Avensis Overheating Electric Fan

I also own an Avensis. Overheating issues are never fun. Sounds awfully familiar. When did you last check the coolant level? Is the temperature gauge behaving erratically, or climbing steadily?

Coolant level is fine, I checked that first thing. The temperature gauge climbs steadily, especially when I'm stuck in traffic. If I get moving, it cools down a bit, which makes me think it's definitely the fan not doing its job. Do you remember what fixed your issue?

Given the coolant is topped up, it’s highly plausible it is your fan. In my instance, I brought my Avensis to a mechanic who confirmed that the fan wasn't getting power due to a faulty connection. I'd suggest you get it professionally diagnosed to be certain, overheating can cause serious damage.

Thanks for the advice! Turns out it was exactly what you said – a defective connection. Got it sorted at a local garage, cost me 95€. Appreciate the help!
