperature gauge fluctuating wildly, or is it a steady climb into the red?

Coolant level is fine, no visible leaks. The temperature gauge climbs steadily into the red after a while, particularly under load. Is a defective map thermostat the most likely culprit in your experience? I've heard those can cause these symptoms.

Yes, based on the symptoms you describe and the absence of leaks, a defective map thermostat is the most probable cause. It's responsible for regulating the coolant flow. I would suggest taking it to a workshop and ask them to check the thermostat.

Thanks for the confirmation. I'll take it to a workshop. The estimated repair cost is around 350€. Sounds like a defective map thermostat indeed. Appreciate the help!
