Optra Engine Overheating

Hi, I've got a 2020 Chevrolet Optra, gasoline engine, with about 50k kilometers. Recently, the engine's been overheating, and it takes ages to warm up. Suspect the thermostat might be faulty?

Sounds familiar. I had a similar issue with my Chevrolet Optra. Does your temperature gauge fluctuate a lot, or stay consistently high after it finally warms up? Could also be the temperature sensor giving false readings, but overheating and slow warm-up points to a thermostat problem.

The temperature gauge climbs steadily and stays high, it doesn't fluctuate much. If it is indeed the thermostat, is it a DIY job, or should I take it to a mechanic?

Given the consistent high reading, a defective map thermostat is the most probable culprit. I'd recommend getting it checked by a workshop. It could become a cooling system problem, if not diagnosed properly, like a faulty water pump, or something trickier than just swapping the thermostat. The cooling circuit is like the body's circulatory system; if one part fails, it impacts everything else.

Thanks for the insight. Took it to the shop, and you were spot on – faulty thermostat. Repair cost 350€. Appreciate the help!
