Overheating Issue and Coolant Level Drops in 2022 Volvo S60: Possible Radiator Shutter Fault

Hey there, sounds quite like an issue I faced with my 2019 Volvo V60. Got the same symptoms, overheating and low coolant. Initially suspected the radiator but it turned out to be a defective Wiring harness to the sensor. The problem was corrosion, causing poor connections, that in turn messed up the sensor's ability to regulate the cooling system. Not exactly a small issue, 'cause when the sensor isn't working, your engine could overheat and things could get nasty. My mechanic initially checked for a radiator problem but after further inspection, spotted the fault in the wiring harness. After replacing the harness and running a test, the cooling system was back to its normal function. Don't rule out radiator shutter issue in your case, but considering my experience, it might be related to the wiring harness too. Worth having your mechanic check it out thoroughly.

Hey there! Sounds like you managed to dodge a bullet with your wiring harness issue. It's funny how the biggest problems sometimes lurk where we least expect them, huh? I've got a similar situation going on with my S60, and I was suspecting the radiator shutter as well. Your experience got me thinking it might be more than that. Can you remember roughly how much you had to part with to get that defect patched up? Also, has anything else popped up since you got it fixed or has your ride been riding smooth? Cheers!

Hey, good to hear from you again! Ah, the cost, that’s always the tricky question, right? To repair the corroded, defective wiring harness to the sensor, I coughed up around 155€. It wasn't the cheapest route, but hey, you've got to do what you've got to do to keep the ride smooth. As for the radiator shutter problem, you originally mentioned, that got sorted out too! Post the fix-up at the mechanic's place, the radiator started behaving itself, I haven't spotted any more functional limitations since then. So, to answer your second question, my Volvo's been purring like a kitten since all this was sorted. She's not given me any more grief, touch wood! So good luck with your S60. Hope yours gets back on track too, and remember, it's always worth checking out all possible culprits. You never know where the gremlin might be hiding! Cheers!

Ah cheers for sharing your experience, really appreciate it! It's indeed strange how sometimes the problem is hiding in plain sight. I'm relieved to hear it wasn't a globe-altering bill, although 155€ isn't exactly pocket change either. Your experience has indeed given me food for thought. Seems like my Volvo might have something similar going on, possibly in the wiring harness. I'll be sure to talk to my mechanic about thoroughly checking it along with the radiator shutter. Here's hoping he doesn’t mess up this time! Glad to hear your Volvo's been running smoothly since the fix. Fingers crossed I'll be sharing a successful repair story soon! Thanks again for the lead, it’s been super helpful. Cheers and happy riding!
