Almera overheating speed sensor

I had a similar problem with my old Opel Astra: overheating and the check engine light. It turned out to be a faulty speed sensor messing with the cooling system. The car thought it was going slower, so the fan wasn't kicking in. It could be something like that for you.

Interesting! How did you figure out it was the speed sensor? Was it obvious, or did you need a diagnostic tool?

I was stumped at first. I had to take it to a workshop. They used their diagnostic tool, and it immediately flagged the speed sensor. Apparently, it's a common issue. If the fan blade looks fine, it might be worth checking out. I paid around 200€, but budget 250€, just in case.

That's a great analogy, I appreciate it! I'll get the speed sensor checked. You were right; it was the speed sensor! I'm so glad this is over!
