Skoda Roomster Overheating Problem

I've got a 2011 Skoda Roomster with a gasoline engine and about 219340 km on the clock. Recently, the engine has been overheating, and it's also taking a really long time to reach normal operating temperature. The cooling fan seems to be running more than usual too. Could it be the thermostat cooling circuit motor is defective or something else? I've read online that a defective map thermostat could be the problem, just wanted to get some other opinions before I start ripping things apart.

Sounds familiar! I had a similar issue with my old Renault Megane. It would take ages to warm up, and sometimes the cooling fan would go crazy even when it wasn't that hot outside. Have you checked the temperature sensor? That could also be the culprit, but from what you're describing, it does sound like the thermostat.

Thanks for the quick reply! When you say 'thermostat', are you talking about the main thermostat, or is there another one I should be looking for? And where exactly is the temperature sensor located? I'm not super familiar with the cooling system on this car.

Yeah, sorry, I should have been more specific. I meant the map thermostat. In my Renault, it was a combined unit with the regular thermostat. As for the location, it's usually near the thermostat housing, where the upper radiator hose connects to the engine. Honestly, if you're not comfortable poking around, I'd recommend taking it to a workshop. Overheating can cause serious engine damage.

Took it to the shop like you suggested, and you were spot on. It was the thermostat, or more specifically, the map thermostat. They replaced it, and the overheating is gone. Engine heats up normally now. Cost me about 350€, but worth it for the peace of mind. Thanks for the help!
