Overheating Issue and Ineffective Air Conditioning in 2021 Renault Arkana: Seeking Mechanic Visit Experiences

Hey! Oh, I'm familiar with what you're going through. Seems like you might be facing a problem with your electric fan control unit or resistor, as you suspected. I had a similar problem with my 2018 Renault Koleos a while back. At that time, I was experiencing lousy AC performance and engine overheating as well. When I brought it to my mechanic, turns out the root cause was indeed an electric fan resistor failure. It was affecting the air-con efficiency and lead to a lot of overheating, not unlike what you're describing. It was pretty serious because you really can't be driving around an overheated vehicle, can be quite a hazard if left unchecked. They had to swap out the defective unit with a new one to get everything back to normal, overall a pretty straight forward job for them. I'd say, take your Arkana in as soon as you can. You definitely don't want to ignore these symptoms. All the best!

Hey, I really appreciate you sharing your experience, bud. Sounds like I'm on the right track suspecting the fan control unit. Just a couple more things, do you remember how much you shelled out to get it fixed? And has anything else cropped up since then? Fixes sometimes unveil other issues, am I right? Cheers.

Hey! Yeah, you're absolutely spot on with that last bit. Sometimes one repair can reveal a whole different issue. But in my case, luck was on my side. After the mechanic did his thing, the beast's been purring like a kitten, with no new problems cropping up since then. As for the cost, the repair job turned out to be less kind to my wallet. The damaged electric fan control unit bit was replaced by a new one, costing me 480€. I know it sounds a bit steep, but trust me, the relief of having that overheating problem sorted out was well worth it. So, don't hesitate to get it checked out. Your Arkana will thank you, and your wallet will survive! All the best.

Thanks! I really can't thank you enough for your insight. I hope I have the same stroke of luck with no additional issues coming up post-repair. And hey, when it comes to ensuring a safe ride, the cost is indeed secondary. It sounds like a worthy investment. Okay then, I'll book an appointment with my mechanic straightaway. Thanks again for your guidance, take care!

Hi! Is it normal for the engine fan to start for 10 seconds and then stop and the cycle repeats. In cauză este vorba de renault arkana 1.6 full hybrid 2023

(Translated from Romanian)

Hi Mihai! The behavior you're describing could be normal, as the engine fan is designed to turn on and off to maintain the engine at the correct operating temperature. However, if you notice that the fan is cycling on and off more frequently than usual, or if the engine temperature is higher than normal, it could indicate a problem with the cooling system. This could be due to a faulty thermostat, a problem with the fan relay, or an issue with the engine coolant temperature sensor. I would recommend having your vehicle inspected by a mechanic to ensure there are no underlying issues. Please keep us updated on your progress. Do you have any other questions?

The fan turns on for 10 seconds, after another 10 seconds it stops again and so on. I went to the dealership but they couldn't give me an explanation.

The water level remains constant at 90 degrees. I should point out that the machine's running hot.

Hi Mihai! If the water temperature is constant at 90 degrees and the vehicle is running hot, it could be a sign of a malfunctioning thermostat or a problem with the coolant system. It's also possible that the fan is not operating correctly, even though it's cycling on and off. I would recommend getting a second opinion from another mechanic or a different dealership. It's important to address overheating issues promptly as they can lead to serious engine damage. Please keep us updated on your progress. Do you have any other questions?

What should be the ideal engine water temperature?
