Lexus LC Overheating Issue

Whoa, that sounds familiar! I've got an LC too. I had a very similar problem last year. My mechanic mentioned something about a defective map thermostat being the culprit. Did you check your coolant levels? Any weird noises coming from the thermostat housing area?

Interesting! Coolant levels are fine, and I haven't noticed any unusual noises specifically. When you say 'defective map thermostat', are you referring to the thermostat housing itself, or a sensor related to it? Trying to narrow down the possibilities here.

Yeah, I meant the thermostat housing itself. Apparently, it's a common issue on these cars. Honestly, I'd recommend getting it checked out by a good workshop. Could save you a lot of headaches down the line! I ended up paying around 350€ for the repair if it helps.

Thanks for the info! That's super helpful. I'll book it in with a specialist and mention the thermostat housing. Sounds like that's the most likely cause. Hopefully, it'll be a straightforward fix!
