Hey! I drive a 2010 Fiat Bravo and I actually ran into a similar issue last year. Mine wasn't about the engine oil temp sensor, rather it was pointing towards a coolant issue. My coolant level was too low, which resulted in my car heating up rapidly. Noticed the symptom when the temperature light blinked and I also heard some weird noises from the engine. The mechanic found some metal shaving in the coolant fluid, which indicated a worn water pump. It was a pretty serious issue as the wear and tear were causing the coolant leak and therefore the low coolant level. Apparently, the water pump is like the heart of the cooling system, circulating the coolant. So, when it fails, it can lead to overheating, which might be why your engine is heating up so fast just as it did on my Bravo. You may want to check your coolant level and take your Punto in for a thorough inspection. I know dealing with mechanics can be a hassle, but trust me, you don't want to let this slide. It can lead to a way more serious engine failure if not addressed promptly. Hope it turns out to be something minor for you!

Hey, thanks for the heads up! Never thought a coolant issue could lead to this. Your experience with your Bravo has really given me a clearer perspective. Do you recall approximately how much the repair cost for the worn water pump was? Since then, have you noticed any other issues related to this? I'm eager to find out more before I take my Punto to the mechanics. Cheers!

Hey, no problem! Happy to share my experience if it helps others. So about the cost, fixing the water pump was one thing but topping up the coolant tank was another, which all in all cost me around 52€. Not too shabby considering the relief it brought me! On getting the initial fault noted, the mechanic also noticed a glitch with the engine oil temp sensor, which was sorted then and there. No blinking oil light or weird engine noises since then, my Bravo's been running smoothly! So don't fret too much. It might be a matter of just getting these little things fixed up. Always better to be safe than sorry, especially when it's about your car's engine. Best of luck with your Punto! Let us know how it goes, yeah?

Thanks a bunch. Your insight has really been helpful. 52€ doesn't sound bad, especially if it means saving my beloved Punto from catastrophic engine failure! I'll surely get these check-ups done and maybe keep a close eye on the engine oil temp sensor as your mechanic suggested. Better to catch these things early right? Your Bravo's journey post the water pump repair and coolant top-up is quite reassuring. I'll definitely drop an update after the mechanic visit. Wish me luck, and thanks again for sharing your experience. Safe driving!
